Submit entries for new CGS members’ selling show: Flora

Many CGS members took part in our recent successful online selling show, so we asked renowned glass artist Cathryn Shilling if she would provide the theme for our next inspiring opportunity for members to show and sell their work.

Cathryn says: “I have spent a significant amount of time this winter gazing out of my kitchen window into my garden and reflecting on the year that was (or wasn’t as the case may be). Let’s face it, 2021 has not started in the way any of us had hoped for…

“Of course, winter is transient, like any season, but I have to admit that staring into the thickening snow in the midst of another national lockdown, it does feel a little like we are all living in the eternal winter of Narnia… However, even in Narnia, winter came to an end and, as I looked out over my frozen flower beds this week, I noticed the first signs of life returning to my garden in the form of snowdrops and the shoots of ‘soon to be’ daffodils. Surely this is the herald of Spring and a promise of better days to come?

“The remarkable diversity of flora has been a major source of inspiration among glass artists throughout the centuries – from the simplistic interpretations in medieval stained glass, through the cast crystal of Daum and the cameo glass of Gallé, to the cutting edge and contemporary interpretations demonstrated by many of our talented and endlessly resourceful CGS members.

“It is this endless circle of resourcefulness which brings me back to Nature, and how even in the bleakest and coldest of places, nature is able to adapt, spreading colour over barren landscapes, transforming them into a majesty of pattern and colour.

“So, I would like to challenge CGS members to participate in a new online selling exhibition inspired by the incredible diversity of ‘Flora’. This brief is extremely broad. How you choose to interpret it is entirely up to you. My greatest wish is to see as many unique examples on the subject, as there are species of flowers!”

This is an exclusive online selling show for CGS members only. If you are not a member yet, you can join today to benefit from this opportunity.

CGS members please log in to your account and load an image of your piece for sale on the theme of Flora by the deadline of 29 March 2021. This online selling show will take place from 3 April to 5 May 2021.

 

 

Practice makes perfect: glass artist Wayne Cain

Renowned glass artist Wayne Cain explains how his father influenced his own resourcefulness in learning and mastering a variety of skills, including stained glass, flameworking and bevelling – skills which have kept him at the top of the creative glass world for decades.

My father was known as a man who could do almost anything. He was a sheet metal mechanic by trade and would often take me with him when he worked on Saturdays, giving me tasks appropriate to my age and paying me 50 cents an hour out of his own pocket.

Wayne Cain and his father, Jacob Wayne Cain, circa 1951.

Soon after moving into our new home, which had just stud walls and insulation upstairs, my father informed my brother and me, aged about 11, that, if we wanted finished bedrooms, we would have to complete them ourselves: “I’ll show you the first step; you have to do the rest.”

Sure enough, he showed us how to hang one sheet of Sheetrock, how to tape one joint, trowel over it with joint compound, and cut and nail one piece of moulding.

I remember so well the emotional impact this had on me. I was quite upset that my father would not help beyond his initial instructions. Until this time, I’d had the impression that everyone worked together to achieve our goals. All of a sudden, I was faced with stud walls, some unfamiliar materials, and a few simple tools.

Another part of me saw the potential in my current situation. I was beginning to envision myself as an adult, someone who, in a few years, would be independent. I sensed that I was beginning to build a human being – myself – and that I could become the person I wanted to be.

The trial-and-error process came quickly and naturally to me: learning to drive a Sheetrock nail so it settled just below the surface without tearing the paper; applying just enough joint compound so the tape joint would end up flush with the finish surface; cutting the correct angle on moulding and sinking a finishing nail just below the surface.

The years I spent finishing off my bedroom stand out to me because I was on my own, doing and thinking. It developed in me a deep sense of self-confidence, knowing that I was developing processes that would help me when faced with the unknown later in life.

My father died of a heart attack when he was 43. I was 17. This devastating and final chapter in our relationship signalled to me that I was truly on my own and that I was responsible for my life.

The following year I was accepted into college. My family did not have money for such excesses, so I took our ladders and a couple of paintbrushes and painted neighbourhood houses, making enough money each summer to pay my way through. This was, in large part, a tribute to my parents for the self-sufficiency they instilled in me.

I thought a lot about how I wanted to live my life. I knew that I would not fit into the corporate world. I knew that I wanted to be compensated for the value of my development and not give it away to someone else. I also thought that one should work, make the money needed, and spend the remainder of their time enjoying the other things life has to offer.

Most importantly, I wanted to self-actualize. I wanted to apply my problem-solving skills to the real world.

Out of college, I thought about becoming a blacksmith, perhaps a copper smith. I was also fascinated by light filtering through treetops, the translucency of nature.

Flameworked flowers bring 3D interest to a stained glass window.

This love of light helped me decide, in June 1972, to climb into my 1964 VW bus and drive from Richmond, Virginia, to Rockland, Massachusetts, to the Whittemore-Durgin Glass Company. I remember sleeping in my bus to save every cent I could to buy the basic tools and materials I needed to begin my chosen journey of working with glass.

Starting on the kitchen table, I made stained glass apples, pears, cherries and chickens that stood on one leg, selling them at craft fairs and gift shops. From there, it was ‘Tiffany’ type lampshades, windows – including learning how to repair both – as well as curved shades.

A local plate glass company offered to sell me their 1915 Henry Lang bevelling machines. At the time, I couldn’t find any literature on how to bevel so, once again, I relied on the trial-and-error process.

Holding a piece of glass over rotating iron, stone, cork and felt was not the most exciting pastime. In order to hold my interest, I began grinding and polishing different thicknesses of glass with different angles. I bevelled flash glass, coloured glass, and textured glass and made a display case to carry around. This was in the days before the Internet, when artists walked around with large portfolios. I loved opening it up to clients, who instantly realised that I had something special to offer them.

Wayne taught himself to bevel on antique bevelling machines.

A wonderful thing about being self-taught is that one doesn’t know when to stop. I also developed bevelled glass windows with thicker glass so my windows would ‘hold their own’ when surrounded with oversized wood mouldings. Then it was on to UV-gluing beautiful, deep, rich colours of antique glass behind my bevels, giving them a jewel-like quality. This led to my contemporary bevelling style.

Carving, painting, and fusing soon followed. I loved the experimentation, being able to quickly test an idea by trial and error. When I look over my life’s work, the one thing that really stands out to me is the diversity of styles and techniques. I attribute this, in part, to how comfortable I am with dealing with the unknown and working with a variety of clients who have led me in different directions.

The studio makes commissions for clients across the USA.

Around 10 years ago, I began to renew my interest in the translucency of nature. I was also tired of wrapping each piece of glass in lead and foil, further restricting the light. I started introducing flame-working into my windows. I wanted to work in a painterly way, placing the flame-worked pieces onto the background glass and seeing how each piece of glass looked before permanently attaching the leaves and petals.

Wayne spent years perfecting his flameworking skills to add texture to his glass creations.

Flameworking was a slow, painful process to learn. If you count the time invested working over a flame, squeezing, mashing, and pulling a melting strip of glass, it was also a very expensive process. I know it took years of working in my spare time before I had the various shapes and colours, and a reasonable production time, to begin seeking commissions.

I remember showing a tour of 12-year-old students baskets of my flame-working rejects during a demonstration in my studio. For a second, I thought their eyeballs were going to fall into my collection.

With the ability to form delicate shapes and colours and to work in three dimensions, I was finally able to work in a way that I had envisioned 47 years before.

Our latest innovation is creating branches with wire and solder and attaching them to the branches in our window design, adding even more depth to our windows. Suspending leaves and petals out on the ‘branches’ gives a realism that has exceeded all our expectations.

Greater realism is achieved with building up the solder to form trunks and branches on windows.

It is very difficult making a living as an independent artist/craftsperson. Some days, I feel like a corporation reduced down to one individual. It’s not only the expertise that must be constantly developed, but also the peripheral skills, like marketing, selling, website development, purchasing materials, making presentations, taxes, insurance, social media, communication, organisational skills, and working with the people who help us produce our art.

In the early days, people were very secretive about their work: “Don’t take photographs of my work”; “You stole that idea from me”. Now, for the most part, we live in a world where people freely share their ideas. Maybe not their closest secrets, or their client list, but there is an enormous amount of material available to everyone. I am especially fond of YouTube and specialist social media groups where one can share an experience and people from all over the world respond.

The Internet has made it possible for people to commission us from all over America. Working with photographs, email, postal service, and freight companies, we rarely have to leave our studio. This is a far cry from the days when we lugged around large portfolios and glass samples to meet with people who didn’t understand why a commission window cost more than $49.00.

The team works collaboratively: Wayne Cain, John Williams, Scott Graninger and Will White (Wayne’s grandson).

In my shop, everyone has the power of influence. If someone has an idea, a quick study is made, and we all share our thoughts. It is the same process I learned when finishing my bedroom. Thinking and doing, trial and error. Every line, every colour is carefully considered. We take risks – a lot of them – always hoping to discover something new.

We never use the word ‘mistake’. Our brains move so rapidly: we just know if something is not right. We work intuitively. There are billions of neurons in this three-pound organ between our ears, processing information in milliseconds. It is the “control tower” of our being, providing split-second insight that we often call creativity.

Wayne Cain letting his creativity flow on a new design.

In my studio, we harness this gift by giving it the time and space needed to function with the least amount of interference. Insights that take flight into the conscious are quickly written down and later transferred to a large sheet of pattern paper. From there, they find their place in the many categories and flowcharts we use to organise our work.

All of us in the studio work the same way. I may be the only one taking notes, but I am constantly listening and encouraging the free flow of ideas that provide the basis of our creativity. It is also the reason why everyone here deserves the right to sign each of our creations.

Our working relationship has also given us a new language, one that is often unspoken, where thoughts are quickly communicated in many different ways. I often think of it as communicating in a negative space, like the negative space in a work of art: powerful once discovered.

I believe that working in this way is very human. This is the way we have evolved over thousands of years to manage a complicated, ever-changing world. It also accounts for our needs for diversity, community, and good communication skills.

The other trait I believe necessary to succeed as an artist/craftsperson is perseverance. There are certainly less difficult ways to make a living, and we are all too often seduced by easier jobs, higher pay, and benefits. But there is nothing as fulfilling as assuming responsibility for your own development, then making a living based on what makes you unique.

Remembering Harry Seager (1931-2021)

A tribute to the life and work of this influential architectural glass sculptor, by Keith Cummings.

The sad news of the death of the sculptor and teacher Harry Seager represents a great loss to all who knew him. He was an original, influential sculptor, teacher and mentor and, over an active working life of over 50 years, he touched many lives.

Although he used glass as a sculptural material in his glass and steel constructions some time before the studio glass movement was established, he provided an enduring example and benchmark for the generations of students who graduated from the glass courses which proliferated in his wake.

His pieces managed to be both monumental and playful at the same time. The sinuous, linear steel structures supported and shaped the precisely-cut glass sheets into rhythmic forms that belied their enormous weight and the great engineering expertise that went into them.

Born in Birmingham in 1931, Harry was initially drawn to science, but settled on art, and attended Birmingham School of Art to study sculpture. After college, and two years’ National Service, he began producing site-specific works for buildings in a variety of materials.

He became a lecturer at Stourbridge College of Art in 1961, teaching the new Fine Art course, and offering the new Diploma in Art and Design in 1967.

Harry started experimenting with sheet glass as a material in the early 1960s, drawing on the examples set by the Russian constructivists. Initially he used resins to bond sheets together, but graduated to complex steel armatures, which enabled works to be re-assembled and repaired.

He was represented by the Gimpel Fils gallery between the 1960s and the 1980s, which brought his work to an international audience, and much acclaim. He is also represented in many public and private collections, including the Victoria and Albert museum.

In his later years, he used glass more sparingly, working in a wide variety of materials and scales. He never lost his enthusiasm and love of life and people, which made him a delightful person to know.

He was busy in his studio to the end, leaving ambitious pieces unfinished when he was cut down by this cruel virus.

He loved his home and family and was married to his wife Marie for 58 years. He leaves her, their daughter Rebecca, and two grandchildren, Misty and Alice. Their beloved son Rueben pre-deceased him. He will be sorely missed by all who knew him.

Artists selected for Glass, Meet the Future 2021 film festival

Six art works exploring new ways of engaging with the materiality of glass in the digital era have been commissioned as part of the ‘Glass, Meet the Future’ (GMTF) film festival 2021.

The seven artists awarded are Alison Lowry and Jayne Cherry (Northern Ireland), Flora de Bechi (Scotland), Griet Beyaert (England), Juli Bolaños-Durman (Scotland/Costa Rica), Madeline Rile Smith (USA) and Simone Fezer (Germany).

Their contributions will form part of the core GMTF schedule alongside new film entries, a publication and podcast.

Unique in approach, each project has been selected for its resonance with core human emotions and the intangible relationship with the material of glass and film.

Alison Lowry and Jayne Cherry’s work will reflect on the numerous State- and religious-run institutions that operated in Ireland between the 18th and late 20th centuries, incarcerating mothers and their children. Their collaborative, site-responsive work will be a visceral experience, using a glasswork as the investment object to provide a cognitive dissonance for the viewer.

Flora de Bechi’s work, entitled ‘Glass into the mould, light into the camera, body into space’ is rooted in research and experiences gathered whilst on residency at North Lands Creative in 2019. The film features a poetic imagining of the hollow space of the Grey Cairns of Camster as both a camera and mould. A digital artist’s book will accompany the work.

Griet Beyaert’s ‘Remote Glass Sound Workshop’ will explore the question, ‘What do you hear when you think about the future?’ This will later be realised as a short film and glass sound piece using the collaborative soundbite submissions of participants.

Juli Bolaños-Durman will explore how the visceral bond between the maker, community and material permeates the creative process, guiding it to become something raw and precious at the same time. Juli is interested to explore human curiosity and the instinctual need to play and create.

A performance-based work by Madeline Rile Smith will highlight communal acts of creation and collective action involving hot glass and textile-inspired processes. This unspoken film will document a story of social currency, communal effort, and interpersonal connection in the glass studio.

The performance work will form a narrative exploring The universal existence of structures and the interaction of human beings with them, their similarities and differences, and the connectedness of everything, will be the narrative behind a performance work of Simone Fezer. It will focus on restriction, adaptation, reflection, perspectives, and the complex layering of reality.

Speaking about the artists’ work selected for GMTF 2021, Karen Phillips, Director of North Lands Creative, said, “The festival commissions feel genuinely human, different and empathetic. It’s this fighting spirit and determination from the artists to gain back some cohesion that we can all resonate with right now.

“We are following what is happening all over the world related to Covid-19 and the impact it has on artists, the arts, the cultural landscape and to life globally. With physical mobility still on pause, in response we see proposals for solidarity arising. The six key commissions chosen have deep-reaching, hard-hitting, topical themes at the heart of their projects, and a COVID-19-adjacent element.

“Proving that out of adversity comes creativity, Glass, Meet the Future 2021, hopes to invite dialogue, prompt questions, and drive analysis and contemplation of life and the world as we know it, the artists commissions will be particularly interesting in the festival’s second year given the unique challenges and limitations faced by all.

“We are delighted that we could provide artists with the opportunity to produce new work covering a range of geographical areas, approaches and audiences.”

Supported through British Council Scotland and Creative Scotland as part of the UK in Japan and working alongside North Lands Creative, GMTF 2021 will deliver a programme of physical and online events taking place internationally throughout the year. Project partners are the Toyama Institute of Glass Art with Toyama Glass Art Museum in Japan and the Museum of Arts and Design, New York.

Alongside the new commissioned work, GMTF 2021 will showcase a cross section of international diverse short films using glass as the predominant feature.

The Glass, Meet the Future Festival 2021 takes place from 20 March-4 April 2021, and continues in Japan in October 2021.

In memory of Sam Herman (1936-2020)

Leading glass artist and educator, Keith Cummings, pays tribute to one of the great innovators of the contemporary glass world.

Sam Herman, one of the major pioneers of the British Studio Glass movement, sadly died on 29 November 2020. As a maker, teacher and powerful apostle of hot glass forming, his influence on the development of the British Studio glass movement has been long lasting and truly revolutionary.

As one of the original students of Harvey Littleton’s glass course at the University of Madison-Wisconsin in the early 1960’s, he experienced first-hand the development of the small furnace at Wisconsin by Harvey Littleton and Dominic Labino. This allowed art students to actively shape the glass themselves, and to use glass as a genuinely creative studio material for the first time. It also placed glass in American colleges as a Fine Art material.

There were only a few courses in glass design at British art schools at this time, all of which saw glass as part of a strict design process in which students’ designs were realised by skilled, industrially trained craftsmen.

When Sam Herman came to Britain in 1966 (after graduating with a Master of Fine Arts in Sculpture and Glass), bringing with him an exhibition of glass work by Wisconsin students, his impact during visits to Edinburgh, Stourbridge, and the Royal College of Art demonstrated both a new way of making and a new way of seeing glass as a vehicle for creative education. His personal example, and his refreshingly direct way of talking about his work, set in motion the entire first wave of British studio glass makers, including Pauline Solven, Karlin Rushbrooke, and George Elliott.

He was invited to teach at the Royal College of Art, becoming head of the glass department from 1967 to 1974, during which time he led the first group of students who were able to work hot glass from the new, Wisconsin-style furnaces.

In 1969 he helped to establish the Glasshouse in London which provided glass studios for rent, and also as an outlet for their work. His joint exhibition in 1971, with the jeweller Gerda Flöckinger in the Victoria and Albert Museum, further established his growing global reputation and signalled that studio glass in Britain had come of age.

He worked and exhibited across the world during his long, rich and productive life and career.

He was always unmistakably American in his strong, direct approach to teaching and making; he never stopped experimenting and encouraged his students to do the same. He nevertheless chose to settle in Britain, and remained a lifelong presence.

The recent book about him, edited by Rollo Campbell, with a foreward by the Marquess of Queensberry, is a fitting testament to his life and work.

The evolution of 3D printed glass

Today, it is possible to 3D print everything from body parts to houses. But 3D printing of glass faces challenges, not least because of the high temperatures required to keep it fluid while the shape is extruded. Glass Network digital’s editor, Linda Banks, examines the progress that has been made in glass 3D printing in recent years.

In 2015 an Israeli startup, Micron3DP, was one of the first to successfully 3D print with glass in a hot liquid form. The company stated that it had managed to “print ‘soft’ glass at a temperature of 850 degrees, as well as borosilicate glass at a melting temperature of 1640 degrees Celsius”. It used “an extremely hot extruder” for the task.

Micron3DP was able to create accurate and unusual shapes with its extrusion process, which even led to a collaboration with Swarovski to 3D print its crystal glass. Swarovski were sponsors of the 2017 Designers of the Future awards and one of the winners, TAKT Project, used Micron3DP’s printing process to create a Printed Crystal series of candleholders and vases. The pieces, which were inspired by frost crystals, had fine, gently ribbed textures and a thickness of just 1.5mm. They were shown at the Design Miami/Basel exhibition 2017. See images of the vases in this article by Dezeen.

However, by 2018, Micron3DP had decided to shift its focus away from 3D printing of glass. In an interview with 3D Printing Media Network, the company’s CTO Eran Galor noted that the main challenge was to educate the market. He likened the problem to that faced by the development of fibreoptics in the 1980s, when “nobody knew what it would be useful for because the internet had not been invented yet”. In the case of 3D glass printing, he said, “We cannot clearly pinpoint the market yet, but it could become a huge opportunity.” He explained that engineers needed to understand how to design for 3D printing, which offered the opportunity to create a huge variety of unique shapes. He cited the company’s work with the University of Helsinki in Finland, during which they collaborated on the design of a complex microfluidic tool that they were able to print in less than 10 minutes.

While Micron3DP clearly believes there is potential for its glass printing technology, particularly for applications in the pharmaceutical industry, its commercialisation has been shelved for the time being.

Meanwhile, academia was also developing its own 3D print solution for glass. Teams from the US-based Massachusetts Institute of Technology’s (MIT) Mediated Matter group, Department of Mechanical Engineering and Glass Lab showed off G3DP, their own additive manufacturing process for 3D printing optically transparent glass, in 2017.

This featured a high-heat extrusion printer, fitted with two heated chambers. One contained the molten glass, and a ceramic print nozzle extruded the molten soda-lime glass into the second, annealing, chamber at a temperature of around 1000 degrees C. The second chamber was maintained at around 500 degrees C, just above the annealing temperature of the glass, until the printing of the design was complete. Then the chamber was cooled gradually.

The MIT team has since continued to refine its technology, with its G3DP2 platform combining a digitally integrated three-zone thermal control system with four-axis motion control.

In order to test its capabilities, a set of 3m-tall glass columns was created and shown at Milan Design Week in 2017. In the abstract for the article, ‘Additive Manufacturing of Transparent Glass Structures’, the authors stated that the project highlighted “the geometric complexity, accuracy, strength and transparency of 3D-printed glass at an architectural scale for the first time, and a critical step in utilizing the true structural capacity of the material”. Watch the printer in action and the creation of the beautiful glass towers in the video GLASS II via this link .

On a smaller scale, Australia-based Maple Glass Printing has been experimenting in the 3D glass printing field since 2017. The company’s CEO, Darren Feenstra, and CTO, Nick Birbilis, believed there was a gap in the market for a more affordable glass printer that would have a wide range of commercial applications. They decided to retrofit a polymer 3D printer to see if it could do the job.

It took two years of work and experimentation to create the preliminary prototype. They applied for a patent and received grant funding to commercialise their 3D printer towards the end of 2020.

According to Tony Koutsonikolas, Maple Glass’ Head of R&D, two important benefits of this printer are that it is able to use 100% recycled glass and that its processes are less energy intensive. The glass is only heated for a few minutes at high temperature to soften it. This means that the printer could help in the push to create a more sustainable society, as the company’s central mission is to reduce glass waste by 3D printing it for a second life. He points out that Australia alone uses 1.3 million tonnes of glass each year.

The team has focused on experimenting with recycled bottle glass, as one of the goals is to reduce the amount of such glass being sent to landfill. The problem has been that different types of glass melt at different temperatures, which means all the types have to be sorted, and they are difficult to reuse. Existing recycling processes currently require clean glass to be mixed with the bottle glass and energy usage is high. Maple Glass see their printer as a possible solution – a tool to process this ‘waste’ mixed glass, make new products and reduce the burden on the environment.

Currently the extruded glass layer height used by the printer is 1mm, but the plan is to reduce this in due course. This would enable the production of pieces with flatter surfaces. They could also be further smoothed, polished or drilled with a diamond-tipped tool once cooled.

Objects created so far have been a maximum of 150mm in height, but the hope is that the commercial version could create items even larger and in a range of colours.

As with other 3D printing technologies, printing time varies significantly depending on the size, shape and complexity of the item. A small perfume bottle, for example, may take one and a half hours to print, Tony explains.

He suggests another application for the 3D printer is as an enabling technology, offering a way for artists to create designs digitally and iterate versions easily. The company is open to discussions about innovative ways in which the printer could be used, so if you have an idea, look at their website and get in touch.

Tony is pleased to announce that the commercial version of their 3D printer for glass will be launched this month (January 2021) and you can read more about its technical specifications and possible applications here.

Perhaps the world is now ready to embrace the potential of 3D glass printing.
