Sculptural Slumping Masterclass Part 1

Lisa Pettibone, Surrey GU5 9LL
2-4 October 3-4 students, £425
This course is aimed at intermediate/experienced kiln-formed glassmakers exploring a variety of ways to control movement in the kiln with a variety of props and programming techniques. Students with minimal or no slumping experience will gain insights into novel glass forming processes. We’ll achieve this through a series of demos, visual presentations (explaining my own processes and other artists work) and two making projects. There will be creative prompts to investigate their sculptural ideas and why movement is so important in their work.

Working with both float and Bullseye glass, three kiln prop-making techniques will be explained so you can learn how to make your own: ceramic slip cast props (like store bought slumpers but your own design); hardened fibre blanket forms; moulded or carved refractory props. Extensive course notes with sample firing programs are provided along with all mould-making materials – students bring their own glass. Please email Lisa if you have further queries.

Lisa has been teaching kiln formed glass techniques for over 20 years at venues such as The Glass Hub in Somerset, the international Festival of Glass and Pilchuck Glass School in Washington, USA. She has a BA in Glass from University of the Creative Arts Farnham and an MA Art and Science at Central Saint Martins London. She has exhibited in the UK and internationally and is a member of the Royal Society of Sculptors.

Sand Casting Glass workshop

Description
Sand casting in glass is an incredibly creative and exhilarating experience.

Dive into the world of sand casting in glass—an unmatched opportunity for both beginners and seasoned artists. During this intensive glass casting day, you will design and craft three stunning glass pieces that you can proudly take home after a three-day cooling process in the kiln.

Your artistic adventure begins in the morning as you design and create sand moulds using a vibrant array of forms, shapes, and colours. Embrace your creativity and boldly incorporate metals and other unique elements into your designs. After a savoury lunch break, prepare to be captivated as you work with molten glass at a remarkable temperature of 1,150 degrees, straight from the furnace.

As you pour the liquid glass into your expertly crafted moulds, watch in awe as your vision transforms into breathtaking, one-of-a-kind glass artworks. You have the freedom to add vibrant colours, sparkling metals, and even delicate leaves between the layers, ensuring that the possibilities are truly endless. The results will undoubtedly inspire you, offering an extraordinary chance to immerse yourself in innovative glasscraft.

Rebecca Arday – From Life: Casting with Alginate – 7th, 14th, 21st, 28th July 2026

This is a live online class, taught over Zoom.

Learn to use alginate, an eco-friendly, affordable mould-making material, to create sculptural glass castings from life. Rebecca will demonstrate hand casting with the bucket method and face casting with the lay-up technique. You’ll create wax positives, refine them, and cast them into glass using a plaster-silica refractory mould.

Course price: £190.00

Learn to use alginate, a seaweed based, eco-friendly, skin-safe, economical mold making material, to create sculptural glass castings from life. Two styles of molds will be demonstrated: a bucket mold where the model is submerged (i.e., a hand), and a lay-up mold, where alginate is painted on and reinforced with plaster bandage (i.e., the face).

Alginate molds will then be used for creation of wax positives which can be manipulated if desired and ultimately cast into glass in a plaster-silica refractory mold. The course will cover the process from start to finish.

Join us for an in-person masterclass with Helen Slater Stokes at Morley College London in Summer 2026.
Over four days, you’ll explore a range of techniques for incorporating imagery into glass, from creating screen-printed stencils to producing your own decals. You will develop and apply these skills across multiple glass projects throughout the masterclass.
Course price: £850.00

What you will learn
Over four days, Helen will guide you through Spatial Imagery in Glass, exploring multiple approaches to developing imagery and translating it into kiln-formed glass. This masterclass is designed to expand both technical skills and creative thinking, offering participants a rich toolkit for incorporating imagery into their own practice.

You will explore a wide range of techniques, including glass sgraffito frit drawing, paper-cut stencil enamel printing, photo silkscreen enamel printing, and personalised decal transfers.

Helen will also provide in-depth instruction on screen-printing equipment and processes, including choosing appropriate silkscreens for different image types, correct squeegee handling, and working with liquid underglaze enamels.

Prior to the masterclass, participants will have the opportunity to prepare imagery for digital decals, which will then be incorporated into kiln-formed glass blocks during the course. Additional areas of focus include efficient kiln packing for tiles and blocks, embedding sgraffito frit drawings into larger works, and polishing finished pieces using minimal equipment.

This intensive masterclass offers a unique opportunity to develop technically advanced glasswork within a supportive and inspiring learning environment.

British Biennale Press Release

Glass Art Society Announces Artists for the 2026 British Glass Biennale Flagship exhibition

28 August – October 2026, at The World of Glass, St. Helens

The British Glass Biennale is back in 2026 as part of the International Festival of Glass, presenting a diverse range of works from both established and emerging glass artists working across the UK.

Organised by the Glass Art Society (GAS), the British Glass Biennale has been a flagship exhibition within the glass art world for over 20 years, and is the largest selling event of contemporary glass art. Showcasing artists from across the UK, it attracts an international audience looking to discover contemporary developments within glass art, both in technique and subject matter.

‘The British Glass Biennale is a highlight of the glass art calendar’ says GAS Executive Director, Brandi Clark. ‘The exhibition provides an opportunity for both established artists, and those who are at the start of their artistic careers, to share their works and ideas with a national and international audience. It is a fantastic opportunity to learn about new techniques and concepts being explored by contemporary glass artists.’

Artists taking part in the British Glass Biennale were selected from almost 400 applications by a panel of jurors. Alongside international jurors Tami Landis and Jeff Sarmiento, was British glass artist Louis Thompson. With over 30 years experience in glass art, as well as a former winner of the Biennale Best in Show award, Louis, alongside his fellow jurors, brought a wealth of experience and knowledge to the panel.

Commenting on the process, Louis explained ‘The task of any juror is never easy. I was impressed by the diversity and volume of submissions, the standard of work was high in all disciplines and
demonstrated richness, depth, and the quality of British glass today. Working with my fellow jurors, we discussed, debated and expressed our views before agreeing to the final selection. The selected artists engage in a visual dialogue, creating a landscape, which showcases intent, skilland conceptual understanding.’

Artists selected to exhibit their work in the Biennale include Alison Kinnaird, Colin Reid, Phillipa Candy, Camilla Bridgewater, Bruno Romanelli, and Jeff Zimmer.

Opening to the public on Friday 28th August at The World of Glass, St Helens, UK, the exhibition will run until the end of October 2026.
A further two exhibitions are held as part of the International Festival of Glass and will run alongside the British Glass Biennale – the International GAS Member Exhibition, and the
International Bead and Jewellery Exhibition. A full list of selected artists will be available on the GAS website.

As the largest selling exhibition of contemporary glass in the UK, and with almost 200 artists represented across all three exhibitions, collectors, visitors, curators, and anyone with an interest in glass art will be able to see a range of styles, methods, and concepts from some of the leading glass artists working today.
