Masterclass: Lost Wax Without Wax – Advanced Glass Casting – Antonis Koutouzis

Explore the possibilities of the lost wax technique without the need of wax.
In the lost wax process, we often deal with approximate 2-3% wax shrinkage of the model to be cast, plus additional time for retouching seamlines and any imperfections resulting from pouring/brushing into the mother moulds. The inevitable steaming of the wax can, furthermore, stress and weaken refractory moulds, especially in larger projects.

On this five-day advanced glass casting Masterclass, Antonis will guide you through a complex multistep process of creating positive and negative forms in silicone to eliminate these problems, resulting in a cleaner, more efficient, and more accurate realisation of almost any shape for casting.

Fusing Discovery Day with Amanda Mires

7th May 2026 (Thursday) Duration: 1 day

Location CGUK studio – Rochester, Kent

A compact class to delight and inspire all – from the novice to the artist investigating the set-up of their own kiln-working studio. On this enjoyable one-day workshop you will not only gain a better understanding of glass in general, but also expand your knowledge-base of all the firing processes. It’s the perfect class for those who would like to have a little more insight into what happens to glass behind the closed kiln door and how the firing program affects the end result. You will explore:

Selecting materials & tools
Combining exciting mixtures of materials
Firing techniques for perfect results
Adapting processes to suit your needs
Expressing yourself through your work

Our aim is to present reliable techniques in a relaxed atmosphere, so that you gain confidence with firings and discover your true creative potential. At the same time more complex issues such as compatibility, viscosity and annealing will also be covered, enabling you to build up a solid foundation for all your future glasswork.

Our resident teacher, Amanda Mires will provide a class which will include demos, lectures, written documentation, plenty of hands-on-work and, last but not least – a lot of fun for everybody involved – book now for a class that really delivers!

Projects
A set of small dishes / candle holders
A selection of samples exploring different techniques and firing temperatures

Skill Level
No previous experience required

Please note, places for this class are limited to ensure plenty of support can be offered to each attendee.

NB. A waiting list will be in operation once the class is FULL – please email info@creativeglassshop.co.uk if you would like to be added.

Kiln-Formed Glass: The Sustainable Art of Repurposing with Julia Gonyou

23-24 April 2026 (Thursday-Friday)

9.30am-4.30pm 2 days

Location: CGUK Glass Studio – Rochester, Kent

Please join us for an environmentally conscious new workshop focused on exploring the possibilities of sustainable kiln-formed glass, using recycled glass bottles, and float glass.

Participants will learn how to break down these materials and artistically repurpose the glass – without the use of moulds – into unique compositions using pattern, shape and script. You will explore techniques using expressive mark-making, textural objects and cut-outs to create distinctive relief work.

Explore this more streamlined and Eco-friendly approach to glass-making while building practical skills and creative confidence to support your future work.

Projects
Students will have the opportunity to create 3-4 projects, including sun-catchers, and free-standing panels to take home/collect after final firing.

Skill Level
Beginner/Intermediate

Further Information

Scratching the Surface: Engraved Glass Art with Julia Gonyou

21-22 May 2026 (Thursday-Friday)

9.30am-4.30pm 2 days

Location: CGUK Glass Studio – Rochester, Kent

Join us for an exciting new workshop focused on glass engraving. During the 2-day class, participants will investigate various approaches to sandblasting and engraving with rotary tools, both on clear and coloured glass. Students are welcome to bring in their own drawings but will also have access to a selection of studies to use as stencils, while being encouraged to experiment with expressive patterns and textures.

We will experiment with various ways to achieve our designs through using scalpels to cut through rigid resists and brushes to apply fluid resists. We will examine tonal variation by engraving to varying depths, free-hand sandblasting, and layering engravings. Participants will also work with a range of rotary tool heads to achieve more refined, drawing-like effects.

Develop practical skills, expand your technical understanding, and discover new creative possibilities within engraved glass!

Projects
Students will have the opportunity to create 1 main piece to take home, plus several experimental 10×15 samplers, home-made flashed glass, engrave a 3D object if desired.

Skill Level
Beginner/Intermediate

9.30am-4.30pm 2 days

Location: CGUK Glass Studio – Rochester, Kent

This engaging 2-day workshop offers a structured introduction to the leaded lights technique. Participants will learn the fundamental and artistic architectural processes involved in constructing stained glass panels, including designing, drafting, leading, soldering and cementing. The class will also highlight the purpose and importance of these specialised materials and procedures and why they are essential to the craft.

Students will have access to a selection of patterns and will be encouraged to integrate their own creative ideas with guidance from Julia. A variety of coloured and textured glass, along with different lead sizes, will be provided to support and enhance your compositions.

Although the primary focus will be the lead came technique, participants will also create two small kiln-fired sections, embellished with ColorLine paint, to incorporate into their hanging or free-standing panel.

This workshop provides a solid foundation in traditional techniques while supporting creative development and a sense of technical freedom to carry forward into future work.

Projects

A hanging or free-standing leaded stained glass panel, with the opportunity to incorporate 2 small painted kiln-fired details.

Skill Level
