Training in working with borosilicate glass - 8 Thursdays

taught by Jörg Hanowski (D).

8 Thursdays, starts Th 13th October 2022

Borosilicate glass is also called hard glass, known for laboratory test tubes and pipettes and still better known for coffee and tea pots which can one minute be used to pour piping hot liquids and the next minute rinsed out under cold water without the glass breaking. Borosilicate glass has, in fact, a low coefficient of expansion and can survive these temperature differences. Because of this, working with borosilicate glass on the oxygen torch is a totally different experience than working with soft glass such as Moretti that can’t handle such wide temperature variations. Borosilicate glass has become known as “A Glass Maker’s Friend” because it doesn’t go flying past the side of your head so easily!

But borosilicate glass offers another challenge: the hollow tube!! Because of its use as a technical glass, borosilicate glass is available in a wide variety of diameters and thicknesses, all produced with scientific precision. Manipulating a glass tube at the torch actually requires completely different skills than for manipulating a solid glass rod. This course is focused on working with the tube and the goal is: a wine glass with a stem! And for the real go-getters: a perfect wine glass with a stem and decoration!!

Students will receive individual guidance during the course. As a result, the course is open to all enthusiasts regardless of their previous knowledge of torch techniques. The first 2 lessons are group lessons focused on working with solid rods. After that, students receive individual guidance and the more advanced students can shift to working with tubes. Simple animal figures are employed to learn techniques such as: “gathering glass”; “making connections”; “pulling points”; “blowing”; etc. At every step of the way, the objective is to achieve perfect results with attention to body posture, consistent dimensions and thickness, control over the glass, etc. Hereby is the level of perfection and complexity – at an individual level – increased more and more. How much a student learns during this course depends not only on their starting level and natural talent but is also highly dependent on the amount of time he or she devotes to practicing and doing homework assignments between classes. In other words: practice makes perfect!!!

Though trained as a technical glassblower, Jörg Hanowski has predominantly made his name in the art world. With his glass objects, including also neon installations, he’s pulled in numerous international glass awards. And further he regularly creates glass works for colleague-artists.

Fusing with float glass

Sa 12th and Su 13th November 2022


taught by Uschi Ullmann.

Fusing with float glass is a specialty within the glass fusing technique. Float glass, also known as window glass, is mainly available in clear. A number of products have been specifically developed for float glass to be able to add color to your projects such as powders, various sizes of frit granules, confetti, stringers, roundels and squares – and all of this in about 40 colors (opaque or transparent). Our teacher, Uschi Ullmann, co-developed these colored glass products and understands them like no one else. Because this glass requires a different design approach, the focus of this hands-on workshop will include designconsiderations, a departure from what Stipglas usually does. Under Uschi’s expert guidance you’ll explore the extensive possibilities this glass offers while you also learn about the technical aspects of this float-glass compatible color palette.

Uschi lives and works in Germany; she was trained at the Glasfachschule in Zwiesel (1977-1980) and besides German, speaks fluent English and Spanish.

Workshop hours: From 10:00 – 17:00 (registration is only possible for both days)

Level: From 1 (kiln technique)

Costs: EUR 250,- (includes glass and the use of necessary tools, lunch and taxes)

Location: Stipglas, Utrechtsestraat 6,Tilburg (The Netherlands)

Glass fusing - Basic skills

Sa 11th and Su 12th March 2023


taught by JanHein van Stiphout (NL).

This is a 2-day workshop focused on the melting and fusing of glass. It’s a technique whereby everything revolves around a single question: how does glass react at a high temperature?

Topics included cover:
- tack fusing
- full fusing
- the use of various colors of glass (transparent and opaque)
- the compatibility of different kinds of glass and how to test it
- the COE of different kinds of glass
- the calculation and reasoning behind heating and cooling schedules in the annealing kiln
- the movement and shifting of the glass and the effect of gravity
- devitrification and air bubbles
- using molds
- safety guidelines and information about fusing kilns and controllers.

The theory will be put into practice via practical exercises. This is a professional workshop aiming to teach skills rather than being focused on producing specific products. It’s appropriate for both beginners and those who already have some experience.

Level: From 0 (kiln technique).

Workshop hours: from 10:00 – 17:00 hrs

Costs: EUR 250.00, includes materials and the use of necessary tools, lunch and taxes

Location: Stipglas, Utrechtsestraat 6,Tilburg (The Netherlands)

Glass Beadmaking - introduction to working with hot glass

Sa 25th and Su 26th March 2023


taught by JanHein van Stiphout.

This workshop serves as an introduction to working with hot glass through bead making. To make glass beads, the glass is heated at a torch to over 1000°C. This makes the special experience of working with liquid glass accessible to everyone. How pliable is liquid glass? What is the effect of transparent vs. opaque glass? How can this technique be extended to applications other than bead making?

Topics include:
- Making round, conical and cylinder shaped beads.
- Building up a disc.
- Making and using stringers and twisters.
- Placing dots and raking glass.
- Making flowers and using murrini’s.

Hands-on practice will be supported by the necessary theory. This workshop aims to teach skills rather than being focused on producing specific products. It’s intended for beginners.

Level: From 0 (lampworking).

Workshop hours: from 10:00 – 17:00 (registration is only possible for both days)

Costs: EUR 210.00 (includes materials and the use of necessary tools, lunch and taxes)

Location: Stipglas, Utrechtsestraat 6,Tilburg (The Netherlands)

Sea shells

Su 2nd July 2023


taught by Michaela Maria Möller (G).

It’s also possible to blow glass at the torch using a mini blowpipe. This opens the door to a whole host of new design possibilities. During this workshop we’ll focus on making seashells, but with the blowpipe you can make, for example, multicolored shards. The technique for mixing colors will also be addressed during the workshop.
This workshop demands a reasonable level of control and skill at the torch. Oxygen torches connected to an oxygen tank will be used during the workshop. If a student would rather work with the Conkinect torch, that’s also possible. Michaela speaks also fluent English and understands Dutch.
