8 Fridays from 11:00 - 18:00;
start: December 13th 2019

taught by Jörg Hanowski (G).

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!!!

Sa 8th Februari 2020

taught by JanHein van Stiphout.

With the use of a blowing mandrel, a hollow bead can be made even bigger and lighter than with the traditional method by “blowing out” the bead. Learning how to distribute the glass properly is critical. The ability to make hollow beads is a prerequisite for participation in this workshop. Otherwise registration for the January 12th workshop is required.

Workshop hours: from 10:00 – 17:00

Costs: EUR 140.00 (includes blowing mandrel, materials and the use of necessary tools, lunch and taxes); EUR 225,00 combination of Su 12th Januari and Sa 8th Februari 2020.

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

Sa 1st and Su 2nd Febr 2020

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.

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

Costs: EUR 190.00 (includes materials and the use of necessary tools, lunch and taxes)

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

Su 12th Januari 2020

taught by JanHein van Stiphout.

This workshop focuses on making hollow beads using the traditional method of building up from two discs. Hollow beads are significantly lighter than solid glass beads and as a result often preferable for using in necklaces and earrings.

As an artist, JanHein van Stiphout works with multiple glass techniques. For more information on his work see: www.janheinvanstiphout.com.

Workshop hours: from 10:00 – 17:00

Costs: EUR 95.00 (includes blowing mandrel, materials and the use of necessary tools, lunch and taxes); EUR 225,00 combination of Su 12th Januari and Sa 8th Februari 2020

Always wanted to learn glassblowing but never had the chance? Seize this opportunity to try it out and see if this technique is something for you. During the 2-day workshop students learn the basic techniques of glass blowing.
STIPGLAS regularly organizes “Work Days Glassblowing” throughout the year for students to practice independently. For more information, see the menu item 'others' on the left.

Workshop hours: 2 days: 10:00 – 17:00 (registration is only possible for both days)

Costs: EUR 190,00; includes glass and the use of necessary tools, lunch and taxes.

Sa 7th and Sa 14th September 2019

taught by JanHein van Stiphout.

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: 0 and higher (kilntechnique)

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

Costs: EUR 240.00 (includes materials and the use of necessary tools, lunch and taxes)

Sa 19th and Su 20st September 2019

taught by Michaela Maria Möller.

Bead making is an enjoyable starting point for manipulating soft glass at a torch. You have a steady grasp on the mandrel. But more is possible within lampworking. For example, forming sculptural pieces (3-D figures) or making semifinished products for further use in a fusing project. For such applications a mandrel can’t be used.
During Flower Power 1, Michaela Möller guides her students toward working off-mandrel with the first step being the assembly technique. For this technique we don’t abandon the mandrel completely. The individual parts that are made completely off-mandrel are put back together with the help of a mandrel into – in this case – flowers. Attention is also given to mixing colors and to pulling multicolor stringers. Level 1 and above.

Michaela Maria Moller was trained at the Glasfachschule in Rheinbach (G) and the Akademie für Gestaltende Handwerke in Aachen (G). She works in several glass techniques and exhibits regurlarly in Europe and the USA. More info about her work at: www.glassart-m.com.
