Glass

Glass is a very special material. The Egyptians and Romans manufactured it many thousands of years ago. Glass is a composition mainly of sand and soda. When the composition is heated it becomes glass.
Glass has special properties.
It is very hard but at the same time fragile. Therefore it is hard to imagine that you can create and realise your design in glass.

If glass is heated from room-temperature up to over 1000° its properties gradually change from hard substance, through a molten rubber-like substance, to a liquid.
When the heating process is halted the glass freezes in the state it was when the heating stopped.

These properties make the glass very suitable for:

• Fusing and slumping and
• Glass blowing.

The starting-point for these operations are reversed.
Glass blowing needs liquid glass “hot-glass”, but fusing and slumping needs “cold-glass” to start the process (plates, powder, grains, bars etc.).

To reduce tension in the glass, it is necessary to cool-down the glass in a controlled way.

The aim of these workshops is to give you the skills required for fusing and slumping.

In the “Glaswerkstatt” you can take the an introductory course as well as the workshops.
