Graal Technique

In this course you can learn about the Graal Technique, a combination of hot and cold working techniques. Here participants’ own ideas, stories, decor or pictures can be cut into a prepared blank (consisting of clear glass with one or more layers of colored overlay glass), using sandblast, glass engraving and cutting. After cutting, the blanks are then re-heated, picked up, overlaid with clear glass and blown further into shapes by the glassblowers. These complex pieces involve all aspects of glass design and engineering and are a challenge to make.

This course is designed for everyone! Interested amateurs as well as glass artists from other disciplines are invited to take part. We look forward to an intensive week.
