Glass structures

The wide variety of glass structures constructed from Puzzle bowls is proof that the combination of excellent manufacturing and an original idea can lead to brand new creations. So far, we have seen a very special rock garden, a unique structure built at the event marking the 6th anniversary of the Y Institute and Christmas decorations created by florists. Still to come is a glass pyramid 3 m in height, the largest to date.

Our challenge to you is to create your own structure and publish the picture on our Facebook page.
