kiln casting optical glass
Glass casting by Anna Alsina Bardagi

Each optical glass sculpture is a unique creation which takes months to complete and involves several stages and techniques. From idea conception to mold making, pieces are fired in a kiln for over two weeks following a 14-stage temperature monitoring system to ensure uniform cooling.

Once the firing process is completed, pieces undergo multiple polishing stages to reach optical transparency. Kiln casting enables the creation of intricate shapes inside the glass, which are a result from melting glass into one single pure piece.

Sculptures are created using crystal clear, eco-optical glass by Ohara.
