After exploring metal and marble, this object is his first to deal with glass. Instead of taking the obvious path of blowing, he decided to cast it. This technique gives the glass a density akin to natural stone while at the same time contradicting the transparency and lightness we have come to associate with it.
The process of moulding used for this piece is similar to the lost mould technique used in bronze casting. A reinforced plaster mould containing glass tiles is placed in the oven and heated. During baking, the glass melts into the mould. After cooling down, the plaster is broken and removed to reveal the glass form.
During the baking process, the plaster subtly cracks due to the heat. The glass flows into these cracks, the remainder of which is still visible in the final glass object, as a witness of the making.
