Technique

Glass Triangle makes kilnformed glass. We do not blow glass. For the most part we work with glass when it is cold and then heat it in a kiln or oven. We use sheets of colored glass as well as glass powders and frit. Frit is glass that has been broken into pieces. The smallest size frit that we use looks like colored granulated sugar.

 

 

Our dishware is fused and slumped. Barbara assembles sheets of glass and decorates them with powders, frits, and stringers. Stringers are small pieces of glass that have been shaped while hot to make them look like lines and curves. The assembled glass is then fused together in the kiln to make a flat tile. That tile is then placed over a mold inside a kiln and heated until it collapses or slumps into the mold, taking its shape.

 

 

Kiln-casting glass means melting cold glass into a mold. Barbara sculpts a piece and then makes a mold of it with a special plaster that can withstand the heat of the kiln. She fills that mold with glass frit or larger pieces of glass and melts the glass in a kiln until it takes the shape of the mold. Once she has carefully cooled the glass, she breaks off the mold and cleans and polishes the piece.
