Glass Art Sculpture the making of a Bernard Katz Glass design from start to finish. A behind the scenes view from our glass studio in Philadelphia.
Bernard and I decide on the perfect colors to use for our glass sculptures. There are many colors to choose from opaque to glass powders.
Bernard works with two skilled assistants to create the piece within our glassblowing studio. The hot glass process of sculpting each piece can take up to an hour. Due to the extreme high temperatures, the piece must stay up to temperature, otherwise the sculpture may break.
The glass sculpture is slowly brought down to a room temperature for several days in an annealing oven.
Once the piece is at room temperature, Bernard can grind the clear glass button off the end of the piece and bring to a high polish. (the button is where the piece was attached to the glass punty)
Bernard sandblasts the transparent part of the glass sculpture, which gives the piece a gorgeous smooth “frosted” texture. The sandblasted part is carefully coated with a sealer called “liquid luster.”
From start to finish, a glass sculpture can take several weeks to complete.
The final results are rather spectacular! As shown below from our Melange Collection in Cerulean Blue the Bolinas Sculpture.
