First I decide how the piece will be mounted, which impacts the design. I will either use a plaster hump mold or hand build the clay. Use of rails provide a even thickness of the clay. I have found this impacts both the firing and the final look of the product.
The first sintered method of pâte de verre uses glass the size of sugar and powder and is packed into a plaster-silica mold and kiln fired to a tack fuse texture known as sintered.
My second major exposure to Pâte de Verre was at The Studio in Corning, NY. If you ever get the chance to visit take a week as the collection held at Corning Museum and their library is world class. There’s nothing like seeing the pieces in person to put in perspective the beginning and progression of glass. It was there I first saw Henri Cros work, more on that later.
