Firing in kilns
The plaster blocks thus prepared are placed in a kiln for 10 days. Inside, the groisil melts and flows into all the smallest nooks and crannies of the mold. No two pieces are identical, because the fragments of groisil blend and merge at will as the crystal melts.
Once cooled, the plaster mold is carefully broken, to reveal the sculpture in pâte-de-cristal.
