Pâte de Verre means "paste of glass" in French. The term originated in France at the end of the nineteenth century to describe a technique of glass making: a process of mixing colored glass powder with a special paste, charging it inside a mold, and firing the mold to melt the glass to obtain a cast glass work. A wax or clay model is made. The model is then covered with plaster and after it dries the wax is melted out of the mold with steam. Thus, the "lost wax method". The plaster mold is then charged or filled with glass and extra glass placed in a gate above. Then the mold is fired in the kiln. After firing the plaster is carefully removed from the glass and the glass piece is cleaned and polished.
