The 19th-century French master Gabriel Argy-Rousseau (1885-1953) created glassware using the rare pâte-de-verre technique, which means “glass paste” in French. This is a rare and time-consuming technique, known in ancient Egypt. The essence of the method is that glass of different colors, crushed into crumbs or to a state of powder, is mixed with a small amount of a binder (for example, water, gelatin or glue), placed in a mold in accordance with the intended design and sintered in an oven.
