CIRCA 1910 signed A Walter Nancy and H Bergé SC 22.5 cm long Almeric Walter was born in Sèvres in 1870 and is famous for his work in pâte-de-verre glass. His father and grandfather were ceramic artists . He received lengthy art training which provided him with a solid understanding of model and mold making, painting, and enameling. Pâte-de-verre works were produced by Ancient Egyptian and Roman glassmakers, prior to the first century AD. At its simplest, the process includes filling a refractory mould with granules of glass, heating the glass in a kiln until the grains fuse into a single mass, cooling and breaking away the mould, followed by cleaning and selective polishing of the glass. The benefit of this method is that colors can be specifically placed within the mould, creating elaborate decorative coloring. The difficulties of the process are numerous; mould breakdown, imprecise temperature control, unwanted color flow, gaps in the fused glass, inability to view glass during firing due to mould, destruction of mould during firing process, and difficult color placement in a three-dimensional mould. Walter developed a glass paste with a high level of lead, which created a softer glass which fired at a lower temperature. This was ground into a very fine paste and painted on the inside of the mould before filing and firing.
