Moss Agate

A variety of Art Glass developed by John Northwood (1836-1902) and Frederick Carder (1863- 1963) in England in the late 1880s. It was made by casing a parison of soda-lime glass with colorless lead glass, then covering it with powdered glass of several colors, and casing it again with lead glass. The object was shaped and reheated, after which cold water was injected into it, causing the soda-lime glass to develop a network of fine cracks.
