Coade Stone lion on Westminster bridge


A brand name for a cast stone made from fired clay. Coade Stone was developed by Eleanor and George Coade in England and manufactured from 1769 to 1840. Analysis indicates the raw materials were Ball clay from Dorset or Devon with the addition of 5-10% Flint, 5-10% Quartz sand, at least 10% Grog, and about 10% soda-lime-silica glass (Freestone et al 1984). These Terracotta cast stones were used for interior and exterior ornamental elements. Coade Stone is acid resistant and weathers well. It was used for statues, tombs, balustrades, vases, pillars, and decorative architectural elements. One large example is the Coade Stone lion on the south side of Westminster Bridge.
