There are areas that were used for thickening the clay: settling pits, with a sloping floor, where the clay settled for several days until it had about 12% solids; settling tanks, where the clay reached about 30% solids in two to three months; the pan kiln, or "dry", where clay was heated from below

The museum is set in 26 acres (11 ha) of ground, and is based around two former china clay works. A large collection of objects, machinery, photographs and other archive material is preserved. It was established as a charity in 1975, with John
