Description:Wetmore Mill on Longton Road was used to grind flint and bone for the pottery industry. The addition of such materials to porcelain resulted in additional strength, whiteness and translucence. At one time there were ten flint mills in the Moddershall Valley.
Wetmore Mill was built in 1763 as a flint mill, and was briefly converted into a linseed oil and corn mill between 1821 and about 1841, before being converted back to flint grinding. The mill closed in about 1960, but the building still contains some of its machinery.
