The UK is largely self-sufficient in gypsum. The material can be found in seams in the Pennines and the Midlands, but the biggest source of extraction is in East Sussex where mining extracts some 100,000 tonnes of gypsum a year from 100 m below the High Weald. The mined rock is reduced to powder through a process of crushing and grinding.
