The history of clay mining
They rose in fashion and fetched high prices at market. Demand was sky high and they quickly became a status symbol for the lords and ladies across Britain who liked to display them in glass fronted cabinets in their dining rooms.
William Cookworthy, a Plymouth chemist, knew that if he could find a source of kaolin in the UK he would be sitting on a white gold mine. He set out testing the whole country and he finally found deposits of the same standard as the Chinese kaolin at Tregonning Hill, near Helston and then later in St Austell. The deposits just north of St Austell were the largest deposits in the world and as work began to extract it, the Cornish market exploded.
