| Description: | China clay workings, Great Pit, Lee Moor, south Dartmoor. General view across china clay-pit showing settling pits, covered conveyor belt for waste sand disposal, and (in distance) exploratory drilling rigs. Distance across pit approximately one mile. China Clay extraction originated in the mid-eighteenth century to provide raw material for the pottery industry. Recently most china clay is extracted for the paper industry which uses china clay as a filler and a coating pigment for high gloss products. Production of china clay at Lee Moor was recorded as 381,000 tonnes in 1969-70. China clay was first identified as a product at Tregonning Hill in west Cornwall between 1745 and 1748. The chief producing areas are the Hensbarrow area near St. Austell and south-west Devon. Lee Moor is in the latter. |
