soaprock การใช้

• The first porcelain potters to extract Soaprock from Mullion Cliff were Nicholas Crisp and John Sanders at their Vauxhall factory in London.
• In 1752 these cliffs were part of a quarry site from which the mineral soapstone, a talc, known then as soaprock, or steatite was extracted.
• Once removed from the cliffs, all the Soaprock was sorted, weighed and transported in wooden casks by sea to the primary early soft paste porcelain factories.
• In 1748 one of the first factories was set up in Bristol by potter Benjamin Lund who is named as the tenant on the first known Soaprock Lease.
• These included Penruddock Quarry, SE of the Vro Rock and the largest of all the soaprock quarries, that of Daroose, situated SE of the Vro.
• A further factory, also using soaprock was set up in Liverpool in 1756 by Richard Chaffers and Phillip Christian, and at Caughley in Shropshire about 1775 by Thomas Turner.
• Following Kynance Cove, a better quality and more easily accessible site for Soaprock, was discovered to the north at Gew Graze ( " Soapy Cove " ) in 1748.
• Soaprock was still being produced near to Predannack and Mullion and transported from Mullion Cove as late as 1815 from where it continued its journey to porcelain factories such as Worcester where it was still in use.
• "I had a background in geology, and one day I was in the shower and there were soap remains that looked like little pebbles, " said Tod Pink of Oneonta, N . Y ., recalling the moment when he conceived of Soaprocks.
• On the Martyn Map, ( which took him 10 15 years to Survey ), Kynance Cove is not identified by the name Kynance but merely by the words " The Soapey Rock " indicating that the Soaprock may have been removed from there by early porcelain potters prior to the currently accepted first use date of 1748.
