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.
