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. In 1751 the newly formed "Worcester Tonquin Factory" set up by Dr John Wall, William Davis, Richard Holdship and 12 other Directors adopted the soft paste porcelain formula and early in 1752 purchased the Lund pottery and acquired the Lease for Gew Graze. In the same year, 1751, Nicholas Crisp and John Sanders opened a porcelain factory in London at Vauxhall. 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. The last well known factory was set up in 1813 in South Wales at Nantgarw with the arrival of William Billingsley, but by this time Bone China was beginning to be developed at other Factories and was becoming the ceramic of choice. 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.
