Note 29 — Chapter III · (continued 2)

“Mr. Billingsley, at the Nantgarrow manufactory, from Lynn sand, potash, and other components, made a porcelain which, as an artificial felspar, has some excellence, and approaches nearest real felspar; the expense certainly was great; and only was his ware defective through his being unacquainted with the principles of combinative potency. This was a notable instance how much the mechanical processes of pottery are in advance of the ‘work and labour of love’ for public benefit—the science of chemistry in regard to atoms.”—Shaw’s Chemistry of Pottery, 1837.
