Definitions for "Soft Paste"
A variation of true hard-paste porcelain, fired at a lower temperature and with different ingredients but producing a superficially similar end product. This term has, for years, been misused by collectors and dealers to describe creamware and pearlware.
A clay and ground glass mixture used to produce china. It's fired to a temperature too low to create the hardness of porcelain.
Eighteenth century first attempts at recreating hard paste porcelain produced in France and England. It fired up to 1150°C, and was made with silica (powdered glass) instead of petuntse.
