Soft Paste Porcelain: Early European Attempts to Replicate Chinese Porcelain
Soft paste porcelain is an artificial porcelain body developed by European potters in the late 17th and 18th centuries as they sought to replicate the true hard paste porcelain imported from China. Made from white clay mixed with ground glass (frit), bone ash, or soapstone rather than kaolin and petuntse, soft paste has a warmer, creamier appearance and softer glaze than its hard paste counterpart. The great early European factories -- Rouen, Saint-Cloud, Chantilly, Vincennes/Sevres, Bow, Chelsea, Derby, and Worcester -- all began with soft paste formulas.
Identification & Characteristics
Soft paste porcelain can be distinguished from hard paste by several physical properties. It feels warmer to the touch and has a slightly granular fracture when chipped, compared to the glassy, shell-like fracture of hard paste. The glaze sits on top of the body rather than fusing with it, often pooling in crevices with a greenish tint. When held to a light, soft paste shows a warm, creamy translucency versus the cold, blue-white light of hard paste. Enamel colors tend to sink into the soft glaze, creating a softer, more integrated appearance. An unglazed foot rim often feels gritty or sandy.

Condition Factors
Soft paste is more fragile than hard paste and more susceptible to staining due to its porous body. Chips and cracks are common in 18th-century pieces and should be expected. Restoration is widespread; examine under ultraviolet light to detect repairs and repainting. Firing cracks from the original manufacture are not uncommon and are accepted by collectors when clearly original. Discoloration from centuries of use (tea staining in cups, for example) is typical. The soft glaze wears more easily than hard paste, so check for scratching on plates and flatware.
Collecting Tips
Learning to distinguish soft paste from hard paste is the essential first skill for any porcelain collector. Handle as many documented examples as possible in museums and at specialist dealers. The warm, tactile quality of soft paste has always attracted devoted collectors who prefer it to the harder, more clinical feel of true porcelain. Focus on a single factory initially to develop your eye. Chelsea gold anchor, Bow, and Derby pieces offer the most opportunities at auction. Sevres soft paste commands the highest prices and the most rigorous connoisseurship. Be aware that 19th-century Samson of Paris reproduced many 18th-century soft paste styles; their copies can fool the unwary but are distinguishable by body composition and mark details.
