Messrs Spode were succeeded in the same business in c.Although the Bow porcelain factory, Chelsea porcelain factory, Royal Worcester and Royal Crown Derby factories had, before Spode, established a proportion of about 40–45 per cent calcined bone in the formula as standard, it was Spode who first abandoned the practice of calcining or fritting the bone with some of the other ingredients, and used the simple mixture of bone ash, china stone and kaolin, which since his time set the basic recipe of bone china.
The bone porcelains, especially those of Spode, Minton, Davenport and Coalport, eventually established the standards for soft-paste porcelain which were later (after 1800) maintained widely.Blue underglaze transfer became a standard feature of Staffordshire pottery.Spode also used on-glaze transfers for other wares.with the introduction of underglaze blue transfer printing on earthenware in 1783–84.The Worcester and Caughley factories had commenced transfer printing underglaze and over glaze on porcelain in the early 1750s, and from 1756 overglaze printing was also applied to earthenware and stoneware.
