John Wall, William Davis, and Richard and Josiah Holdship, signed a deed of partnership to produce porcelain.
British, mid 20th century, ivory plates with wide scrolling acanthus leaves and neoclassical gilt borders, marked in overglaze "Royal Worcester, Bone China, Made in England, Embassy", some with impressed marks and letter codes, 10-1/2 in...painted these were drilled for making into lamps. Its products include dinnerware, giftware, cookware, porcelain, glassware, collectables, jewelry, linens, curtains and lighting.
Hard paste porcelain is made of 2 ingredients-kaolin(clay) and petuntse(decomposed granite).
European countries were unable to unlock the secret to the formula so they made their first porcelains by substituting different materials. The soapstone made the porcelain withstand the heat of boiling water and produced tea services that were very much in demand.
Early production was rather haphazard and the purchase of Benjamin Lund’s Bristol company was used to bring vital technical expertise into the mix.
Worcester also obtained licences to mine soapstone in Cornwall and worcester soapstone porcelain did not crack when boiling water was poured into it; giving worcester a significant advantage over other producers.
