The firm began in 1793 when Thomas Minton (1765–1836) founded his pottery factory in Stoke-upon-Trent, Staffordshire, England as "Thomas Minton and Sons", producing earthenware. He formed a partnership, Minton & Poulson, c.1796, with Joseph Poulson who made bone china from c.1798 in his new near-by china pottery. When Poulson died in 1808, Minton carried on alone, using Poulson's pottery for china until 1816. He built a new china pottery in 1824. No very early earthenware is marked, and perhaps a good deal of it was made for other potters. On the other hand, some very early factory records survive in the Minton Archive, which is much more complete than those of most Staffordshire firms, and the early porcelain is marked with pattern numbers, which can be tied to the surviving pattern-books.
