Spode reputedly bought William Turners Stoneware patent some time during the second decade of the Nineteenth Century, with items classed as stoneware appearing from around 1815. Experimentation with Felspar and other additions to the formula saw a patent for “New Stone” filed around 1821, with pieces primarily featuring oriental style designs appearing by the following year. When Copeland Garrett took over the factory in 1833, the mark was retained. Pieces of this style and with comparatively early pattern numbers like the one illustrated below fall into the early and original Spode New Stone era and this plate dates from around 1822-1825
