The Plymouth and Bristol factories, and (from 1782 to 1810) the New Hall (Staffordshire) factory under Richard Champion's patent, were producing hard paste similar to Oriental porcelain.The technique was developed by adding calcined bone to this glassy frit, for example in the productions of Bow porcelain works and Chelsea porcelain works, and this was carried on from at least the 1750s onwards.Josiah Spode I effectively finalised the formula, and appears to have been doing so between 17. The importance of his innovations has been disputed, being played down by Professor Sir Arthur Church in his English Porcelain, estimated practically by William Burton, and being very highly esteemed by Spode's contemporary Alexandre Brongniart, director of the Sèvres manufactory, in his Traité des Arts Céramiques, and by M. As the understanding of the work of the early potters depends in part on the study of actual specimens, the loss was both aesthetic and scientific.The business was carried on through his sons at Stoke until April 1833.
Thomas Minton, another Caughley-trained engraver, also supplied copper plates to Spode until he opened his own factory in Stoke-on-Trent in 1796.
The colour paste was worked into the cut areas of the copper plate and wiped from the uncut surfaces, and then printed by passing through rollers.
These designs, including edge-patterns which had to be manipulated in sections, were cut out using scissors and applied to the biscuit-fired ware (using a white fabric), itself prepared with a gum solution.
Today Spode is owned by Portmeirion Group, a pottery and homewares company based in Stoke-on-Trent.
Many items in Spode's Blue Italian and Woodland ranges are made at Portmeirion Group's factory in Stoke-on-Trent.
