Potbank
A potbank is a colloquially name for a pottery factory in North Staffordshire used to make bone china, earthenware and sanitaryware.
Etymology
The term potbank has been used for generations it is believed that it derives from Josiah Wedgwood who was unable to meet the demand for his creamwares. He sub-contracted other potters to make shapes to his specification, and to hold these in stocks until he required them. Their warehouses were called banks.[1]
Process
The raw materials of pottery include clay, quartz and feldspar. These are mixed sieved and filtered to make slip, which is pressed to make a workable body. Bowls are jolleyed on a wheel, plates are jiggered on a wheel and fancies moulded in plaster moulds. This greenware is dried, and placed into saggars which are stacked into a bottle oven for the first or biscuit) firing at 1,000C. The resulting "biscuit ware" can be decorated with an underglaze transfer and coated with a glaze. These are then placed in a saggar with kiln furniture thimbles to separate them and fired for a second time, the glost firing can be up to 1,400C, in another bottle oven. Depending on ware, the item could be decorated and gilded by hand and be fired for a third time in a muffle kiln at 1,250.[2][3]
Stoke-on-Trent
The six towns of the Potteries were the centre of the ceramic industry in the United Kingdom. The Trent and Mersey Canal which opened in 1777 provided cheap transport for the china clay from Cornwall, the bones and the coal from local colleries, and a smooth passage to Liverpool to export the finished goods.
