It is characterised by high whiteness, translucency and strength. Production usually involves a two stage firing where the first, bisque, is without a glaze at 1280 °C (2336 °F), which gives a translucent product and then glaze, or glost, fired at a lower temperature below 1080 °C (1976 °F).

English manufacturers were keen to produce porcelain of the quality to be found in Chinese imports, but they had to go down a different route.The first use of bone ash in ceramics is attributed to Thomas Frye in 1748 to make a type of soft-paste porcelain, at his "Bow China Works" [ [http://www.british-history.ac.uk/report.asp?compid=22166 'Industries: Pottery: Bow porcelain', A History of the County of Middlesex: Volume 2: General; Ashford, East Bedfont with Hatton, Feltham, Hampton with Hampton Wick, Hanworth, Laleham, Littleton (1911), pp. 146-50] accessed: 18 November 2006] . In the late 18th century, Josiah Spode undertook further developments, and subsequently popularised it, by mixing it with kaolin and China stone to compete with the imported Oriental porcelain.
