Porcelain wares have been produced following the directions contained in the Heylyn and Frye patent of 1744, using Cherokee clay and a lime‐alkali glass frit. The wares were fired to the bisque ( ̃ 950°C), glazed using a clay‐glass mixture, and then fired to a “heat‐work” level of Orton cone 9–90° deflection at 150°C per hour (1279°C). Modal mineralogy comprises Caplagioclase and two glass phases, one relict frit and the other a melt phase. The bulk chemistry of the body comprises 64.3 wt % SiO 2 , 21.7 wt % Al 2 O 3 , and 5.6 wt % CaO. Molecular ratios are SiO 2 :Al 2 O 3 5.0 and SiO 2 :CaO 10.7. It is concluded that the patent, whose significance has been questioned over many years, was a practical working recipe, that close comparison may be made with porcelains of the “A”‐marked group, and that the patent represents a remarkable landmark in English ceramic history. © 2004 Wiley Periodicals, Inc
