Multicolour lustre
This class includes many styles of decoration and is typified by the Gloria Lustre range produced between 1923 and 1928. Many items are spectacular limited-edition exhibition pieces, but there are many too that were destined for a much more utilitarian function, despite the known difficulties of general wear and tear on the surface of this type of lustre.
Research suggests that the Gloria Lustre range started at number 2800 and finished at 7200. Within this range a rebus was often added to the marks under the pot and the footring was painted (see 'Designers, Gordon Forsyth' section).
