Our range of transparent Jewellery enamels are designed for use on tombac (gilding metal), copper, gold and silver.
The guilloche pattern is a reproduction of a type of metal engraving that was popular at the turn of the 20th Century.
The copper blanks are a standard grade of copper.
The samples were prepared by wet packing, firing time 2 minutes at a temperature of 800° centigrade. The enamels are supplied in powder form, ground to pass a 60s mesh (250 micron) sieve.
Colour descriptions are based on the fired trials on silver.
