To achieve our recommended thickness of enamel, put 8 parts by weight of wet process dry powder into a suitable sized container then add 3 parts by weight of boiling water and stir until smooth, leave it to cool down and it is then ready to use. If you prefer, you can vary the powder to water ratio to suit your requirements.
The photographs show the enamels applied direct to degreased copper by spraying. If spraying is used, efficient extraction must be used to remove spray vapour from the work area. The enamels can also be applied either by dipping or with a soft brush. Each photograph shows one and two coats of enamel.The gauge of the copper is 0.9. The actual size of each tile is 6cm x 10cm. Firing time was 3 minutes at 1472F. The copper groundcoat can be used to give an off-white base on which to apply wet process colours. Higher and longer firing of wet process enamels on copper gives very interesting results as the tile colours become tinted with chemicals in the copper base.
