Introduction

This is the first of a short series in which I hope to entice enamellers to try their enamelling art on thin sheets of copper shim (0.06 - 0.15mm). I will list what is needed to get started in this introductory part and go on to suggest how the technique might be used for pictures and brooches etc.

The sparkle and variety of colour tone that can be captured by light reflected from a flat or worked metal surface, seen through various depths of transparent enamel is the basis of many enamelling techniques. Underlying undulations in the metal equally enhances the options and effects. Engraving and etching involve actually cutting into the surface, but repoussé and chasing demand pressing or punching depressions in the metal.

Repoussé (from the French "pousser" - to push out).

This is done by forcing the metal up from the underside, and possibly then working it alternately from both sides. This is usually done by hand applied pressure onto thinnish sheet. Chasing more often refers to hammering punches into heavier sheet (often 20 gauge and supported in pitch).

Applicable References

These techniques are mentioned in several enamelling books, with a specific article on using copper shim in the Book of Enamelling Techniques by Peter Wolfe & Gudde Skyrme (available from Camden Workshops).
