The basis of Electro-etching - a simplified explanation
By Alfonso Crujera and Bob Perkin
Electro-etching, or galv-etch, is an electrical etching technique which can be practised conveniently and safely at home without the need for expensive equipment. This article presents some of the underlying ideas and terminology connected with electro-etching. It is not crucial to understand these principles in order to produce successful etchings. However, we believe that by presenting a simplified explanation, it may remove some of the mystery of the technique and assist in encouraging its wider use.
