Etching

There is no evidence that the Vikings knew how to etch metal, but the results are very similar to the other techniques. Consequently, etched fittings are acceptable, as they bring the relief working technique into the hands of almost everyone. This should only be undertaken by those with suitable training and supervision due to etching requiring potentially dangerous processes.

Sketch out your design on the work and paint the design on with a thin paint brush, remembering that the painted items will be untouched by the etching fluid, but the unpainted areas will be eaten away, i.e. they will be areas of low relief.

The depth of etching will depend on how long the etching fluid is in contact with the metal – a few hours should suffice. Do not leave the fluid on the metal too long, or it will eat its way right through! Finally rinse the etching fluid off the work and flush with running water to purge the metal of the etching fluid. Decorate and polish as required.
