Info
Hawthorn Copper Sulphate Crystals can be used as a safer alternative to nitric acid for etching aluminium or zinc. Adding sodium chloride (table salt) enhances the etching solution’s performance and longevity.
To prepare a Saline Sulphate etch, mix 100g of copper sulphate with 100g of common salt in 1 litre of warm water. This solution is especially effective on zinc. Straw Hat Varnish can be used with copper sulphate for stopping out.
