Non-Toxic Printmaking
TAP printmaking studio uses Non Toxic inks and a Saline Sulphate Etching process,which is for etching zinc, aluminium, and mild steel and consists of a copper sulphate and sodium chloride mixture in equal parts.
This type of Metal Salt Etching System is free from harmful gas emissions. The chemical reaction by-products are contained within the etching solution without polluting the workshop atmosphere. It is safer because it is based on the principle of electrolysis: metal salts do not corrode metal through the destructive and harmful processes that typify acid etching: they owe their etching properties to electrical attraction in which atoms of the metal plate are elegantly removed by the metal compounds that are dissolved in a salt solution.
