Product Description
1kg (2.2lb.) copper etchant. Ammonium Persulphate crystals are used as an alternative to traditional ferric chloride to produce a cleaner copper etchant solution. 1 kilogram of crystals produces 4 litres of etching solution. Excellent for situations where the visibility of the etching process is beneficial (instructional use).
