Copper Etching Solution - Pint

Also known as Ferric Chloride, Iron Chloride, and Iron Perchloride, this relatively safe, photo grade, neutral material is used to bite plates, including zinc and steel plates. Used solution may be beefed up by adding ferric chloride crystals, a spoon at a time, until no more will dissolve. Store solution that has been used on copper separately than solution used to etch zinc. Spent solution may not be used interchangeably. Not for use in aluminum trays.
