Aluminum spray coatings
I am using a low grade sheet aluminium as a framework for growing copper-sulphate crystals on. The sheet needs to be submerged in a warm saturated solution for a number of hours. Having tested a small amount of solution on the raw aluminium I am getting a pink corosion and impure crystals.
My thinking is that I need a waterproof lacquer of something clear. Any Suggestions...
