ETCHING
Ferricc chloride is a standard ferric sulphate, muratic,photoghraphic fixer,etc. If it were me I would try a small amount every inch or so it will be easy to compare the results. I use bee's wax to mask off items. make sure you apply your acides or salts with a cheap paint brush. Also make sure you nutralize it after. some just use soap and water afterwards. you can also use baking soda if paranoid. I would not glass bead anything unless you want to lose crisp edges and detail work.
