Clams to Cash: How to Make and Sell Giant Clam Shell ProductsPage 10Caution: If you are not very careful with this method, you can easily destroya shell by leaving it in the acid dip too long. Be careful not to damage thelovely glossy surface of the concave inside of the shell; if the gloss is gone,you’ve overdone the acid dip. Under no circumstances should a shell be leftindefinitely in the acid dip. It will get smaller and smaller and, eventually,disappear entirely.After the acid dip and the fresh water rinse, lay the perfectly clean shells in a plastictray to dry .
