Hi Rhona, Go to your hardware or Home Depot and buy a gallon jug or two of Muriatic acid. I try to buy mine at the Habitat for Humanity Restore. Their prices are always a half of everyone elses. Get a couple of small to medium plastic tubs with snap on lids. Have at least surgical gloves available, but the longer dishwashing type are better. I use water/acid on a one to one ratio. Read the instructions on the jug re: do you pour acid in to water, or vice-versa. It will keep you out of trouble remembering it. Fill the acid bath about half way with the mix. Put your pieces of pottery in the dip. Fill it with pieces until there isn't any more room to cover the pottery w/ liquid. Now, just let then sit for 2-3 days. with the lid snapped shut. Sunlight degregates acid strength. The other tub is a dip bath of water, after you haul the pieces out of the acid bath. Obviously, if you can do this all outside, the better. I do it near an open window with a fan running- no big deal. Try to have a tarp or plastic down, as the acid will stain whatever it hits. Then, wash each edge of the pottery with dishsoap and a toothbrush. Works for me. Bill
