[QUOTE="Pat Hogen, post: 482093, member: 11720"] Safety instructions from mamasminerals.com should not go astray: Only use chemicals that are clearly labeled and store them in a secure area away from pets and children. Keep a large container of clear water handy to wash off any chemical spills. ALWAYS wear safety goggles & rubber gloves. Don't work alone. Avoid splattering. Never pour water into acid -- always add acid to water. Keep an ample supply of baking soda handy for acid spills. Keep an ample supply of vinegar for alkali spills. Rinse specimens well. Too much oxalic acid can turn quartz yellow, so if you have light staining, only use about 2 tablespoons of oxalic acid per 1/2 gallon of water. Always remember to add acid to water, not water to acid! Let your mineral specimens soak for one to several days, or, if you're in a hurry (or the staining is very heavy), you can heat the solution by standing the bucket in the hot sun. Some people use an old crock pot instead of a plastic bucket, and heat their acid solution that way. Don't heat this solution on your kitchen stove, and don't use any kind of metal container. Do this procedure outside, particularly if you heat (never boil) the acid, as it puts off poisonous fumes. Oxalic acid is mild as acids go, but rubber gloves are a good idea when handling either the acid solution or your specimens until they are well rinsed. ... [/QUOTE]
