Inquiry (采购产品): Nitric acid Friends have told me that I need nitric acid to clean copper/native rock specimens from the UP of Michigan. Please tell me of a local supplier in the Twin Cities of MN where I could obtain one gallon. Thanks much!! **** Hidden Message ***** Thomas House 55112 Company: None E-mail: tchouse44@comcast.net **** Hidden Message ***** tchouse44@comcast.net
