Inquiry (采购产品): Hydrometer I need a small hydrometer to measure water content in glazes at the clay studio. WhenI say small i mean something less than the 13 inch long one that I have seen, so that I can measure small quantities. Do you have one and how soon can I get it? i am in Philly in the Old City at the Clay Studio on n. Second and could probably pick it up.
