Letâs face it: Most of us don't give much thought to our pee before we flush it out of sight. But the basic details of your urine -- color, smell, and how often you go -- can give you a hint about whatâs going on inside your body. Pee is your bodyâs liquid waste, mainly made of water, salt, and chemicals called urea and uric acid. Your kidneys make it when they filter toxins and other bad stuff from your blood.
Further refining may be performed using one of two processes. In cementation, the acidic solution of copper is deposited on to scrap iron in an oxidation-reduction reaction. After sufficient amounts of copper have been plated, the copper is further refined using the pyrometallurgical process.
5. Mix a brown patina solution instead. This solution will turn your copper a darker brown, roughly the color of an American penny. Simply shake baking soda in a bottle of hot water one spoonful at a time, until additional baking soda does not dissolve.. Use tongs to dip the copper into the liver of sulfur solution for a second or two. Using gloves and tongs, or tweezers for small items, hold the copper under the surface of the liver of sulfur and water solution for a short time.
