Stop adding the copper oxide when it's in excess - in other words when the black powder doesn't disappear anymore. This means there is no remaining sulfuric acid to react.

It uses copper thermite to fuse radio ground rods to the copper ground cable. DX Engineering sells it – pretty cheap, about $8 per shot. Comes with a crucible to go over the ground rod and slots ...

Copper is found in many household items, such as jewelry, bowls, pots, and utensils. Over time, though, the surrounding air causes the metal to develop a layer of copper oxide, which makes it look ...

Scientists have developed copper oxide nanoparticles which can be coated onto implanted medical devices to reduce the risk of infection after operations. A team at Nottingham Trent University has ...
