Copper Patina How to Patina Copper Patina Color

WebAzurite is very popular mineral among collectors. Bright blue pieces are polished into cabochon s and beads, and large masses are sometimes cut into ornamental objects. "Azure-malachite" is also carved as cabochons and beads. Azurite was formerly crushed and used as a blue pigment. Azurite is also an ore of copper. WebAzurite is a secondary mineral that usually forms when carbon-dioxide-laden waters descend into the Earth and react with subsurface copper ores. The carbonic acid of these waters dissolves small amounts of copper from the ore. The dissolved copper is transported with the water until it reaches a new geochemical environment. someflower lisshttp://www.gemcoach.com/azurite-guide/ small business obligations
