It communicates bright blue and green colours to the 

 flame of a candle, or if exposed to the blast of the blow- 

 pipe, it developes vapours of muriatic acid, and melts at last 

 into a globule of copper. It is soluble without efferves- 

 cence in nitric acid. It consists, according to PHOUST and 

 KLAPROTH, of 



Oxide of Copper 76-595 73-00.

It is chiefly brought from Chili and Peru, but is also 

 found in Europe, as in the repositories of Iron-ore at 

 Schwarzenberg in Saxony, and upon lava in the neigh- 

 bourhood of Mount Vesuvius. It is often produced when 

 metallic copper or copper-ores have been exposed to the 

 action of the atmosphere, or of sea-water.
