Description
 

Copper Oxide Black 10 Pounds


COPPER OXIDE BLACK -  (CuO) RED (Cu2O)  (m.p. 2100o F/1149o C) are the
two stable forms of Copper Oxide.  Both forms are coarser in particle
size than Copper Carbonate (also see Copper Carbonate).  The more common
of the two forms (in a glaze) is copper black (2%-5%).  It is a strong
flux used as a colorant to produce greens in oxidation and reds in
reduction.  Red Copper Oxide can be precipitated during reduction
firings as a component of a copper red glaze finish.  Other colors are
turquoise in Soda based glazes, yellow-greens in Potash, and blue-greens
in Barium.  Copper Carbonate can be substituted for Oxide if the amount
is doubled.
