How to use Cupric Oxide powder in the ceramics? How to select the best CuO for your specific needs? The importance of Copper monoxide quality in the ceramic production process.


Copper Oxide is used in the production of enamels, coatings, and glazes, too. 

Black copper oxide (CuO) is a blackish-grey powder used as a colorant in the preparation of slips and glazes. It acts as a flux and produces fluid glazes. Black copper oxide can also be prepared as a wash and used for brushwork application to bisqueware. In oxidation, it typically produces greens, while its reduced form is red. Because it contains more copper than copper carbonate, copper oxide is more intense.

Copper Oxide - Uses in Pottery

How to use Cupric Oxide powder in ceramics?

Cupric oxide powder is a pigment used in the ceramic industry for imparting blue, green, or red tints in ceramics, glazes, and enamels. Under normal oxidizing conditions, the CuO molecule remains unchanged and produces clear green colors in oxidation glazes. Copper Oxide (II) is well-known for its ability to produce blood-red and fire-red colors in reduction atmosphere firings where it is altered to Cu2O. Cupric Oxide, also known as tenorite mineral, is used not only as a coloring agent in ceramics but also in the production of enamel frits to increase the adherence on surfaces. Moreover, it is a strong flux and even 2% can considerably increase the melt fluidity of a glaze.

The importance of Copper monoxide quality in the ceramic production process.

Black Copper Oxide powder quality plays a key role in the production process of ceramics. Carefully selected raw materials can guarantee a top-quality cupric oxide-free-flowing powder. In fact, copper monoxide (CuO) lots can have different technical specifications, grades, and particle sizes to satisfy the different needs in the production process of ceramics, glazes, and enamels. Arte Fo Ltd. distributes Black Copper Oxide in the standard packaging. For specific needs, we can supply custom-made packaging according to customers' requirements.
