Application of copper oxide as colorant in glass, enamel and ceramics

Copper oxide in the glass is mainly used as a colorant to change the color of the glass, in the process of making glass, the copper oxide can be added to the glass to change the color of the glass, most of which can become blue-green.
For example, in the production of some art glass or decorative glass, different shades of blue-green glass can be obtained by controlling the amount of copper oxide. The blue-green glass after adding copper oxide can increase the artistic sense and uniqueness of the building, and can produce rich light and shadow effects under different lighting conditions. Such glass is often used in the facade glass of some large commercial buildings. Usually, the vases we use to grow flowers will also have different colors, and copper oxide is also used as a colorant to make colorful and textural vases.
In the process of enamel making, enamel glaze is the key part. When copper oxide is added to the enamel glaze, it will have a physical and chemical reaction with other components in the glaze during the firing process, and it will show different colors.
For example, the bowls and plates we use most every day, the reason why there are different colors and color styles is also a hint of vitality given by copper oxide, and the color fixing effect of copper ions is very good and very popular.
Similarly, in the process of ceramic production, adding copper oxide to the ceramic embryo body, at high temperature firing, copper oxide will undergo a series of physical and chemical changes, will make the ceramic show different color changes.
Like ceramic vases, floor tiles and all kinds of ceramic artworks, the reason why they can show different colors, copper oxide is not small.
In short, copper oxide as a colorant, in glass, enamel, ceramics has a great contribution, and I believe that we will dig more uses of copper oxide in the future.
