Chromium oxide is a versatile ceramic pigment, widely used to create deep and vibrant green tones in glazes and engobes. Its chemical stability allows it to retain color even in high temperature firings, making it a reliable and durable colorant.
In addition to intense greens, chromium oxide can produce pink or reddish hues when combined with other components and under specific firing atmospheres, extending its decorative range.
In traditional ceramics, such as Islamic earthenware, it is appreciated for its bright and permanent green tones, which have been part of its distinctive aesthetics over the centuries.
Interesting Fact
Its use extends beyond ceramics; it is also a key component in the abrasives industry and is used to polish metals and gems due to its hardness. In addition, it is the base pigment for the well-known "chrome green", a color widely used in artistic painting and road signs due to its high stability and resistance to light and weathering.
Helpful Tip
Use chromium oxide in small quantities, as it is a strong pigment. Keep in mind that it can generate different colors depending on the kiln atmosphere, so testing is key to control the final result.
