Basic knowlegde of Ceramic Pigments

[Rose Lin]

Generally speaking, Ceramic pigments consist of some combination of salts, metallic oxides, alumina, silica and natural clays. These different materials each convey different colors to the final pigment. A combination of zinc, chromite, cobalt and alumina, for instance, produces a blue-green pigment, with the ratio of chrome to cobalt allowing for a bluer or greener result. These mixtures exhibit more stability than oxides, natural coloring agents that can react with one another or with the heat of the kiln to spoil the intended result. An alcohol base serves as a solvent to keep the pigments from oxidizing.

The color pigment is made of the multi-purpose ceramic powder,Widely used in construction coating and glazed ceramic productsStable quality, Wide selection of colors. Pigments includes a mix of coloring and stabilizing agents such as metallic oxides, salts and other minerals.Ceramic objects fashioned from clay, glazed and fired in a kiln can take on a variety of colors through the addition of pigments.You can brush a ceramic pigment onto a completed pot or other object, or you can mix it directly into the clay or glaze. To ensure safety and achieve the desired results, you should always read the manufacturers' labels and note any temperature requirements or toxic ingredients.
