Coloring power of ceramic with glauconite admixtures

The possibility of using glauconite additives in the production of ceramics and their influence on the intensity of coloring of ceramics have been studied. It is shown that the effect of glauconite additives on the color of fired products depends on the composition of the clay, the amount of the additive, its specific surface area and the firing mode - the rate of temperature rise, maximum temperature, as well as the duration of firing.
