Engobes for ceramic bricks

To expand the color gamut of the front surface of the brick, the engobing method was used. To control the color, a light-colored engobe composition was developed using red-burning clays, followed by coloring with the addition of various pigments. The rheological properties of engobe slip have been studied and the amount of electrolytes has been optimized. Il. 1, bibliography: 3 titles.
