K37 Black Brick Stain

Ceramic Application

K37 is a custom-designed, black brick stain for your ceramic surfaces. Colour can range from a dark brown to a rich black, depending on your requirements. This beautiful black clay can then be used for bricks, pavers, roof tiles, and other ceramics.

  • Creating a range of colours from one pigment allows you to meet the needs of a wider consumer selection without purchasing additional products
  • Produces brown, matte black, jet black, pure black, rich black, and more
  • K37 can be used in all terra cotta brown red clays at temperatures of +1130°C



Milled to 98% below 45 micron / 325 mesh, which provides great surface area for consistent colour saturation.

Six percent to 12% addition, depending on the iron content of your clay.

African Pegmatite also offers K37B, which has a lower firing temperature of 1080°C. K37B is finding favour in Spain and other areas that have unstable clays at higher firing temperatures.
