The perfect product if individual bricks with a special surface are to be used. These melting colours produce both changing colour effects and a variety of surface textures, creating unique effects which are especially suitable for producing rustic, rough surfaces on facing bricks. Melting colours GRONAT®-S are fine-grained grades with a particle size of up to approx. 3 mm. GRONAT®-ES are relatively coarsegrained products with a particle size of approx. 5 mm. They create a particularly rustic effect by forming small irregularities in the brick. Melting colours GRONAT®-S and GRONAT®-ES can also be mixed together or with sand to achieve completely individual effects. Combinations with glazes GRONAT®, special engobes ENGOSYN® and tarnishing colours REDOX® increase creative options still further.
