Anti-gloss product, applied on the glaze surface before firing, creates extremely fine, random topography at the glaze surface without significantly changing surface roughness. The topography causes light to be scattered along with all directions equally. The result is the prevention of higher glossiness, i.e. the shiny appearance of matt glaze surfaces, at high angles to the normal. This effect is achievable at a very small amount of applications ( ≈3 g/m2 on a solid basis).
