A matte, zinc base glaze. Transparent, matte glazes often look good with a faint colouring of colour stains or on top of slips. If 1004 is laid on top of decorative paints, we recommend doing it on a white clay then possibly "milk shadows" do not become as clear.

The glaze powder is mixed with water, for good mixing results we recommend glaze stirrers [325031]. Measure approx. 8 dl water per kg glaze powder and slowly pour the powder into the water while stirring. Adjust glaze powder and amount of water using a hydrometer [324060]. If the glaze has not been used for some time, the specific gravity should be checked before use.

We recommend that transparent and single-colored glazes should be sieved through a sieve with a mesh density of 60 mesh [32522060], however, sieving of effect glazes should be avoided.

The glaze can settle, to avoid this adjusting agent ABM-3 [2858] can be added.
