Casting slips

The casting slips should have a weight of 1,8 kg per liter and should run down viscously from the finger, thus not drop. It is recommended to sieve the masses before use (sieve 52-72 mesh), in order to avoid contaminations, lumps or air bubbles. To increase the fitting of the glaze roughly 7% calcite (already contained in 23/WKFL and 23/WK) can be added to the casting slip relating to the amount of the dry-mass (= roughly 500g per bucket).

A brown-burning casting slip results from adding 2-5% manganese-dioxide to the red-burning mass.

For tiles and plates 20-50% chamottes can be added to the casting slips. In this case the castings slips have to be processed rather stiff in order to avoid a deposition of the chamottes.
