School blush no. 322 contains approx. 40% of 0-0.5mm size chamotte. This is the cheapest packaged material on our market, offering the best price for hobby workshops with a low budget. It is therefore suitable for beginner ceramists. Higher colour variations of individual production batches are allowed for this mass, as it is produced together with material for industrial customers. The quality of the clay as well as the packaging corresponds to the high standard of all German Witgert ceramic clays.

Witgert masses are well packed in a strong PE bag secured with an aluminium clasp. They can be easily transported and the clasp on the packaging can be re-closed with pliers when the required quantity is removed. Witgert ceramics are produced using wet or semi-dry technology (flakes). They are not made from dry powdered or granulated mixtures, which avoids the hardening that is common with such materials, which occurs after a certain period of storage even without breaking the packaging.

For long-term storage of our ceramic clays, we recommend placing them in a low-heated area (garage, basement, etc.) without the risk of freezing, put them in a black bag and tie them up. The absence of light will prevent the formation of mould. Stored in this way, the materials have a virtually unlimited shelf life.
