White-grey porous material no. 19 is a special type of material which is characterised by its unique sintering properties when fired at 1100 °C (i.e. sintering 100 °C lower than ordinary stoneware). Due to this property, this clay (together with black-brown variant no. 12 and red-brown no. 18) is recommended for the production of utility ceramics using low-temperature glazes of the PD and PK series. Due to its light colour, the glazes stand out well on it, their colour is not distorted even with semi-transparent glazes. The quality of the clay as well as the packaging corresponds to the high standard of all German Witgert ceramic clay.

Witgert masses are well packed in a strong PE bag secured with an aluminium clip. 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.

Hmota je krásně plastická, děti ji mají jak modelínu, dobře se s ní pracuje.
