The yellow-coloured stoneware no. 14 sf contains 25 % yellowish chamotte of size 0 - 0,5 mm. This material is unique for its exclusive yellow colour. The higher it is fired, the more intense the yellow colour. Another advantage is that the glaze stands out well on a shard of this colour. Because of its chamotte content and its other properties, it is suitable for the production of medium-sized products and for ballasting techniques. For larger products we also offer this material in the 14 sf 40 fireclay version (40% fireclay 0 -0.5 mm). 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 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 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.
