Formulated for artistic ceramics, it is ideal for throwing and modelling smooth pieces with fine details. The high content of grog confers an excellent behaviour during drying and firing. Its particular ivory colour after firing is much appreciated and provides an excellent ware for glazes and colouring oxides, which develop bright and intense tones. Suitable for tableware (\u003cstrong\u003efood-safe\u003c\/strong\u003e), according to ISO 6486. Available in extruded body (moist form).\u003c\/p\u003e\u003cp\u003eFiring range recommended for the clay to develop its best performance, both in terms of technical and safety characteristics, under conventional firing conditions. The colour samples may show temperatures outside the recommended range to provide a broader view, but these are pieces fired under controlled conditions.
