SIO-2® Berlin Gray Stoneware High Fire Ceramic Clay Body, 4 lb Sample
Grey stoneware clay with 40% impalpable grog 0-0.2 mm (up to 80 Mesh). 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. Depending on the firing temperature, it develops an interesting range of greys, from cement to dark grey, which satisfies the most avant-garde trends in artistic ceramics. Suitable for tableware (food-safe), according to ISO 6486.

The AP Seal identifies art materials that are safe and certified in a toxicological evaluation by a medical expert to contain no materials in sufficient quantities to be toxic or injurious to humans, including children, or to cause acute or chronic health problems. Children in grade six and lower, and adults who may not be able to read and understand safety labeling should use only non-toxic materials. The AP Seal ensures products are non-toxic when used as intended for young children, the physically or mentally handicapped, and any persons who cannot read or understand the safety labeling on product packages.
“Food Safe” is a regulation and is defined by the Compliance Policy Guide, which is maintained by the FDA and only applies to lead and cadmium release. For example, “Food Safe” may refer to a glaze in its final, fired state. If a product has a food safe designation, it has gone through testing and passed industry standards for food safety when used according manufacturer’s direction. Finishedware producers bear responsibility for food safe testing their ware being sold into commerce.
