White ceramic clay weighs 1 kg. Ceramic Paste can dry with air. It dries spontaneously away from the sun and heat source. You can knead it by slightly wetting your hand. Do not spill water on it. If you wish, professional baking can be done in industrial ovens (biscuit firing at 950-1050 degrees). If there will be water and food contact, professional baking is required. Product weight may be 10 grams more or less. You can store the ceramic clay you do not use in its own ziplock bag. When the product content of natural ceramic clay is first opened, the package appears dark gray. After the product dries, it turns into a very light gray-off-white color. Natural white ceramic muds are not completely white like other chemically white ceramic muds. After the product dries, you can paint and varnish it in any color you want without applying white primer.
