This is a 10kg portion of slab-shaped raw clay that has been processed in a pug mill. 20kg portions are also available. This product is a brand of Shino clay, but it's not overly "rough" and is easy to shape. I make slightly more than 10kg, but the weight may be less than 10kg if moisture evaporates and the clay hardens. Wrap the clay directly in a wet towel, seal it in a plastic bag, and once it softens, weigh it before use. The color may appear slightly different depending on the lighting. I may use the same images for multiple listings, so the exact same item may not be delivered.
