This is a new extra white soft earthenware clay, especially formulated for hand and foot imprints.
Before using, clay should be kneaded to ensure that the moisture content is even and to expel any air bubbles. Avoid using the clay straight from the bag, as this can result in warping and cracking as there could be inconsistencies of softer and harder clay.
