Note: As this is a natural product, the clay may develop a mould occasionally. This is perfectly natural and creates no issue for the clay or those handling it. Most experienced potters prefer their clay with mould as it increases plasticity.

Joining: Use a slip to join clay pieces. To make slip: Dried clay is crushed and mixed with water mix to a custard consistency. Keep in airtight container.

Storing and Handling Clay:
Always store clay out of direct sunlight and heat. Avoid poking fingers through bag. Never carry the clay bag by the heat seal this could cause moisture to escape from the bag. Between uses, store clay in a well-sealed soft plastic bag i.e. plastic garbage bag. Squeeze the air out of the bag and tie it in a knot. A small amount of moisture can be splashed into the bag to keep clay moist. If clay becomes too firm, slice slab / lump into 1cm thick slabs (like bread slices) and dip each one into water before placing them in a stack in a plastic bag. Sit for 1-2 days, then knead into shape. This is the fastest and easiest way to recycle.
