How do I slipcast ceramics?

Slip

To slipcast a ceramic object we need so-called 'slip', which is liquid clay. Slip comes in various flavors, as do other clays: earthenware, midfire & stoneware. Slip is not just powdered clay thinned down with water, but rather a liquid clay with special additives. These additives, such as sodium silicate, keep the slip liquified with as little water content as possible. This has the effect that the slip will be fairly viscous after standing in the bucket for a while. After some vigorous stirring it will become quite thin.
