Slipcasting
When slip is poured into a mould made of gypsum plaster, water molecules in the clay body start to move past other components and into the pores of the gypsum plaster via capillary action. The other solid components, however, are too big to enter the pores and are deposited at the surface of the mould. A clay skin layer gradually builds up, conforming to the inner shape and contours of the mould. The longer the slip is held in the mould, the thicker the ware.
Rayn’s quest to perfect his glazes entailed innumerable tests. Needing to create a multitude of test pieces quickly and efficiently, he turned to slipcasting as his forming technique.
What began as a practical need transformed into a means of fulfilling his artistic vision. As a potter who started on the wheel, Rayn is able to break from making round forms using the slipcasting technique.
