October 16, 2009, Newsletter Issue #366: Parabolic surfaced molds/wheel

Tip of the Week

Cool Trick! You can make a nice slump mold by centering a tub of plaster in its liquid stage on your wheel and spinning it at constant speed till it sets up. Spinning a liquid in a tub produces a parabolic surface and the faster it spins, the deeper the curvature is. If the speed is fast enough for the edge of the parabola to climb over the edge it will spill plaster all over the place! Try this with a tub of water until you are confident you won´t spill it over the edges.
