Nice Fit

Process video of Tobias and I vacuum forming three different objects multiple times: a spoon, a milk bottle and a bowl. The bottoms of the latter two were previously cast in alginate, then plaster positives were made from the alginate molds. The spoon is partially embedded in a board of MDF. In some scenes a rubber layer is added over the plaster to scale the overall size; in others a previous plastic vacuum form was re-vacuum formed (as in a copy of a copy, and even a copy of a copy of a copy). All forming was done with a thermoset sheet of ~1mm polystyrene.

Of note: plaster is naturally porous and easily vacuum forms while a plastic shape does not. Also: for enlargements with indentations, the rubber must be punctured with a pin or small drill bit.
