07 Carving Wax Nº 5

Carving wax balls are made and molded for designing the jointing for the doll. The molds may be made from hot-melt moulage, water saturated plaster, or silicone rubber. Click on any image to enlarge it.

This is an old photo of a plastic knob being used as a model and molded in plaster. It is easy to see the spare. The spoon was used to carve the registration keys in the first half of the mold, prior to the second half of the mold being poured. Plaster sticks to plaster, so a parting agent must be used between the two halves of the mold, otherwise the mold would be a one piece mold.

This is a moulage mold for making carving wax balls, showing three of the carving wax balls that were cast. The cast carving wax balls are welded to the doll parts using a wax pen.

One way of making the ball models to mold is to use a turning box.

Another way to make ball models is to combine cereal box cardboard into a spherical armature, then fill it in with clay or wax.
