Cradle remove

a_cyclcradleremove

The first half of plaster is finished. Now I flip it over and remove the cradle. The front-side plaster now serves as the cradle for the work.

The cradle is removed in pieces and carefully pulled back from the clay blanket which remains in place against the plaster and surrounding the model. Toss out the cradle thankfully, for the work it did.

The second side is ready to begin working on. Another clay blanket and plaster will be made to enclose this side of the model.

Front plaster

Mold release is liberally applied to the clay and insides of the box. I use a aerosol spray-on product made from halogenated hydrocarbons in ether, well-worth the money for it’s effectiveness and ease of use. The plaster is poured, shaped and formed over the clay blanket. Doing this deserves some more photos, but I am too involved to stop and take them. Mixing plaster and applying it is a skill I have only begun to get at all proficient. This is about 1.5 to 2 inches thick, about right, could be thinner.

Removing the foamcore box, I trim and smooth out the plaster with a palette knife. It is mostly pointless, but I can reduced the volume of the plaster shell a little, and anyway, it makes it look nice and feel better to handle.

Now it should cure for least several days to a week. The plaster continues to dry out and get stronger. I want to wait to separate the assembled three layers- plaster, clay blanket, and model, from the cradle, which will be the next step. Removing the cradle will put pressure on the plaster and I want to be sure it is as strong as it needs to be so it doesn’t crack.
