How to make casts from plaster

Before you remove the forms, a model must be examined carefully, mentally divide into parts, then each piece of form was shot without effort. Imagine this distinction, and define auxiliary lines that stick figure snowman divided into three parts.

Put a pencil on the vertical lines that are barely noticeable. One line will divide the figure into two parts. Another line swipe from the side, it turns out that the third part of the "cut off".

Put the snowman on the table and from thin sheets cut into small strips. It is better to cut from the cans. Insert metal strips in the model for the already planned lines.

Prepare a spare block of clay, cut it into plates thin wire of the desired size. A figure draped all along the same lines plastic edging to make the fences of the required height.

Cover the rear half of the figures in one layer wet Newspapers so that the plaster does not stain when forming the other surface.

The side not covered with paper, brush with sunflower oil with a brush.

Now have to work with plaster. Take the rubber gipsovka and pour water to half capacity. Start to pour the gypsum, while the water appears a small bump. All this mix thoroughly. It turned out a plaster solution.

Working with plaster you need to quickly, otherwise it will harden. Spoon directly from gipsovki cover the surface of the figure bounded by metal plates. They will not allow the plaster to spread.

The form is solid, you need to make rebar. Will cut strips of wire and put on the first coat of plaster. And after, cover the figure with another layer of plaster. After 20 minutes it hardens and will need to remove the plate and paper.

With a sharp knife need to align the cut plane. Drill out the tip of a knife several small holes. They need to have the pieces match with each other. The remnants of the crumbs of plaster brush off with a brush.

All edges and plane oil sunflower oil. Cover the second part of the figures with a solution of gypsum. Before forming the second figure, insert metal plate at the lines, which had previously been delineated, and the surface cover with a wet paper.

Expand the form. With a knife gently posetite the connection lines. Disassembled into three parts, a figure of clay will remove plaster and clean. Now it is no longer needed, because we got a exact copy, only from plaster. A good dry form.

Dried disassembled form paint. Put in a warm place until the lacquer dried.

Two parts of the snowman fold together, fasten with a wire and carefully begin to pour into the solution of gypsum. An hour later, the plaster hardens and you two figures again to be separated. Inside get the exact figure of the snowman, which were fashioned from clay. Put the finished figure on the shelf that it is fully hardened.
