Instruction
1
Start with fabrication of a sculptural sketch of clay. This is the model on which you will create a plaster product. Plasticine is a soft material and can change shape easily. Knead it in your hands, and then formed into the desired shape. Work on a smooth Board, which should be several times wider than your future product.
2
With a knife mark on the clay line, which will be the connector shape. Press along the lines of the pieces of foil or baking parchment. Doing it carefully not to damage the shape of the product. The push foil and parchment hands, and the back of a pencil or pen.
3
Prepare a lubricant that will help to separate the form from the casting. Grease can serve as emulsion consisting of soap, cooking oil and water, mixed in the ratio 2:1:7, taken in the mass. As a lubricant you can also use a solution of stearin or paraffin wax in kerosene. Apply grease to the piece of clay.
4
Mix the plaster: dilute it with water to a concentration of not too thick sour cream. Cover them with a clay layer of a few millimeters. Apply the solution with a brush or flat spatula. Avoid formation of bubbles.
5
Apply several layers of plaster for added strength. Remember that the next layer should be put after hardening previous.
6
Remove the plaster mold when the product is finally cured. It will occur not earlier than half an hour after work. The more layers you applied, the longer it takes to dry plaster. To check whether the dry form, by tapping on it. The finished product will sound.
7
Correct small imperfections with a knife or sandpaper. On the inner side fill it with furniture varnish. Ready plaster sculpture can become an independent work or used as molds for casting other products.
