Gypsum is a convenient and flexible material, as well as an easy-to-process material, and due to this, it is widely used in creativity, sculpture and even in interior modeling. It is not difficult to make a plaster figure of any shape if you master the technology of creating prints and removing plaster forms from them. If you want to make an animal figurine, shape it in separate sections, after dividing the figure made from clay as a temporary sample into them.
Instructions
Step 1
Mark the clay figurine into sections with the tip of a knife, drawing dividing lines - the midline of the back and abdomen, the front and rear edges of the limbs, as well as the inner parts of the body. When the figure is divided into separate areas, separate them mechanically - stick strips of thin tin or brass foil along the contours of the drawn lines. The strips should be 5x7 cm in size and fit snugly together.
Step 2
Dilute the liquid plaster according to the instructions, and then fill the areas in sequence - from large to small, from bottom to top. When the whole figure is filled with the first layer of gypsum 1 cm thick, wait for the first layer to dry, and then fill the figure with the second layer, diluted more thickly.
Step 3
Sand the edges of the beads of the individual pieces of plaster to determine where the metal boundaries are between the pieces and apply another coat, reinforcing the shape with metal reinforcement if it is large and heavy. Wait until all layers of plaster have hardened completely and then remove the metal partitions.
Step 4
Disassemble the parts of the figure by inserting a spatula or wedges into the gaps between the fill fragments, and then disassemble the resulting parts of the figure. Check the inside of the plaster molds for voids and holes, and if there are, coat them with liquid plaster, then sand.
Step 5
Clean the molds from dust and dirt, treat with nitro varnish to make the mold waterproof, and then coat the mold from the inside with a special lubricant that will create a greasy film that makes it easy to separate the impression from the mold.
Step 6
Now you can assemble the mold and pour plaster into it to get a finished impression that fully matches the mold with which you took the impression.
