Sculpting can be fun. Plasticine is very convenient for this. It consists of clay, dyes, wax, oils (for example, petroleum jelly) and other additives that prevent the clay from drying out and losing its plastic properties. Since plasticine is very sensitive to heat and softens easily in warm hands, when exposed to direct sunlight, being near a radiator or at a hot temperature in the room, it is an urgent task to securely fix the results of the sculpting labor.
Instructions
Step 1
Place the clay periodically in a cold place, such as in the refrigerator overnight. But this is not always convenient due to the constant attention to crafts.
Step 2
When making large pieces of crafts, plasticine can be made less plastic by mixing it with materials that are insensitive to heat. For example, it can be small pieces of copper wire or in plastic insulation. Cut the wire with scissors and mix thoroughly with plasticine. Or, for the future product, use wire as a frame.
Step 3
Small parts of crafts, such as grass, hair, leaves of molded trees, require different methods of strengthening. For example, spray hairspray or clear nail polish on the surface.
Step 4
You can resort to a modification method by tweaking the chemistry of the clay before you start sculpting. To do this, spread the clay evenly in thin pieces in a saucer of water. Heat in a microwave to make it run like oil paint.
Step 5
Remove the saucer from the microwave. Stir the resulting melt with water, and then mash this mixture, squeezing out excess water. Put the mass in the frost or in the freezer, and pour out the water and fill in a new one. So repeat several times, in fact, thereby achieving gradual washing out of the oily plasticizers. As a result, the plasticine will become much harder.
