Today, gypsum is used both in the sphere ofEntertainment, and in construction and repair. Unlike plasticine, gypsum, while having the same softness, retains its shape when hardened, which makes it an ideal material for making casts or figurines.
But in order to make out of it some thing, you need to prepare it in a special way for modeling.
You will need
- Gypsum, clean water in a jar, a small basin, a wooden spatula or a tablespoon
Take the basin and half fill it with water. After this, gradually start to pour gypsum there. Sypat need small portions, waiting for the fact that at the time of the next filling of plaster, the previous one was already lying on the bottom. So rinse until a small island appears above the water.
Now pick up a wooden spatula orA tablespoon (which is more convenient or more accessible) and start to mix gypsum in water quickly, making sure that there are no lumps left (which it is convenient to crush with a spoon and immediately stir with the rest of the mass). Stir is necessary to the state of sour cream. If the mass at you has turned out excessively liquid, add in it some more gypsum, if on the contrary - too dense, add in it some water.
After preparation of this solution, gypsum can beuse. However, remember that in 20-30 minutes it will freeze, and before that lumps will start to form in it, so it's best to use gypsum solution immediately after mixing it.
