Plasticine composition: What is he?
Plasticine has a special consistency that allows you to make any figurine from it. Rarely someone thinks that it is in its composition. And this is very important, because plasticine is located in close contact with the skin of the child.
Now there are a lot of his varieties. The composition of each species may vary depending on the destination. For example, there is a plasticine that resembles a foam, it is air and light. So the composition will be slightly different from the classical option.
But there is a classic formula for the manufacture of plasticine, "backbone", which is taken as the basis of which kind of plasticine is not selected. It includes:
- clay powder crushed to dust state;
- beeswax;
- fat animal origin;
- ceressine;
- dyes;
- petrolatum.
Separately, each element is safe for the health of the child, if using plasticine by purpose. This means that in general such a creative tool is not dangerous if it is not eating it.
It is important to pay attention to other elements in the composition that is not listed. They can be harmful. Also, excessive addition of dyes characterizes the mass not from the best side. But, the more Vaseline, the better. After all, it makes plasticine softer and more pliable.
Ceresin is a mixture of saturated hydrocarbons. The substance is very similar to wax, odorless. Thanks to him, is familiar to all clay-like consistency.
Unlike varieties of clay and its composition
A large selection of plasticine allows you to purchase such that the child will like. Before buying, it is necessary to get acquainted with its composition.

Recently, the dough for modeling - derivative of plasticine has become very popular. It is softer and air, the child does not need to be reinforced to give it a form. Such plasticine has an impressive amount of Vaseline and Glycerin. As a result, the mass becomes very soft, but fat. After modeling the hand, the child becomes fat. That is why it is better to have a napkin at hand. Plus such plasticine - it does not dry out for a long time, therefore it is considered more practical.
Ball plasticine is another popular material for waving. In its composition, foam balls and a special adhesive substance that glues them. Also present glycerin and frozen gel.
Thermoplastin has a similar composition with simple plasticine, but includes one important component, which allows you to have a high temperature of the product under influence. This component has the name "Polyvinyl chloride". This substance, as if gelatin, at high degrees absorbs all moisture. As a result, the figure becomes solid, as if frozen clay.
How to choose high-quality plasticine?
Usually choosing plasticine, parents are focused on the number of colors, the company and the cost of the goods. But the most important thing is to study the composition. If there are no such instructions on the package, it is better to leave such plasticine on the store shelf.
An explicit sign that this product does not correspond to quality is unpleasant or, on the contrary, too saturated "perfumed" smell. This fact indicates that low-quality raw materials have been used or too many flavors added to hide it.
If there is an opportunity before buying to cut off a piece of mass, then it will immediately allow you to decide on the choice. High-quality plasticine should be softened in hand, become plastic. Also should not be traces in the hands of the stains of the dye.
Modern plasticine is constantly improving. Recently, even "edible" options can be found in stores. If suddenly the child will eat it, there will be no consequences. It is absolutely safe and non-toxic.
