1. Squeeze the round head of the duckling with yellow mud, then pinch two small black balls and flatten them to make eyes.

The duckling's mouth should be made of yellow clay. First, knead it into a cylindrical strip, put it on the duckling's face and portray it with tools.

3. In the end, we just need to pinch out the duckling's body, duck feathers on the top of his head and wings on both sides, and the lovely duckling is finished.

Brief introduction of plasticine

Plasticine, the predecessor of colored clay, has become children's favorite toy since 1956 came out. At first, plasticine was only gray, but in the following years, plasticine had various colors and smells. Including luminous, gold, silver, shampoo, shaving water and so on.

Gypsum action

Plasticine is a unique game. Plasticine is simple and convenient to make by hand. In production, the simultaneous operation of left and right hands can also adjust thinking and balance the intellectual development of left and right brains.

Gypsum type

Today, the material and technology of plasticine have changed a lot. Unlike before, it can't be mixed and reused, and it is rough and hard. The upgraded plasticine is called "colored clay" and the high-end plasticine is called "ultra-light clay". The most representative one is Okey clay.

Plasticine can be divided into industrial plasticine and ordinary plasticine for children to play with.

1. industrial plasticine

Mud like plasticine is used in industry and has a wide range of uses. Features: Advanced colored clay is nontoxic and environmentally friendly. Mainly used in handicrafts, hardware, plastic mold opening and student sculpture. Can be recycled and will not deteriorate for a long time.

2. Sludge-new plasticine

This plasticine is mainly made of calcium carbonate, liquid paraffin and glycerin. For infants, children and related personnel to practice making ceramic crafts.

Features: no preservative, liquid paraffin is oily, non-toxic and tasteless, and safe to use. It hardly evaporates and dries at room temperature, so it has good long-term stability. The processing is easy, and the bamboo knife can be used without hand contact at high temperature. Adding metal soap can not only improve the affinity between inorganic fillers and oil components, but also improve the viscosity of oil sludge. Adding liquid paraffin into oil components can improve the plasticity of oil sludge.
