<Prior Art> Conventionally known clays used for arts and crafts, school teaching materials and the like are commonly known paper clays, oil clays and the like. These well-known clay for arts and crafts or clay for teaching materials are mainly made of granular materials or disaggregated plant bodies, and additives such as a binder, a fragrance or a pigment for binding the granular materials are added to this main material. , Many of which are made by adding compatible liquid materials such as water and oil.

As a conventional example technique for reducing the weight of the above-mentioned clay for arts and crafts and school teaching materials, there is one using shirasu balloon as a granular material. However, with this technology using Shirasu balloons as the main material, the main material itself contains a large amount of heavy inorganic substances (calcium carbonate, talc, clay, etc.) and the main material particles are easily crushed during the manufacturing process, making it lightweight. However, there is a problem that the incineration is not achieved sufficiently, and the incineration is impossible because the inorganic components are contained in a large amount.

<Problems to be Solved by the Invention> In the technique according to Japanese Patent Publication No. 51-893, it is premised that styrofoam is made into powder. As shown in Fig. 2, the powdered styrofoam causes numerous spinous depressions on the surface of the particles due to its physical structure properties, and the liquid material such as the mating liquid material is sucked and penetrates into the spinous depressions. By this, it becomes rich in water content or liquid content.

このため配合する水等の馴合液材が多量に必要となり、
その結果製品である粘土全体の重量は、あまり軽減され
ないという軽量化上の課題が残存する。
For this reason, a large amount of compatible liquid materials such as water to be mixed is required,
As a result, the problem of weight reduction remains that the weight of the entire product clay is not significantly reduced.

Further, in the case where the styrofoam powder particles have a shape close to a perfect sphere, there is a manufacturing limit to the miniaturization of the sphere diameter, and it is extremely difficult to manufacture a sphere having a diameter smaller than 1 mm. For this reason, there is a problem that smoothness and fineness of texture during use of the product are not realized, and the degree of conformity with the binder is poor, so that plasticity is poor and brittle.

品として鮮明な色付けが困難であるという課題もある。
Regarding the color of the clay according to the above-mentioned conventional example, since the styrofoam powder is grayish, the clay also becomes gray, and there is also a problem that it is difficult to make a clear coloring as a product.
