Abstract: The present invention relates to a synthetic clay composition which does not harden and thus can be repeatedly shaped without water while maintaining the shape for a long time and, particularly, to a novel synthetic clay composition and a method for preparing the same. The synthetic clay composition is soluble in water, and thus can be easily washed and is highly safe for the human body. Further, the synthetic clay composition is light and can be repeatedly newly shaped as desired. In addition, the synthetic clay composition has an excellent ability to maintain a shape, and thus can maintain the same shape in an agglomerated form for a long time, and can be used for play such as throwing.

Abstract: An air clay and a method of manufacturing the same are disclosed. In one embodiment, the method includes i) selecting at least one raw material from a group consisting of sand powder, shell powder, crop powder and a mixture thereof, ii) finely grinding the raw material to prepare a base material having a particle diameter of about 0.02 mm to about 0.2 mm, iii) adding about 10 wt. parts to about 30 wt. parts of glycerin to about 100 wt. parts of the base material, iv) mixing and kneading these materials together to form a paste and v) adding about 0.1 wt. parts to about 9 wt. parts of a liquid coagulating agent for water treatment to the paste and mixing these materials together. According to one embodiment, the clay is useful for various types of play and learning for infants and young children.
