The natural fragrant clay for kids was made by mixing saw-dust and shavings from species of Taiwan cypress, Japanese fir, and Camphor tree with edible raw materials. The proper formula was recommended, and the softness of clay could be easily adjusted by increasing the percentage of sawdust. The salt functions well in prohibiting the growth of bacteria and mold. Furthermore, in this study, the approach to prevent the occurrence of mold by controlling the moisture of clay showed better results than that of applying sodium propionate. A survey on characteristics of products was performed at two kindergartens and showed positive responses.
