COMPOSITION USED FOR MANUFACTURING LIGHTWEIGHT POROUS POTTERY, METHOD FOR MANUFACTURING LLIGHTWEIGHT POROUS POTTERY USING THE SAME, AND LIGHTWEIGHT POROUS POTTERY MANUFACTURED THEREBY

摘要

The present invention relates to a ceramic composition for producing lightweight porous pottery, a method for producing lightweight porous pottery using the same, and lightweight porous pottery produced thereby. More specifically, the ceramic composition comprises pottery clay and a pore forming agent, wherein the pore forming agent is a mixture including expansible clay and silicon carbide (SiC). The pottery produced using the ceramic composition according to the present invention has the general advantages of existing pottery and also has a volumetric specific gravity of 2 or less which is significantly lower than that of existing pottery. Also, by controlling pore formation and having porosity, the pottery produced using the ceramic composition is appropriate for use not only as a storing container for various sorts of foods including fermented foods but also as a tableware. Thus, it is expected that the pottery produced using the ceramic composition can contribute much to an increased demand for traditional pottery.
