The possibility of using marble waste and fly ash taken from a textile industry as raw materials for producing fine ceramics was studied. Besides those two materials, clay was also used as the formed agent for ceramic body. There were four compositions noted as T1, T2, T3 and T4 that consist of marble waste 10 %, fly ash 10– 25 % and clay 65 – 80 %. They were formed by the method of slip casting.The tests pieces of these fine ceramic bodies were then fired at temperature of 600 °C. The glaze were applied to the bodies and further fired at temperature of 1150 °C in a gas kiln. Characterization results of those four composition tests show that the composition of T2 (70 % of clay, 10 % of marble waste and 20 % of fly ash) gives the best result.

Bentonite can be used as an additive in ceramics production. It can increase the thermal resistance and flexural strength of ceramics. Indonesia has a large amount of bentonite deposit. One of them is located in Karangnunggal, Tasikmalaya. The aim of this research is to study the effect of bentonite to increase the flexural strength of ceramic. The raw materials consisting of kaolin, feldspar, and quartz were used as raw materials in ceramics production. The weight percents of kaolin and quartz were fixed at 55 % and 20 %, whereas weight percents of feldspar and bentonite were varied at 25 %, 20 %, 15 %, 10 % and 0,5 %, 10 %, 15 %. The firing temperature was kept at 1,200 °C. Result of the experiment shows that the best composition to achieve the highest dry flexural strength at 254.70kg/cm2 is at 55 %kaolin, 20 % quartz, 15 % feldspar, and 10 % bentonite.
