Preparation of Porous Ceramic and its Utilization as Spa Compress Ball

Herbal compress ball has been traditionally used in Thai spa industry. The major limitations of the product are microbial contamination and a short reuse-cycle. Thus, this work attempts to develop the ceramics in the form of compress ball. The porosity of the prepared porcelain ceramics, which affects the different absorption and vaporization of essential oils, was studied by the variation of Al2O3 quantities and firing temperatures. The absorption and vaporization on water and essential oils of the developed ceramics were studied at ambient temperature (24-27 °C), 50 °C and 100 °C. The ceramic product fried at 1150 °C possessed a higher absorption and evaporation than that fired at 1230 °C in all evaporated temperatures. Moreover, in term of the absorption property, water absorption raised as the Al2O3 content increased however; at 1150 °C of firing temperature, water absorption increased to maximum at 4% Al2O3 content but decreased at higher content. In addition, ceramic compress ball with the optimal properties (fired at 1150 °C, 4% Al2O3) was prepared and 60 mg of mixture of Plai oil, Lemongrass oil and Kaffir lime oil were added into the compress ball. The product was then tested by 10 volunteers and it showed that 80% of volunteers were highly satisfied with the product. Even though, the ceramic compress ball product tends to have volunteer’s positive satisfaction, there are some issues for further improvement such as rough and hard feeling, shape and usability of the product.
