Abstract:
A method of forming a far infrared radiation material on a surface of ceramic ware, comprising the steps of:a) forming a far infrared powder having granules with approximately 320 pores per square inch, drying the far infrared powder and subsequently firing the far infrared powder between 1280Â° C. and 1300Â° C. for 12 hours; b) forming a glaze including, by volume, approximately 50% melting agent, between 1% and 20% melting medium, between 1% and 20% of fire resisting agent and kaolin and between 10% and 30% silicic acid; c) forming a far infrared glaze mixture by mixing the far infrared powder with the glaze whereby the glaze mixture has, by volume, between 80% and 90% of glaze, and whereby the far infrared powder has a higher melting point than the glaze; d) adding water to the far infrared glaze mixture in a unit volume ratio of between 1:2 and 1:3 and grinding for approximately 72 hours; e) coating the ground far infrared glaze mixture onto a surface of an unfired ceramic body; and, f) sintering the coating of the far infrared glaze mixture causing the glaze to melt before the far infrared powder, whereby the infrared powder floats to an outermost surface of the melted glaze.
