Tourmaline that belongs to the hexagonal system having electrical features is widely used as a multi-functional ore from high emission of far infra-red rays and II-Ray action to emission of anions, but, as it is very weak to heat, in case of ceramic balls formed at the firing temperature of ******0 degrees in centigrade, it is hard to expect the original functions, and, even in case of applying tourmaline with heat of less than **0 degrees by flit processing, there have been many difficulties in use due to continuing particulates.

However, through constant research and development, we have completed tourmaline balls by the temperature of less than **0 degrees in centigrade with a mixture of pure tourmaline powder (**5 Mesh) with functional ores, using a new processing method, and as the result we have made the functions maximized.
 
Various kinds of ceramic balls are available such as alkali ball, illite ball, dechlorinating ball, antifungal ball, silver nano antifungal ball, negative ion substitution ball, super ceramic ball, calcium alkali ball, and Pi-water ball.
