C for 2 to 4 hours to produce a bamboo salt stone; breaking the bamboo salt stone and repeating the inserting and heating processes at 600 to 1000 deg. C 5 to 7 times; repeating the inserting and heating processes at 1000 to 1400 deg. C for 2 to 4 hours 2 to 4 times; and pulverizing the resulted calcium containing salt stone up into 50 to 150 mesh in a particle size.
