BASIC MAGNESIUM CARBONATE & GYMNASTIC CHALK
BASIC MAGNESIUM CARBONATE has been produced since 1950 and widely loved among customers for its superior quality in purity and lightness. In 1983, we developed Block "GYMNASTIC CHALK" which is shaped by de-watering magnesium carbonate slurry. Hereafter, we successively expanded the product line to Gym Chalk Nuggets. This series of chalk products are mainly used for gymnastics, rock climbing and weightlifting, and mostly exported to North America and Europe. Some are exported to Latin America, Australia, Asia and Africa.
