It all starts with the best raw ingredients – the Magnesium Carbonate. The misconception is that all Magnesium Carbonate are produced from mining and magnesite. Here at Tokyo Powder, we work closely with the Japanese salt industry who refine the Magnesium Carbonate as a by-product of the other salts from seawater. This also greatly reduces the environmental impact that is commonly caused by mining. It also helps to keep our chalk Calcium Carbonate free – which is a bad component for friction usually found in chalk that is derived from magnesite mining.
We don’t claim to have a uniform particle size of chalk, which we feel makes the chalk feel slippery. Instead, we start with particles of chalk between 3 to 5 micrometers – ideal for coating your hands for optimal friction. To stress again, we don’t grind down blocks of chalk to reach this stage, as it is refined from essentially liquids.
