Magnesium Carbonate
Magnesium Carbonate is more complicated than it first seems. There are hydrated carbonates, basic carbonate and hydrated basic carbonates, which are all commonly known as ‘Magnesium Carbonate’. Inoxia currently stocks two grades, which are light hydrated basic magnesium carbonate and standard. The light form is 2–2.5 times more bulky than the standard.

Light Magnesium Carbonate
The light, or low density form has the formula 4MgCO3·Mg(OH)2·4H2O and is also known by the mineral name Hydromagnesite. The low density is owing to the porous crystal structure.
It is the best version to use as climbing, gym or weightlifting chalk.
