Dolomite supplies CaO and MgO.
Dolomite is calcium magnesium carbonate, theoretical formula
CaMg(CO3)2. Pure dolomite, with exactly equal numbers of calcium
and magnesium atoms, is formed by precipitation out of waters in
which both are dissolved. Most dolomite, however, is formed when
magnesium-rich waters seep through calcium carbonate rocks, and
the magnesium ions replace some of the calcium (up to half).
This process takes millions of years to complete, so some
dolomite may have only incomplete replacement, and thus be
higher in calcium than pure dolomite. Limestones in which
dolomitization has occurred are known as dolomitic limestones
or dolostones.
According to Obstler, dolomite may be substituted for whiting
in many glazes without significant changes.
