However, addition of high magnesian calcite and magnesium carbonate returned pH to values approaching or higher than initial values.
Hydraulic limestones, sometimes referred to as argillaceous limestones have a high proportion of clay and silicia (15-20 %) and can be either high calcium or magnesian.
Dolomitic and magnesian limestones, in addition to the CaCO3, contain a relatively large proportion of MgCO3.
MgCO3 are referred to as "dolomite" or as dolomitic limestone, and those containing between 5 -20 % MgCO3, as magnesian limestone.
The wet slaking method described below (handslaking) is a suitable simple means of slaking magnesian limestone quicklimes.

Overburnt magnesian limestone or dolomite hydrates very slowly and is just about impossible to hydrate when impure.
