Dear Karen Sullivan,=20
If the bag is labelled Calcium Magnesium carbonate and you ordered =
Magnesium carbonate return it to your supplier. This is derived from =
Dolomite and the assay is variable. It is a natural double carbonate.
Magnesium Carbonate, Magnesite, is one of the ores of Magnesium, a =
crushed rock.
I am wondering if you actually need Magnesia, Magnesium oxide which is a =
fine smoke like powder, made by burning metallic magnesium in air. This =
is used as a Laxative.
Best regards,
Ivor Lewis.
