Re: [RC] Calcium Carbonate - Jim & Drin BeckerYes isn't that what I said Ed ? Not more than 40% and not less than 38 % Calcium Carbonate , whoops , just went and checked the sack and it says not more than 40% and not less than 38% elemental calcium . So this is as pure as it gets than ?Drin (Obviously science was not my best subject :-) Are you sure that the label did not read 38-40% Calcium? Chemically pure Calcium carbonate is ~40.044% Calcium. I would expect ground rocks to contain a couple percent silica etc. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Ridecamp is a service of Endurance Net, http://www.endurance.net.
