I need to make one additional point on my last post. I hit the send key too
quickly.
While I often remind people we are not in the food supplement business, just
as I believe water standards are useful reference points so do I think
vitamin pills and minimum daily requirements are another useful reference
point. In most any multivitamin you pick up you will find 2.0 -2.5
milligrams of a manganese compound--manganese sulfate in mine. You would
have to drink more than 2 gallons of vinegar that had been stored in jugs
glazed with Waxy Black to get as much manganese as you get in one vitamin
pill. If it were water or milk or coffee it would probably be close to a
hundred gallons. You'd have to be pretty thirsty to get much manganese that
way
As I said, this is a very stable glaze.
Regards,
John
