Re: [GSAS-Member] Dolomite and alkalinizing buffers
How about Hood Canal? Long Beach? (that said, only partially tongue in cheek)
Would they work?
Growing old is inevitable; growing up is optional.

Regarding dolomite or other alkalinizing buffers:
Apparently, dolomite varies in lead and other heavy metal content.
I did not learn if any dolomite sources are low enough in toxins
to warrant their use, but I did learn from one study
(http://ehp.niehs.nih.gov/docs/2000/108p309-313scelfo/abstract.html)
that 2/3 of ALL calcium supplements have higher lead levels than
allowable
by federal standards, they just don't require testing, so they are on
the
market.
I think oyster shells would be a better alternative to dolomite. Even
they
may be contaminated, depending where they come from. Another advantage
is that it is a more renewable resource.
The best alternative may be a powdered mineral supplement powder, or
refined
calcium carbonate powder and epsom salts, although that would lack the
important trace minerals.
Can anyone recommend a source of high quality oyster shells or
seashells?
