Re: Sharp Sand Sources (?)
Sharp sand is mined principally for construction (masonry) purposes.
Because shipping is such a large proportion of the cost your best bet
would be to get the sand from a construction supplyer (any horticultural
supplyer probably got theirs' there too).
If you have any questions about the material you should be able to send a
sample to your state department of agriculture for a waste analysis ($4 in
NC) That would check for heavy metals, pH, etc. Generally testing for
agricultural chemicals is prohibitivly expensive; you have to know what
you are testing for. I don't imagine that anyone would have any need to
protect sand from insects or diseases.... but you never know.
