    Hi Gang,

    Another point to consider is the quality of the sand, how sharp it
    is. Beach sand isn't very sharp. Most of the corners on each grain
    have been eroded by the constant wave action tumbling the sand. The
    best sand to get is that which has been mined. Because it hasn't had
    to put up with the tumbling caused by the waves, the grains have
    sharp edges & will work much better for sand blasting. Generally
    this type of sand is sold in 50 pound bags (in the US). It's used
    for sandblasting & as an ingredent in some grouts & mortars. You may
    be able to find it at some builders supplies,  brick yards or
    possibly cement companies could refer you to a source.
