After reading so many messages, I just gotta tell 'ya:

S-I-L-I-C-O-

N-E... is used to make titties bigger.  S-I-L-I-C-O-N is the sand you
refer to, and what they make computer chips outta...

    I believe that the sand (that's used in the mold) gets into

surface

of the finished piece and causes both welding and machining problems.
