      Folks,
      Any concrete place has fine white quartz sand used for sandblasting and a variety of other things. Usually it's not graded using an AFS spec. But it's way better than sandbox sand. I can even get it in Fargo.

We have done several melts so far, with fairly good results with our equipment and tools, except that we have very poor results with our sand and mold making. We were hoping that someone with experience could observe one of our sessions, and tell us what we are doing wrong, and how to improve our sand and molds.
