As said before quartz and silica sand are bad news.  They cause silicosis. (Lung desease)

Try finding something commonly called "Black Beauty".  It is basically crushed furnace slag 
that comes out of large coal fired boilers.  Find a big power plant fired with coal and you will find
the slag.  It is very cheap in Ohio.  About $3.00/100lb bag.  Commonly used to blast bridge steel.

This material is very low in free silicon which causes silicosis.

Good Luck,

Dave
