 pounding sand
so...as to the different sand compositions...any expertise in this? silica, feldspar, "silver sand".... i bought what they called silica and that's what it says on the reciept...but the 60grit says "silver sand" and the 90 says feldspar.... as in all industries trying to make up losses from fuel prices, are they substituting cheaper goods for what is ordered? are these the same quality for refractory and casting as the silica i've seen in the recipes?  |

I looked up "silver sand" and it is any sand that is free of impurities such as "iron oxides that give sand the brown or yellowish colors". So I guess that it could be just regular sand that has been polished and washed or it could be ground from a quartz material. I have used regular play sand in making melting furnaces before with out any problems.
