Subject: Walnut shell grit blast media

Walnut shell grit blast media

From: Heather Galli <heather.galli>

We are conducting some experiments in the construction of leaded
bronze cast bowls employing the lost wax method.  We would like to
clean the surface of the cast bowls without getting rid of any
evidence imparted from the mold material. Upon investigation, we
have found that walnut shell grit might do the trick. Could someone
please recommend an appropriate grit size for walnut shell grit
blast media?   Also, a reputable source for purchase would be
greatly appreciated.
