I did a lot of small castings, plaster molds with lost material,  in the
late'70s and early 80's.  clay,silver, lead, copper, and brass. I made a
gingery lathe '93? that required a lot of aluminum casting in green sand.
Have not worked with petrobond.  My proposal to artmilwaukee requires three
castings with a total weight of 30lbs.  pink foam positives.
