I need to buy some bronze casting grain for lost wax casting. I have several parts, some of which have moderate details. The largest piece is roughly the size of a large deck of cards (but hollow). Most of the pieces will be machined after casting, and then assembled together, primarily using solder.
I will likely use Rio unless someone recommends a better source. I don’t care about appearance (i.e., color) and the price difference doesn’t matter for the quantities I need. I have my own (unused) crucibles. My priorities are:
(2) Low shrinkage
(3) Fine details
These are the choices, in my tentative priority order:
I think I’m leaning toward the Bronze Casting Grain, but I’d sure like to hear from someone who actually knows what they’re doing!
Any and all suggestions are appreciated. Thanks.
