Hi all,

I have been reading lots of stuff on the internet and have even made a few phone
calls to casting supply companies that cater to investment casting supplies for
industry.

What I am looking for is an affordable solution for an investment slurry and
reinforcement (white silica sand?) so that I can experiment with casting aluminum and
bronze at home. Some have suggested plaster of Paris, Portland cement, and
masonry mortar but I haven't found anyone who is willing to say what actually
works. I plan to cast wax patterns in rubber molds, invest them, do a high
temperature burn-out with a pottery kiln, and then cast while still hot.

Any of you folks have experience with this? Maybe shoot me in the right
direction for more info? Thanks.

Randy
