Test grid for casting

Have you ever wanted to know just what's happening in a flask when your casting? I have and still do all the time.
A long while ago there was a disagreement about flask temperature for a high nickel content 14k white gold.... I pulled out my trusty grid mold made some waxes.... 700 800 900 1000 degree f.... we ran them through the burn out....
It would seem by our results that the lower the flask temperature the better the grid filled. The best casting was at 700° F with a complete fill... I'll post the test pictures here when I figure out which machine they are on.
In the mean time if you would like some grid waxes to test with email me here you will have to share your results....
