Hello Forum, Is there a standard temperature one's investment shells should be prior to pouring with aluminum? I have a handful of suspend-a-slurry shells I made. Their burn out went fine but I could not do the casting at the time, the burn out was done. So now I plan on reheating them in my electric burn out oven, prior to pouring. In the past I have used a temperature 1/2 of the metal I was pouring so roughly 700 F for aluminum. What are other people using. I am going to place the shells in large tin cans filled with sand to keep them still and not cool too fast. Jgaertner
