We cast at 1400°(ramp 9999 on the controller) full blast straight in the furnace after the flask sets 5 hrs in Opti Cast....ramp down 650°per hour then cast at 850°.
How in the heck do I turn this image? URGGGH!!!!

As clear as you make this I have a question.
Your burnout is
Step 1 Ramp full to 1400F Hold for no minutes at 1400F
Step 2 Ramp down 650F per hour to 850F Hold for no minutes at 850F
Step 3 Cast
That's it?
How long does that burnout take?

we casted 2 model with and two models without. it was not a big difference, but under the microscope we saw better surface quality on the models with supports on.
