My old foreman in Toledo told me to always pre-heat the flask to 200 degrees before pouring, and after a bad cold shut on a big gear job, I finally listened.

Has anyone else found a specific temperature that works best for your particular sand mix?

Totally agree, that's way too hot for our shop. We just warm ours by the furnace overnight and it pours like a dream.

Our humidity here makes even warm sand tricky.

Your old foreman's 200-degree rule sounds like overkill for the sand we use.
