Got a question for you, what is running after you turn the flame off? air compressor? Did you add a little ferrosilicone or is it ferrosilicate? to the iron or is that only when fired in a cupola? Thanks for posting the videos! tt

probably the blower, but what you hear may also be from the Thomas Air pump that I use which is a heck of lot quitter then an air compressor.

and yes I add Silicon to the melt just before pouring to help with graphite formation, sometimes it works sometimes it doesn't.

here's a short clip from today of me preheating the furnace in prep for melting CI





Will post the video of the pour this evening.
