The video of the above iron pour is located here:
I had rather a critical mass of junk in the driveway at the time, and such a clutter.
I have since cleaned things up, and I highly recommend not trying to cast metal in a cluttered area, and never pour molten metal in lace-up shoes like you see me wearing in this video.
I am lucky to still have toes ! Yikes, the dumb mistakes I made in the beginning.
I suspect that the iron I poured that day was at about 2500 F.
Iron-rated pyrometers are extremely expensive, and so I don't use one, and luckily you don't really need one with iron.
