Cast Iron Quality in my Foundry (From Brake Rotors)

It could be that you are melting vented rotors and they had alot of oxides formed in the vents "rust". But its more probable that the furnace environment is causing it "oxidizing".
Its pretty common with the hobbyist iron caster, and can be very difficult to manage. What type of furnace set up do you have and what is the fuel source? How large of a melt are you performing?
