    Edgar Munoz Bad contamination there buddy!! Many things can go wrong. Simple things from lotion on hands, reused metal,not De-gassing at right temp,bad water, sand in sand blaster you are using presently. More then likely a good carbon block in your furnace to Purge. Dont reuse metal if you can help it. Is this happening on your first fire?

    Pete Ruberto I agree Edgar. Lots of things can cause it. I had a tech hold the framework with hemostats inside the blaster. As she was removing some oxide, she was blasting the metal from the hemostats into the frame. After we stopped using the hemostats, the problem went away.
