I have been getting a lot of miscasts lately and don't know why?

Well I think I figured it out about the miscast. Thank you for all suggestions, what the problem was not enough oxygen in the gas mixture. Once the oxygen level was moved up the problem was solved. I guess the flame was not hot enough even though I had sharp edges on my buttons.

1). If u r burning out more than 1 ring at a time. Burn out this problem metal by it self you could have a cold spot in the burn out oven. Or have just overloaded the ovens ability . 2) if already burning out by its self increase the burn out temp...[More] by 100 degrees F. I have found this to help many...
