Howdy folks, I know this has cropped up before but what are the recipes for lining a cast iron portable forge. I know some think it is unneccessary but I'll be lighting this puppy up in cold shop usually and I don't want to crack the pan. Also I don't think I need to line the firepot either. The forge is an old buffalo forge cast iron deal with the side arm to hold the blower. Any advice appreciated. Cheers Ron Bakerian
