I purchased a new Devil Forge all-in-one kit here: commercial link removed and after following the instructions to fire it up at low pressure (0.05) for 10-15 minutes with the lid open in order to cure the refractory inside I noticed that the bottom of the forge is now cracked:
I sent them an email asking which brand of refractory they used but its the weekend and I don't expect a reply before Monday. In the meantime, does anyone have any experience with devil forges and do you recommend any particular refractory to fill in this crack with, or do I even need to worry about this crack in the first place?
