The same clean burning, odorless and smoke free gel used by food service professionals. Ignites immediately with the touch of a match and burns steadily and intensely until consumed. Safe, non-expolsive gel remains solid while burning so it can't spill if accidentally tipped over. Smart Can heat indicator tells you when it is hot. Heats up to 200 degrees. 7 oz burns 2 hours. Best size for use with the folding stove. Also fits fondue pots, chafing dishes, warming trays, etc.
