I have this 20 gal barrel of old dark tulip popular honey that must be 25 years old. The barrel was coated with some kind of paint/teflon coating and has likely been crystalized for a long long time. When it was put up is was strong tasting and I didn't have a market for it so I just forgot about it. I plan to heat it up in a bigger barrel full of water and place a couple of bricks in the bottom of the water barrel and heat it up and liquify the stuff. Plan to re-filter the stuff for the paint chips (lead?) if any look like they came off the sides) and see if it would be fit to feed back to my current bees. I know where this honey came from and don't expect any foulbrood issues but maybe dysentery if feed too much at a time in cold weather . Worth the trouble or any other use?
