Re: Heating pad to re-liquify honey
1 jar? Large pan of hot water out of the tap. Let soak for an hour or two. Invert jar periodically to mix. Replace water if it gets too cool. Supposed to work. I just used the defrost setting on the microwave oven the one time I had to reliquify a jar of store bought honey years before I started keeping bees. Now I would place it in my incubator to warm up.
Maybe you could put the heating pad in a small ice chest and not worry about trying to wrap the bottles?
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
