I have a bar of comb that is capped sugar syrup that I pulled from my topbar hive for a garden expo last month. Bees still have plenty of stores in the hive so I don't need to give it back to them, plus the weather has warmed and they are out collecting pollen and nectar. They are however out of drawn comb to lay brood in. This piece of comb was used for brood last year. I'd like to uncap it and be able to remove the syrup without melting the beeswax so I can put the empty comb back in the broodnest for the queen to fill it up with eggs.
Any suggestions on how to do that? Tepid water bath? 200 degree oven with it laying on it's side? Hot steam?
