hi mikey,
some very nice looking wax you harvested!
about the honey and slumgum..........this is what i would do, i would heat just enough so you can filter the slumgum from the leftover honey. dilute your honey with water (i would probably use distilled) and feed it back to the bees, 1:1........
throw the slumgum out, unless you want to try and salvage whatever propolis is in it.
do you know why you lost the hives in november/december?
