I've never had the "white tea tree" honey crystallize. In fact, it should be on its way to you Berny. The black tea tree isn't flowering yet, and I've not had that issue with it either. I saw Nico's frames and maybe 5-10% is crystallized. We were going to put affected frames in the brood super but then found it was an issue with most frames. It certainly wasn't "gelled" honey. There is a lot of tea tree honey that is quite normal and sold at exorbitant prices in NZ. I was thinking the chinee apple might be more to blame, and even though it stopped flowering a couple of months ago, may have been left uncapped in some cells. There are thermostats that are made specifically for the ceramic reptile heaters we have, and our pet shop is going to order them, so we won't need any fancy electrical engineering, thank goodness (besides, Nico still hasn't been paid for piecing together the new lathe today although I offered him a banana). Anyway, back to the point...I am thinking the only thing to do will be to extract normally and warm the honey if it is too crystallized. I don't think it would be easy to liquify the honey without melting the wax if the whole super is warmed. Or take advantage of it and learn how to cream honey. I am thinking the thick stuff might not spin out fully anyway. Maybe then it can be cut out of the frames before "contaminating" any new batches.
