I've rarely had any honey to crystalize. If it has, it has done so at the top, usually just around the edges.
But, last December as I was checking a hive to be sure they had enough food, I found the hive almost completely empty. Empty of bees that is. But with LOTS of honey. There were no pests. No wax moths in the hive. No SHB. Might have been 50 bees.
Anyway....I took the honey out, extracted it and put it in jars.
I still have most of it and when I picked up a jar of it just now, I found there is about 1/2" of something solid at the bottom of the jar. Looks like wax. At least it is the color of wax. Very light tan in color.
What is it?
