The bee keeper diaries

[Iowanian]

That's exactly what happened I think.

It's hard to tell for sure but I'd guess that really dark comb is more than 3 years old. The light colored stuff is new. Comb is al,
Most white when built and gets stained from pollen etc, but the darkness comes from a "shell" that is left by each larvae as it grows into a bee. The same cell isn't used multiple times, it builds up and gets dark.

I can tell you if you try to melt that old stuff for wax there is a lot of nasty crap to remove and it stinks
