another question for you jen, and back to your original question:
"I've been rearranging frames this spring, and have taken out about 6 or more frames that are what I think are too dark, and don't smell fresh. They have a slightly burnt odor. When I press of the comb it can be brittle.
What are some good signs that the comb needs replacement? And, can that comb be used for anything else?"
are these the frames you delivered a sulfur smoke to?
