Beekeepers: I've been making my frames from 3/8 inch plywood. Someone, somewhere once told me they thought plywood resin, even after being cured, could still give off vapors or volatiles or whatever they are termed. I don't quite buy it. Does anyone in the science community out there know anything about that? What are the chances that I'm contaminating my honey? Although the archives had some discussion on plywood hives, I didn't see any mention about using it for frames. Regards, Dick
