Has anyone done any measurement of the differences in thickness of different manufacturers' foundation?
I began thinking about this when I was installing some crimp-wired foundation in medium supers this spring. It seemed thin and brittle. It was light colored, and I remember wondering whether it had been bleached, and if that had affected it in some way. The other thing I thought about was that it seemed as though it might have been adulterated with paraffin. I'm pretty sure that that wouldn't be the case...
This weekend I got a package of crimp-wired deep foundation from my brother, who had found it at his home. We had kept bees there in the mid-late 1970s. This foundation, from Dadant, was much more substantial and much yellower.
When it came time to electrically embed cross-wires, the thinner (new) foundation was much less forgiving than the thicker (old) foundation. It was easy to melt out a thin seam and leave a naked cross-wire in the frames with the thinner foundation.
I am wondering whether there have been any evaluations of different manufacturer's foundation. It is conceivable that 10 sheets from one manufacturer could contain a lot more wax than 10 sheets from a different manufacturer, just as a function of how thinly the foundation was pressed. There are obviously situations where you'd want a thin comb (cut comb honey), but for deep and extracting supers, I'd be willing to spend a bit more to get more. I might have shopped price this past time, but I am not certain I would do that again, given my experience with embedding wires this weekend!
Should we as the purchasers know what we're getting (how many sheets per pound, or what the thickness of the foundation is in fractions of an inch or metric)? Will the vendors provide us with that information so that we can consider it as we contemplate a several hundred dollar purchase?
