Bead Options?

[Wharf Rat]

I have the older beads in one cooler door and the clay in the other. They both work.

I agree that the explanation of “setting” the clay beads doesn’t make sense to me.

The Boveda packs work with saturated salt solutions. That’s a well established method of calibrating instruments. I’ve found you can recharge them by putting them in a very moist environment and waiting.
