The ones I'm messing with are the big 65% ones. I dried them out completely and there's a good amount of salt in there. So much so that if I filled it like a ready-to-pop balloon like yours, it should remain saturated.
Now I'm not sure, though. I think I'll fill them the rest of the way and mess around with it some more.

It does make sense, what you found out. If these things are made with just enough salt to saturate the design amount of water, that creates a stumbling point for recharging them. Get too crazy and it's going to give up copious amounts of vapor till it reaches saturation again and starts to work right.
If we didn't know what was going on, we'd likely try recharging once, assume it doesn't work, and not bother again. Easier to just buy some new ones.

Thanks for hanging with me on this, my brother. Ya know, this is just how we all invented the hcm and hcs beads. A whole bunch of guys back at the old place joined me and we messed with a bunch of media till we got it all dialed in with real-world data.
I still haven't figured out how to improve on hcm beads. I tried tons of salts, denatured alcohols, glycols, combinations of those, saturated polymers, everything I could think of.
It's still easier just to use hcm beads with Boveda packs for an extra water-sink and to keep them dialed in. It's an awesome combo.

No problem Scott.

Yeah, these little ones seem to have very tight margins for how much water they can hold. Neither of the two in the attached photo were recharged by dunking, they were both allowed to sit in sealed containers with moistened sponges at the opposite end of the container. The 69% pack is puffed up, but to no where near the amount that the one with the failed label was. The 72% pack has even less water in it than the 69% pack.

I have the failed label pack sitting out on the counter, once it drops back to something resembling original size, I'll test it again.
