Not sure why you would totally dry beads and put them back in, not really how they work.. I don't think.
First of all as people have said, or should have, it's not great to spray your beads, everyone does it but it's still not the correct way to use them and it damages them. If you want to raise the RH of beads put them in a ziplock baggy with a small plate with a damp sponge, dampened in distilled water. Let them sit for a few hours, remove the sponge and put in a hydrometer and let that sit then check the RH of the beads, repeat until the beads are where you want them, spraying them causes cracks to form, why people end up with lots of little pieces of beads and bead dust.
To dry beads you can spread them out on a tray of some type and put them in the refrigerator, the cool dry air in the fridge will slowly bring the RH down, without exposing them to heat, it's a very fast process so you need to check on them after a half hour or so, then bag them up with a hydrometer and check them again.
Not trying to be a douche but this is how Scott says to raise and lower the humidity of the beads and they will stay perfect for many many hundreds of years (ok not hundreds but lots and lots).
It's just time consuming and many people don't have the patients to do it that way.
Good luck getting your box all set!
