[Scriptoris] Humidity and scrolls

As another Houstonian, I agree with everything Sara says, and want to add:
- If the W&N was particularly thick on the paper, that has on occasion created issues where the surface may have been dry, but not dry throughout, perhaps - overly thick paint can also sometimes lead to cracking as it dries.
- If you added something to the paints, such as gum arabic or ox gal, perhaps too much of that can cause a problem.
No specifically related to the paint problem, but high humidity can also cause the sticky seal part of the envelopes to glue themselves to the backs/fronts of the scrolls stored in said envelopes and it's impossible to unstick without tearing the scrolls, tho I guess you could try to use steam to unstick. So, I've started folding down the seal/closure part of the large envelopes, some cut the sticky part off altogether.
I also store my envelopes in a large, lidded, plastic underbed bin, and the one's that haven't made their way to the bin yet, aren't stuck. I also keep the house closed up with the A/C on.
To fix the one's still stuck together, you might try a hairdryer to put some heat on them to soften up the material that is causing the stickiness and slowly try to peal the scrolls apart.
Good luck, Hillary
