Can a painting get moldy?

[Jennifer Bogartz]

Thank you Clayton! I'll take a Q-tip dipped in alcohol and test it out on a painting that I don't care much about. I was thinking that because I was stacking the paintings that maybe the non-shellacked side of the paintings were reacting with the painted side, but I don't know. Is there a better way to store oil paintings done on paper?

The old guys called it Glassine Paper. I would ask a conservator but I would think that an inert, acid-free, fairly slick paper would do as a barrier sheet. These sheets are commercially available to industry much cheaper than from art supply stores. A little Internet searching should turn up something. Good luck.

It's still called Glassine - you can buy it by the roll. I use it as my first protective layer when packing a painting for shipping.
