I have 2 shaker boxes that my father gave me. One was stacked on top of the other, and now they're stuck together by the shellac. I assume it's because it's been so hot recently, because they've been like that for a while.
Any hints on how to gently get them apart? I haven't tried using that much force, since I'm afraid I'll damage them.
thanks much for any advice or hints! Sylvia
