These comments may explain why I ended up with a puddle of shellac underneath a two-year old can of Zinser dewaxed sealer shellac this past summer.... top was tightly sealed, can was 4/5 empty but somehow had leaked out through the lid (to judge from the drip down the side of the can). No discoloration of the shellac, though, and no deterioration of the can itself. Never had that happen before, and I've been using shellac (mix my own and Zinser) for 15 years as a sealer for pine and other softwoods.

Thanks for the insights.
