I just realized something that others may not do--our paraffin is
melted in a vacuum oven, which decreases the amount of bubbles in the
paraffin. Do you use one of these? This may be more valuable than I
realize, since I've never used paraffin without a vacuum oven.
To answer your other email, we leave our blocks at 4C anywhere from
overnight to a month later. Again, I've never noticed a difference
when sectioning cold paraffin blocks from room temperature blocks.
penguins, spoons, and you--what's life like among the flightless?
