[Histonet] paraffin sectioning troubleshooting

[William Ares]

As a newbie to paraffin sectioning on a paraffin microtome, I've been plagued with differential results since starting.  My current issue is that as they're cut, my sections are rolling back up on themselves instead of coming off the blade with the appearance of a venetian blind (as they were when the sections were looking good).  As they appear brittle, I've tried putting the blocks in a humid environment to try to rehydrate them a little, but to no avail.  Anyone have any good troubleshooting tips for me?  Thanks in advance.
