Re: Re Block storage

From:Nancy E Weber

Hi Ian,
At the diagnostic lab I used to work at we would seal our blocks with
paraffin before we would file them.  At the embedding center, poured x-cess
paraffin on the hot plate and swiped face of block to seal it.  We had
blocks from the eighties filed that we had no problem recutting if we had to
that were sealed like this.  The only problem......just keep them in a cool
