I've done this both with and without melted paraffin.  I prefer having a dry holding tank.  Less mess.  Less waste of paraffin also.   As long as the holding tank keeps the cassettes from solidifying I think they can sit for quite awhile.  Or at least as long as it take to embed a tank full.

I want to get an idea of who is (and who is not, and why) adding paraffin
to the cassette holding chamber of the embedding center.  Once
processed-How long are tissues ok to sit without paraffin on them?

All thoughts, opinions, experience is appreciated...Thanks.
