I am reprocessing some tissues that did not process adequately and was 
curious as to if after they are followed backwards through xylene, 100, 
95, 80 and 70, could the tissues go back into formalin with no adverse 
affects? Would it be better to simply leave them in 70% for the weekend. 
The one thing I don't want to do on a Friday afternoon is to sit around 
and stay late to process tissues.

Thanks for your help.
