How funny! You are so right!!!!!

What about the ink on all of those old reports and reference books? Isn't ink a 
dye in solvent?

The best special stains I ever did were back in the day when I made my own 

from dry chemicals that were already 20 to 30 years old.

Paperwork, just a way to decrease productivity!

Subject: [Histonet] Outdating- Embedding Wax and Mounting Media

  To all Quality Control Purists
There seems to be a growing concern with regards to outdating on reagents and 
their  continued use beyond this date.  I notice that Histological wax and 
Mounting media are dated with an expiry date. Just begging the question-should 
we go back. melt down and re-embed all old blocks in fresh wax ?? Should we 
recover slip old slides in fresh dated Mounting media. With all the fuss over 
quality control in the Laboratory and Government Lab Inspection oversight , how 
can this be ignored and our archives put at such dreadful risk ??
