Permanent Marking Pens

From:Richard Cartun

I know this has been discussed before, but I must inquire to see if
there have been any recent improvements.  We continue to see fading of
so called "permanent" ink used to label our glass slides, especially IHC
slides that have been heat-treated.  We are currently using
"Hist-O-Label" pens from Biesecker Biochemical.  Any recommendations? 
Thank you.
