[Histonet] embedding beads/tissue marking dyes

We may be encountering some issues with our tissue marking dyes 'clogging' up our processors.  I"ve heard of a system where a coloured 'bead' is embedded right beside the tissue, and subsequently cut onto the slide.  This does not mark the margins obviously, but is used as a method to track like specimens that are grossed, embedded and subsequently cut in a row. (red, orange, green, blue.....)

I explored the archives for "embedding beads", but only found reference to a glass bead that is placed in the wax inside the block, but not subsequently cut.

PS: we are still troubleshooting our dyes (dilutions, brand, etc.), but if anyone has a brand of dye that they like and have no issues with, I'd be thrilled to get the information as well!

Thanks in advance,
