Original post:

>     I'm preparing a piano for our chapter's "Gross Anatomy" session, and would like to find a dye or universal colorant of some kind for CA glue and for nitrocellulose lacquer.  I want to make it easy to see how far CA penetrates the pinblock, and how far lacquer penetrates hammers.
