I once heard you could use plain Knox Geletin in a pinch, treating the powder
like hide glue crystals.  I guess it is really just refined hide glue-
certainly it is clear.  (Don't know which is worse....the thought that I'm
eating hide glue or that I'm gluing with jello)

Anyway, I've yet to try using the Knox stuff in the field, but your post
about the darker color of lesser quality glues coming through the ivory made
me remember the tip.  Has anyone out there tried this?   I may try it on some
non-piano related project first.
