Here's a possibility - the color matches. Kashuba is the Tagalog (Philippine) word for saffron. Saffron is used as a histological stain.

Subject: Kashuba

While going through and recurrating boxes of vials, I found a vial of mystery fluid.  I would appreciate any insight about what this might be.  The vial is clear glass with a plastic pop-off top.  It has about half an ounce of liquid in the vial.  On the outside is handwritten "Kashuba".  The liquid inside is yellowish, slightly amber and appears to be kind of thick; not runny at all.  I'm guessing it might have been used for mounting slides.

I am not finding anything on the internet about a chemical with the name Kashuba.  I'm mostly concerned about this being a health and safety hazard.  If this is something that you know to be unsafe, please contact me directly; I read the ECN listserve in digest.

Thank you,
Andy
