[Histonet] Stain and component shelf life

[Anatoli Gleiberman]

I am still using some stains from late 1800 to yearly 1900 (azocarmine, pyronin, indigocarmine) from IG Furberindustrie - and they are better than contemporary from Sigma.

The best staining I ever got from Metanil Yellow was from a bottle of powder over 20 years old!

Can you share this info with me too? We just got grief about this from our JC inspector about a month ago.

Can someone direct me to a reliable source for information on shelf life
of stains and components, specifically expiration date for unopened vs.
opened powdered/dry/granular stains?  I have "heard" unopened dry stains
w/shelf life of 10 years; opened dry stains w/shelf life of 5 years. Any
citation for that?
