Dear William ,
recent lectures by Charles Churukian here in Oz, indicated that the BSC is
currently going back and retesting samples of stains from years past, and
that initial findings suggest that if stored correctly the dye powders
appear to be largely unaltered even after thirty years in some instances. If
you want specifics, suggest you contact the BSC, or Charles direct; he's a
great guy and easily approachable.
Regards Mike Rentsch (Downunder)
