Don't you just love the way they used to store chemicals back in the day when men where men and women were women? We use a fair bit of Rose Bengal as a triplet sensitiser for the photochemical synthesis of 1,2-dioxines from dienes and oxygen. At the moment we are using some top-quality Rose Bengal from the world renowned chemical supplier Gurr:

A student once told me he was looking for Bengal Rose, which I assume is an Asian lady of somewhat dubious reputation :-)
yo, i have two of these acridine orange and malachite green.. i found it somewhere in very old stuffs- what is this things? looks like a paint from minerals? do i must add water and then paint with it?
I wouldn't use Acridine Orange as paint - it is used for staining DNA, and is a known MUTAGEN.
