A little redundant on their part.

First of all the HT-2 test does not indicate at archival
levels. BUT no stain does mean very close to archival.

The test is done drop wise. The silver within combines
with any sulfur present in the emulsion. The stain is silver
sulfide. The drop stays in place 3 minutes then is blotted
off. The color must be read within a very few minutes
of turning the lights up. The sulfide is light sensitive.

Any further questions? Dan
