Glass Negatives Organised

Glass negatives were removed from their original envelopes, in which they were not secured in any way, creating the risk of chemical interaction. Each glass plate was dusted off and washed on the non-emulsion side using a solution of water and rectified spirit with a small admixture of pure acetone. So cleaned, the negatives were put in paper sleeves and stored vertically in an archival storage box, where the original envelopes are also kept.
