Mining the Archives Project – Conservation Update

I’ve been busy working away on the mining the archives project and thought I would give a quick update on what’s been happening to that volume we found all the lead deposits in…

The 18th Century account book of Robert Thornhill (D307/B/19/1) has now been dismantled and cleaned. The cleaning process was very delicate as the edges of the pages are very fragile. Each page has been lightly surface cleaned using a ‘smoke sponge’ which is designed especially for conservation cleaning, and then brushed gently with a very soft Japanese brush.

The next step in preparing the pages for repairs is to wash them… yes really! It may seem like a strange thing to do, but we actually give each page a bath in a tray of water! This removes damaging dirt and impurities, and also re-invigorates the paper fibres giving it additional strength. The inks are tested for solubility first, as we don’t want to lose any of the information. The pages are given support whilst they are in the water using insect netting, and with a bit of care can be handled easily when wet.

After a good soak, the pages are removed from the bath and are left to air dry individually on pieces of thick blotting paper. Once dry they are ready for repairs to be carried out.
