We didn’t analyse the chemical nature of the particles present on the parchment. By visual examination the dirt looked very much as a combination of soot caused by the fire and particulate atmospheric dirt. The water used to extinguish the fire has probably caused the soot to become more compact and has allowed a firm adhesion of it on the surface. In some areas the soot penetrated deeper between the fibres of the parchment. We tried as much as possible to remove this dirt from the surface since this could be a perfect substrate for mould growth.

Did it result from the fire which caused the original damage to the book in the 18th century?
