Angelo Deacidification

I finished washing the folios on Thursday and started de-acidifying on Wednesday in the evening. Due to the lack of large felts for pressing, I’m only able to complete one section per day.

The method used is: 1lt of Magnesium Bicarbonate mixed with 100ml of 1% gelatine solution as a sizing agent. This is then brushed onto the recto of the humidified folios and left to slightly airdry before being pressed.

I am then doing paper repairs, section by section when they’re dry, instead of waiting for them all to be de-acidified and pressed. In this way, I can get a section done in a day.

Kozo 23gsm and Tengujo 11gsm are being used as repair papers. and the single sheets are being guarded together insitu to form a whole section. This is then pressed.
