Subject: Phytate treatment

Phytate treatment

From: Femke Segers <info<-at->

I am a paper conservator. My colleague and I are trying the phytate
treatment on maps with iron gall ink. For alkalisation, calcium
bicarbonate is used. However this is an elaborate preparation. Has
anyone used calcium hydroxide in this type of treatment? What is the
benefit of the bicarbonate?
