UPDATE: Test results posted, lignin removal 6 6

 Well, let's hope that a year from now something like this doesn't suddenly happen to a book so treated.....

Lol, that is exactly what is going to happen to all books (or any paper items rich in lignin) over time without improvements in conservation science.

10 years of comic book and other paper artifact test subjects are still part of the research.  Some raw and unprotected, some in various types of storage: Mylar, poly, slabbed, vacuum sealed.  So far none have exploded😄

A decade after your whitening treatment, I wonder about the suppleness and flexibility of the paper, as well as how well it retains the whitening.  It's certainly a visually impressive and appealing effect.

Legitimate questions and of course the main reason for the varied types of storage and testing.  The whitening is a nice benefit but the main focus is longevity of paper and stability.  
 

I’ve done my own personal testing on artificial aging, lignin content, etc.  Of course those results don’t hold much water in the public domain hence all the third party testing underway.  The oldest test piece shows the same suppleness and fold resistance as when it was first treated, as third party results come in I will be happy to show them here regardless of success or failure
