<Question 1: difference between archival and non-archival?
An Archival Adhesive, glue or paste needs to fulfil two main criteria:
1. To be reversible, i.e. to be able to de-laminate (normally in the presence of
water or heat) without leaving any trace of the adhesive, glue or paste
originally used on the cleansed material.
2. To be of a chemical make-up, that will not damage with time the material
being stuck . This normally means that there would be an inherent natural pH
value of 7.0 or higher.
Most starch based pastes and animal glues will meet the above criteria. There
are also several specially made Archival PVAs (poly-vinyl acetate) on the
market, which also perform well to the above rules.
