Deacidification

Re: Peter Verheyen's query on deacidified paper, he (and others
interested) should read  Daniel, Flieder and LeClerc's article "The
effects of pollution on deacidified paper" Restaurator 11 (3): 179-207
(1990), which demonstrates that deacidified book papers, having once
been acidic, return to an acid condition fairly rapidly if stored in
sufficiently polluted environments, despite the presence of an alkaline
buffer.  Their research suggests, in fact, that the greater the %
buffer, the more pollution the deacidified paper can/will absorb.  Very
interesting and important research for all of us.
