Re: [BKARTS] "Archival" tissue paper



"Numerous tests by HP concluded that the most commonly available 'pH test
pens' yielded conflicting results depending on the brand of the test pen.
These tests also gave misleading information such as the indication that
some coated papers contained acid when in fact they did not. If
archivability standards were better defined and applied, consumers would
only need to refer to the manufacturer's specifications and not rely on
third party suppliers."

In the past year or so I saw an article comparing various brands of pH test
pens, but now I can't remember where it was.
