Pollutant Test
Before
Testing:
On the left in this photo are new MicroChamber file folders. On the
right are high quality, alkaline-buffered file folders. Each has one
half of a 34 year old, acidic, naturally aged book page. The page
portions were enclosed in the folders and exposed together to a pollutant
gas (NO2)
After
Testing:
The
page housed in the MicroChamber folder is shown folded, indicating
its retained strength. The page housed in the alkaline buffered folder,
shown here in small flakes, was so brittle after the test that it
snapped when folding was attempted.
