Various vinification techniques, some of which make use of a deacidifying
agent, are used for reducing acidity; for example, potassium bicarbonate is used for reducing tartaric acid by precipitating it in potassium bitartrate salt form.
We know how to retard and even arrest that degradation through such means as deacidifying
paper, providing ideal storage environments, and creating use surrogates to reduce handling originals.
The conservation of this material included reducing surface dirt, removing rust deposits from staples and dips, washing or deacidifying
the documents, mending tears, and humidifying and flattening documents.
But further costly processing, such as deacidifying
and removing the toxic byproduct furfural, was required before microorganisms could use the sugars.
Changes in the amount of activity related to pH testing and deacidifying paper are similar to 1995.
