Permanence/Durability of the Book-VI. Spot Testing for Unstable Modern Book and Record Papers.
Barrow (W.J.) Research Lab., Richmond, VA.
There is ample evidence today that acidity resulting from manufacturing processes is the principal cause of paper deterioration. The significance of this discovery is that purchasers can avoid paper manufactured in such a way as to be auto-destructive. This investigation explores the collective use of color spot tests to distinguish stable from unstable book and record papers currently being manufactured in the United States. The value of this type of testing is derived from its ability to separate quickly good from poor quality paper from the standpoint of useful longevity. These test results are qualitative, not quantitative, in nature. Thus, for example, while the acidity spot test will indicate the presence of acidity, it will not determine the exact amount. The spot tests for groundwood, acidity, alum and rosin can be applied to papers quickly by anyone without special equipment or training, with due caution in regard to handling the chemicals and interpreting the results. These tests only require small areas of a paper sheet, thus eliminating damage to large quantities of paper. A summary of instructions for using these tests is given. (Author/RM)
