Description
[Process Materials Corp., NJ] A brand name for a marking pen containing a pH indicator dye. The Archivist's Pen contains Bromcresol green indicator solution. When a small dot of ink is applied to a dampened paper, it will produce a color that is an approximate indication of its acidity or alkalinity. A pH greater than 5.2 gives a blue color while a pH of about 4.5 is green and more acidic levels (pH less than 3.5) are yellow. The dye residue leaves a permanent stain on the paper and should not be used on a work of art. However, it may be useful for matboards, lining paper and hinges (King et al 1970).
