Subject: Spot testing
I am searching for a replacement set of paper testers. We have a set of surface testers called the "Tri-Test kit, which was put together in part by the W. J. Barrow Research Lab. The booklet that comes with the kit dates from 1969 (a bit on the dated side). In the set there are 4 bottles with glass rods attached to the lids. There are solutions to test for Groundwood, Alum, Acidity, and Rosen. All you do is spread some of the liquid on your paper or board and watch for a color change. I'm looking for a similar set or suggestions for this type of quick test. If anyone has heard of source for this stuff it would be much appreciated. Ironically enough the booklet that comes with the kit is brittle.
