Excerpt from Paper Testing Methods: Microscopical, Chemical, and Physical Processes Described, With an Account of the Apparatus Employed
All changes and additions to the previous report are presented to the association for comment, and it must be understood that some of them - for example: the qualitative tests for glue and rosin, can be only tentative until their application in general use has shown conclusively that they are worthy of adoption as standard methods.
Under stains there has been added what is known as the Jenk's stain as a supplement to the Herz berger stain for papers containing small amounts of rag.
Under testing devices, there have been included photographs of the Thwing paper scale, the new Perkins quadrant paper scale and the Thwing tearing tester.
A note on the meaning of Substance Number is also included by way of explanation.
Methods for determining the machine direction of paper are included.
