Ammonia
This is necessary for breaking down surfaces of highly glazed cloths so that labels will stick.
After labels or the backs of books have been lettered in white or black ink they should have a covering of shellac. A supply of the best white shellac may be obtained from the local paint dealer.
Occasional use is found for various other materials, such as powdered pumice stone, sponge rubber, India rubber erasers and art gum.
TOOLS
Folders
Several binder's bone folders, costing fifteen cents each, should be kept in the binding department.
Knives
A long knife, broad at the point, thin-bladed but dull, is needed for cutting paper after it is folded and for various other uses. A sharp, pointed knife is needed for removing books from the covers, or old labels from the back.
