VEGETABLE GLUE
Of recent years efforts have been made to find a substitute for animal glue. The effort has met with success to a certain extent for particular kinds of work. Probably the newest addition to the list of vegetable glues is the mineral glue-silicate of soda. Liquid silicates were first sold for the manufacture of soap. In recent years certain forms have been used for light adhesive paper work. It is used in places where glue is too slow setting.
