The paste thus obtained has all the properties of gum arabic solution and dries to a lustrous mass.
Liquid sugar and lime paste. Allow 3 parts of glue to swell in 10 to 15 parts of the foregoing paste. Heat the mixture to the boiling-point. The paste thus obtained does not congeal on cooling and possesses considerable adhesive power.

II. Dissolve, with the assistance of heat, 50 parts of dextrine in 50 of water, stir solutions 1 and 2 together, strain through a cloth into a flat prismatic mould, and allow it to congeal. For use, melt a piece of corresponding size, and dilute the liquid, if necessary, with water.
Albumen paste. This is a misnomer, as it contains no albumen. It is partly decayed gluten from flour, washed with water and then heated to 60° or 68° F., when it ferments and becomes partly fluid. It is then dried at 77° to 86° F., and is claimed to keep any length of time in a dry place. Dissolved in twice its weight of water it can be used as a paste for all purposes.
Glycerine paste. Dissolve 2 ozs. of gum arabic and 4 drachms of glycerine in 6 ozs. of boiling water. This is a good paste for office use.
