Waterproof or Glass Glue

This is the best glue to use for projects in which glass must be adhered to glass. For gluing decorations on glass jars, it is best to use the glue in its liquid state. For gluing marbles together or gluing metal ornaments to metal cans, use the glue in its gelled state. This glue is waterproof and can be used to mend china, to glue labels on home-canned foods and jellies, or to glue wood to wood.

2 envelopes (1/2 ounce) unflavored gelatine
2 tablespoons cold water
3 tablespoons skim milk
Several drops oil of cloves (optional)

In a small bowl, sprinkle gelatine over cold water. Set aside to soften.

Heat milk to boiling point and pour over softened gelatine. Stir until gelatine is dissolved. Add oil of cloves as preservative if glue is to be kept for more than a day. Makes about 1/3 cup.

How to use:
While the glue is still warm, brush a thin layer on the objects to be glued.

Store glue in a screw-capped jar. It will gel as it cools, but this will not affect its adhesive properties. Set jar in a pan of hot water to soften glue for reuse.
