Use this glue in its liquid state to attach glass to glass or wood to wood. It will bond metal to metal when it is gelled.
2 envelopes unflavored gelatin
1-1/2 tablespoons water
3 tablespoons skim milk
Let's make it
In the small mixing bowl, combine the gelatin and water. Add food coloring and extracts. In the pot, scald the skim milk. Pour the milk into the gelatin mixture. Pour into the storage container. The glue will gel in the container. To liquefy, place the container into a larger receptacle containing a bit of hot water.
