Traditional hot melt glue

Application
Soak the glue overnight in about three to four times its volume of water. Heat this solution in a double pot until all the glue has melted. If the glue is too thick, add some more water to the solution. Do not allow to boil.

Precautions
The glue may be reheated two or three times. Old or dirty glue must be discarded and a fresh solution made.
