Size to fasten Rubber to Wood or Metal.--Soak pulverized gum-shellac in ten times its weight of ammonia; in three or four days a shiny mass is obtained, which will become liquid without the use of hot water. This softens the rubber, and becomes, after the volatilization of the ammonia, hard and impermeable to gases and fluids whenever it is used on rubber connected to the wood or the metal of steam or other apparatus.
