Glue to resist heat and moisture is made as follows: Mix a handful
of quick-lime in four ounces of linseed oil, boil to a good thickness,
then spread it on tin plates in the shade, and it will become very
hard, but may be easily dissolved over the fire as glue.
A glue which will resist the action of water is made by boiling one
pound of common glue in two quarts of skimmed milk.
