Glueing.
The right sort of glue to use for ordinary work is “best Scotch” (inferior kinds are often adulterated with lime). This glue is sold at all good tool shops; but if it cannot be obtained, choose the most transparent cakes. For fine work in light-coloured woods, Salisbury glue may be used; this is made in thin cakes, and is of a clear amber colour.
Preparation of the glue. Break it into small pieces with the hammer, and soak for at least twelve hours in sufficient water to keep it covered even when swollen by the water it absorbs: this water must be cold. It is no use attempting to melt glue by putting it into hot water; it will always be stringy, and give endless trouble. Put the pieces of soaked glue without any superfluous water into the glue pot, taking care that the outer vessel is kept full of water, which will prevent the glue in the inner vessel from burning ; this is very important.
