Few substances are more generally
useful tllin glue. At one tine or an
other nearly every householder has to
use It, yet few persons know anything
about the different kinds or which Is
best for the purpose In hand.
For ordinary repairs to articles OF
wood, especially II no severe strain is
TO be placed upon the object, the pre-
pared CLUES are convenient and ade
quate They are therefore often chosen
In preference 10 the old fashioned sort
But for strength and durability no glue
which Is applied cold can compare with
the kind that Is first melted In a glue
pot and then applied hot, and of this
kind there are many grades, which
vary greatly In quality.
The manufacture Of hard glue, as 1t
Is usually called-that Is, glue which Is
TO be used hot-ls 10 a large degree the
utilization of waste products. The raw
materials are pieces sand serapings from
hides, chips and dust from horn work
Ing factories, parlngs from hoofs and.
best OF all, sinews from animals killed
for food IN the great slaughter houses.
The frst process Is soaking In lime
water. made thick enough to be called
"mIlk OF lime" In this bath the slnews
and other glue material remain for two
weeks or more, In order that all the
grease and blood may be eaten away.
but Immediately on removal the ma
terIal Is exposed 20 currents OF air.
which allow any adherng lime TO alb
sorb carbonlc acid. This checks the 0c-
tion OF the alkall on the animal matter
and makes Il possible TO keep the ma
terial In the dry state for an indefinite
