HOT,SEUOID SOAP MAKING

Mr. W. Mcnzies gives in The Chemist and
Druggist the following practical recipe for
making soap without boiling: Take exactly
ten pounds of double refined 50 per cent
causic soda powder (GrecnDank), put it III any
can or jar with fOrty-five pounds QOur and
| half Galons) of water, stir it once or twice,
when it will dissolve Immediately and become
quite hot let it stand until the I've thus made Is
cold. Weigh ont aud place in any convenient
vessel tOI mixing exactly seventy-live pounds
of clean grease, tallOw, or oil mot mineral OLD.
| II grease or iaOw I've usei, melt 1t slow over
the fire until it is liquid and just warm-sdy,
temperature not over 1902 +. If oil be used,
no heating is required. Pour the lye slowly
into the melted grease or oil in small stream
continuously, at the same time stirring with q
| fiat wooden stlrreI about three inches broad
continue gently stirring until the I've and crease
are thoroughly combined and i'll appearance
| like honey. DO not stir too long or the mixture
will separate itself again. The time r,qlurcd
varies somewhat with the weather and the
kind of tallow grease, or OIL used from hitt .t
| to twenty minutes will be enough. Wien the
mixing is completed, pour OF the liquid soap
into any old square box fer IL mould sufficiently
large to hold it, previously dampGmn- the
sides with water so as to prevent me soap
sticking. Wrap up the box well with OLD
blankets, Or better still, put it in warm place
until the next day, when the box will contain Il
block of 100 pounds of soap, which can alter
ward be cut mp with wire. Remember the
chief points in the above directions which must
be exactly followed. The lye must lie allowed
to cool. If melted tallOw or grease I've used 1t
must not he more than warm. The exact
weights OF double refined % per cent powdered
cauStic soda and tallOw or oil must be taken
also the I've must he stirred into the grease, not
grease or oil added to the I've. If the grease or
tallOw used he not clean, OF contains salt, IL
must be "rcndcre1,' or purified, previous to
use, that is to say, boiled with water ana al
lowed to become hare, again TO throw out the
impurities, Any salt present Will spoil the
whole operation entirely, bat disco 0rcd or
rancid grease or tallCW Is Just as good az llcSll
for soap-mGkinS purposes.
II the soap tuIn ont strCaky and uneven IL
has not been thoroughly mixed. If very sharp
to the taste too much SCda has been taken. 1T
soft, mild, aud greasy. too little soda has been
used. In either case it must now be thrown
into par, and brought to boil Will a llttle
more water. Ia the first case boiling Is al tiat
necessary in the other instances u very little OIL
or q very little more of tho doub.c-Teined pow
dered caustic soda must be- added t. the water
These things will never happen, however. ii the
directions are exactly followed, and after tho
soap has been mad" several times with the cX-
pcriencc thus gained the process is extremely
easy and the result will De always Il good batch
of SOAP Beet talinw makrS the hardest soap
mutton tat Il rather softer soap; OF OILS. cotton
seed Is The cheapest and best, but th" soap Is
mnch softer, latherlng very freely indeed. Or
binary household tat or dripping will ma lie
nice soap, ANA in many places can br ohaned
at. triHing cost. and in exchange Tor
goods sold. Such grease, however, must be rare
fully examined for salt which it often contains.
1t will he evident that any smaller quantity OF
soap ear he made at Il time, according 10 the
above directions, by taking the ingredients III
exact piODnrt ION. II il not advisable to make
more than double the quantity prescribed, us 70
is iiflicult TO work more by hand.
