When fat and lye are brought
together under the right conditions, they react to make soap and
glycerin, and this process is called "Saponification."
It actually takes several weeks to complete the process of saponification
and the homemade soap needs to sit and age before it can be used.
Right after it is made there is still "free lye" present
and fresh soap is very caustic. Most traditional recipes for soapmaking
call for lye (which on the farm was made from hardwood ashes),
fat (saved and rendered after hog butchering) and water.
A milder, moisturizing soap can be made by substituting the water
with milk. . . goat milk of course. Following the recipes exactly
and careful handling of the ingredients is critical for successful
soap making. If the proportions are correct and saponification
is complete, the soap will be neutral, if any free lye is present
the soap will "bite."
Lye
Soapmaking can be a somewhat tricky and even dangerous project
because lye is a very caustic substance. Keep children and animals
away while making soap. Never add hot water or milk to the lye
crystals, they will heat up anyway and using hot liquid will cause
it to spatter. Wear rubber gloves while making soap and have
vinegar or lemon juice handy in case you get lye solution on your
skin. Also use safety glasses. Do not get lye solution in your
eyes or swallow it. Rinse utensils after being in lye solution.
It is very important that all utensils used to make soap are not
going to react with the lye. Use only glass, stainless steel,
wood or plastic. Never use aluminum or iron.
Fat
In this recipe lard can be used for the fat since it was the
traditional favorite, is readily available and gives one of the
best textures. Many people interested in purchasing handmade soaps
however will want them to be vegetarian, therefor, vegetable oils
such as olive oil can be used also, but will make a softer bar
of soap usually.
Molds
A mold can be made from a wooden box. Styrofoam works well also
and will hold the soap at an even temperature for 24 hours. It
should be about 30"x 3.5"x 2" deep for the following
recipe. Line the mold with a piece of dampened cotton cloth or
plastic (an opened garbage bag will work), trying to keep the
cloth as smooth as possible avoiding wrinkles that will be set
in the soap. Interesting shaped molds lined with petroleum jelly
will also do. Another damp cloth will be needed to cover the soap
after it is poured.
Equipment needed
Ingredients Needed
Pour 6 1/2 oz lye (half the can) slowly into 6 cups goat milk,
using a wooden spoon to stir. This solution will rise in temperature
to about 115 degrees F, turn gold, smoke and very nasty fumes
will rise. Avoid breathing these fumes Stir occasionally until
the solution temperature drops to 85 degrees F. and lye crystals
are dissolved.
Add 4 teaspoons borax and 2 cups oatmeal to the oil or fat, slowly,
to avoid lumps.
Slowly mix in (on low speed if using electric hand mixer) the
oil or fat (at 85 - 90 degrees F.) being careful not to splash.
Rapid addition of fat to lye solution can cause separation. So
can jerky, uneven stirring.
Continue to stir for 15 minutes, then stop and let mixture sit
for 5 minutes. Stir again for 5 minutes, then let sit again for
5 minutes. Repeat this again, but watch carefully because soap
will suddenly take shape. Take a spoonful of soap mix and holding
it about 2 inches above the bowl drip it back onto the mass. If
the ribbon stays separate and doesn't merge with the rest immediately
the soap is ready to pour.
Pour into mold and smooth top before covering with the damp cloth.
Keep the soap covered for 24 hours, then cut into bars and let
air cure for at least 3-4 weeks before using. The longer it sets
the better it gets usually. Bars will shrink considerably while
drying.
