MELT & POUR SOAP
1. There are two ways to melt the soap base:
a. In a microwave oven
b. With a double boiler or jacketed hot water bath ideally with thermostatic
control (like the
soup small heating kettles in restaurants.)
2. If you are using a microwave:
a. Thinly slice or grate the soap base for ease of melting.
b. Place the soap in a Pyrex cup and place it in the microwave for 30
seconds (for half a pound).
c. Remove and stir slightly.
d. Continue to microwave for another 30 seconds.
e. Add soap colorant and stir until blended (soap colorant should be
f. Add soap fragrance to the desired level, and stir gently and thoroughly.
g. Pour soap into soap molds. Let cool and harden before popping out
of the molds.
h. For fast set allows the soap to cool for 10 minutes, then cover in
plastic wrap and place in the refrigerator (not the freezer) until set.
i .Wipe and clean the microwave.
If you are using a double boiler or hot water jacket you will not need
a cup, and it will take longer.
TIPS & HINTS
1. Never allow the soap to boil. Boiling can affect the color, causing
a yellowish hue.
2. Children should not handle hot, melted soap without adult supervision.
3. Soap should be at 130°-140° Fahrenheit (55°-60° Celsius)
when it is poured. At this temperature it will be hot to the touch,
but not enough to burn.
4. Try not to over-stir when mixing in colors and fragrances. Should
you do so, allow the soap to sit for 10 minutes so that the air bubbles
formed can travel to the surface and be released. Air bubbles trapped
in the finished soap will spoil the transparency
5. Always pour on a level surface.
6. When placing an insert or an object in the soap, pour a first layer
and let cool. Add the insert or object. When you are ready to pour the
second layer, bring the soap to a slightly higher temperature (155°
F, 68° C). This will help keep the layers from separating.
7. Avoid diluting the soap with water or any other chemical. The only
exception to this is to add a maximum of 5% glycerine should you need
a softer or more transparent soap.
8. Avoid contact of soap with eyes.
