How to make soap:
Gather your oils and weigh each type individually. Enter quantities into soap calculator http://www.soapcalc.net/calc/SoapCalcWP.asp
Superfatted to 10%
Add all oils to a pan ready for heating
Pour the suggested amount of water (from the calculator) into a large pyrex jug. If using coconut milk then reduce by ⅓ and add the same quantity of coconut milk once soap mix has emulsified.
Add the lye to the water and mix thoroughly with wooden or plastic spoon. Leave to cool for approx 10 minutes. Heat oil until any solid oils have melted.
Mix lye mix and oils when the are approx same temperature. Mix thoroughly using a hand mixer or stick blender. Add coconut milk as required.
Pour into molds and insulate with towels to ensure soap stays warm for as long as possible.
After approx 48 hours remove from molds and slice. Leave on racks to dry, turning if required, for several weeks to mature.
Caustic soda/Lye is horrid stuff prior to saponification. Wear rubber gloves, goggles and anything else you need to feel safe. Don't let kids or animals within a mile of you and your deadly chemicals. Other than that, its all easy peasy!
