Put on googles and gloves and make sure children and pets are safely away as lye is very corrosive and can burn skin.
Measure water and lye separately
Add lye to water slowly and stir continually
Measure oils and combine oils together
Wait for lye to cool to 120-130 degrees
Slowly add lye mixture to oils and use an immersion blender in short bursts or hand stir for about 45-60 minutes until trace (see video linked). When the mixture turns more of a white color, it's ready
Pour into molds and spray with rubbing alcohol (rubbing alcohol step is optional)
Let sit for one to two days then remove from molds and cut into bars
Soap can be used now but I prefer to let the bars sit for a few weeks to harden
