Adding the Lye to the water
Lye (sodium hydroxide aka caustic soda) is always added to the water, NEVER the other way round (water to Lye) as there could be a VIOLENT REACTION. Personal protection equipment (goggles, gloves, long sleeve shirt, long pants (trousers), and closed toe shoes (no thongs or flip-flops)) must be worn as Lye is corrosive and will burn you. You don't want any splashing on you while you mix it in. The Lye must be thoroughly dissolved in the water before you add the solution to the oils.
