Soapmaking requires the mixing of caustic soda (sodium hydroxide - NaOH) in water to produce a lye solution.
Lye is a very strong alkali and can cause severe burns.

When mixed with water it releases heat causing the mixture to heat up very rapidly. Mix your lye water outside if possible. Stay away from fumes coming out of your container as this steam can burn as well. Use a plastic pitcher for mixing and label this “LYE DANGEROUS”! Do not use this container for anything else.

Dry lye is fairly benign. Once dissolved in water, it becomes very ‘caustic’. A single bead or flake of lye can cling to moist skin and result in a small burn.

It is very important to wear long pants, long sleeved shirt, rubber gloves and eye protection. ALWAYS add lye to the water, NOT the other way around! If you do, a volcano can erupt out of your container and burn you! Keep your lye dry in a sealed, properly labeled container. Keep securely away from children.

Lye can attract moisture and become hard. If it does, it has lost its potency. Dispose of properly. Spillage of dry lye are best swept up and disposed of. Mop the area thoroughly with lots of water. Rinse all brooms, mops or dustpans afterward. Do not use vinegar to rinse off lye on your skin. Lye and vinegar create more heat, which causes more severe burns. Lots of plain water is best.

Respect your lye and it will respect you. )
Happy soaping!
