Lather & Lye

Troubleshooting & Safety

The part that turns worry into know-how: lye safety done properly (gear, ventilation, lye-into-water, cleanup), plus why a batch seized, separated, overheated, cracked, got soda ash or DOS, or never hardened, how to tell if a bar is safe to use, and how to rescue, rebatch, or safely retire a soap that didn't go to plan.
