Make your own bar

Make beautiful soap from scratch, safely and with confidence.

A calm, careful guide to making your own soap for people who have never worked with lye before. We cover the gentle on-ramp of melt-and-pour, then how cold-process soap really works, the lye safety that keeps you and your kitchen safe, how to read and trust a soap recipe and run it through a lye calculator, choosing oils for a bar that lathers and lasts, scenting and coloring naturally, and how to fix a batch that seized, separated, or never set, so you go from a wary first try to smooth, hard-cured bars you're proud to use and give.

Lye (NaOH) Calculator

Calculate the exact sodium hydroxide and water for any cold-process soap recipe, with a superfat you control.

Lye safety, every time: goggles and gloves on, work in a ventilated space, and keep kids and pets out of the room. Add lye to water, never water to lye. Don't use aluminum containers or utensils. If lye touches your skin, flush with plenty of running water right away (the vinegar-neutralizes-lye idea is a myth, skip it).
138.7 g lye (NaOH) and 319 g water for 1000 g total oils at 5% superfat.

SAP values vary slightly by supplier and harvest. Before you pour a real batch, cross-check this recipe in a second lye calculator (like SoapCalc) and weigh everything on a scale accurate to 1 g.
