Your First Batch of Soap, Step by Step

Your first batch of soap should be boring: a forgiving recipe, room-temperature ingredients, no fragrance, no color. That’s how you learn what trace looks like without fighting the batter. Plan about an hour, then four to six weeks of waiting. If soap making is completely new, read soap making 101 first, and keep the glossary open for unfamiliar terms.

What you’ll need

Everything is on our printable beginner checklist. The short version: goggles, gloves, a digital scale, a stick blender, a heat-safe pitcher, a mold, and the ingredients for a simple three-oil recipe like our beginner soap.

The process

Gear up. Goggles, gloves, long sleeves. Kids and pets out of the room.

Weigh everything first. Lye, water and oils into separate, labeled containers. Weigh in grams.

Make the lye solution. In a ventilated spot, sprinkle the lye into the water, never the reverse, and stir until clear. It gets hot fast and gives off fumes for a minute; don’t lean over it.

Blend to trace. When both are around 100°F (38°C), pour the lye solution into the oils. Stick blend in short bursts until the batter thickens and a drizzle leaves a faint trail. That’s trace.

Pour, cover, wait. Pour into the mold, cover it, and leave it alone for a day or two.

Cut and cure. Unmold, cut into bars, and let them cure on a rack for four to six weeks.

Cleaning up

Raw batter is still caustic. Wipe out bowls with paper towels, leave tools to sit for a day (the residue turns into soap), then wash them as normal.
