Goal: make gentle, safe bars with repeatable steps and clear records. Safety & setup: clean bench, locked door, goggles, gloves, long sleeves, steady ventilation. Zone the bench into clean and hot/caustic areas. Plan & weigh: choose oil roles and percentages, set five percent superfat, run a trusted lye calculator, weigh oils in grams, and log every number. Lye solution: add lye to distilled water in small portions, stir until clear, cool to about one hundred degrees Fahrenheit, label, and park on a tray. Match temps & emulsify: melt hard oils, add liquids, strain, match oils and lye near one hundred degrees Fahrenheit, then pulse-blend to emulsion or light trace and stop. Color, scent, add-ins: run a one hundred gram test cup, disperse color first, weigh scent in grams at modest load, watch for acceleration or ricing, then set the full-batch plan. Mold & pour: line or prep the mold, pour in a steady stream, tap out bubbles, light alcohol mist on top, choose gel or no-gel and manage insulation, rest undisturbed. Unmold, cut, cure: release at about twenty four to forty eight hours when firm, cut even bars, rack with airflow, cure four weeks. Track one sample weight weekly until stable; pH strip after cure reads near nine to ten. Documentation & sales basics: photo key steps, record temps, grams, and times, label batches, and follow local cosmetic rules if you sell.
