Pour Plan: Soap Layers, Swirls
Lye & Colorant Calculator
Draw the soap bar you want to cut, and Pour Plan splits your batter into colored portions: the grams of batter for each pitcher, the colorant for each, and the order to pour.
Most soap apps stop at the lye number. Pour Plan starts from the bar's cross-section. Pick a style, drag the layer lines on the drawing, drop a colorant onto each portion, and the pour plan updates as you go.
LAYERS (FREE)
• Up to three layers with a gold mica line between them
• Drag a layer line and every portion's grams change with it
• Each step says what to do with that pitcher: pour at light trace, pour over a spatula, texture the top
COLORANTS
• A library of 19 pigments, oxides, clays, micas and plant colorants, each with a usage rate you can change and a note on how it behaves in lye
• Teaspoons per pound of oils, percent of oils, or grams per kilogram, scaled to the oils in each portion
• Plant colorants and micas are flagged: the drawing shows the planned look, and some colorants shift in lye
THE LYE CALCULATOR UNDERNEATH (FREE)
• NaOH, KOH or both, superfat, lye purity and three water settings, for cold process, hot process and liquid soap
• 23 oils with saponification (SAP) ranges and the published source for each
• A worst-case superfat check that tells you when a blend could run lye-heavy
• Fatty-acid profile and iodine value of your blend
• Weigh-out checklist in pouring order
PRO, ONE-TIME PURCHASE
• Swirls: in-the-pot and drop swirls with up to six portions, and a fourth layer
• Design book: save every design with its recipe and notes, and print a pour card for the bench
• Your own colorants and oils from your supplier's sheet, plus fragrance and additives
Lye is caustic. Wear gloves and goggles, add lye to water, never water to lye, and check any recipe before you pour. Pour Plan calculates lye, water and colorant amounts; fragrance limits and cosmetic labeling rules are yours to check.
