How soap gets made

From first pour to finished bar.

Four steps, the right supply for each one, and nothing you don't need.

  1. Creamy soap batter being stirred to trace

    01Step 1

    Choose your method

    Melt and pour uses a ready-made base, so there's no lye to handle and bars set within an hour or two. Cold process starts from oils and lye for complete control, then cures for four to six weeks.

  2. A stack of pastel handmade soap bars

    02Step 2

    Color & scent it

    Mica powders give shimmer and swirl. Use about 1 teaspoon per pound of soap, dispersed in a little oil or glycerin first so it doesn't clump.

    Calculate fragrance amounts
  3. Hands pressing soap into a pink silicone cavity mold

    03Step 3

    Pour into the right mold

    Silicone loaf molds are the classic choice for cold process. Cavity molds give perfectly shaped single bars with zero cutting.

  4. Freshly cut soap bars with blue charcoal layers

    04Step 4

    Cut, cure & package

    A wire cutter gives straight, even bars every time. Let cold process soap cure in a ventilated spot, then stamp, wrap and label it.

Small tips for better bars

Eight things experienced makers wish they had known sooner, and the supplies that make each one easier.

Marbled and speckled soap bars stacked on a light surface 01 / 08 Cut clean, even barsMost cold process loaves are ready to cut 24 to 48 hours after pouring, when they are firm but not brittle.
Shop soap cutters Stamped round soaps with an embossed pattern 02 / 08 Stamp while it is softPress a stamp into fresh cold process bars within a day or two of cutting for crisp, deep impressions.
Shop tools Flowers set into square silicone soap molds 03 / 08 Botanicals, placedSet dried petals in the cavity first, then pour. In melt and pour, a light spritz of rubbing alcohol helps layers bond.
Shop cavity molds A stack of white soap bars in dappled light 04 / 08 Melt and pour in an afternoonMelt and pour bases usually set within an hour or two, so you can pour, unmold and wrap the same day.
Shop starter kits Pastel soap bars arranged against a sage green background 05 / 08 Soft, earthy colorMicas and clays give muted pastels. Disperse colorant in a little oil or glycerin first so it does not speckle.

    What's the difference between melt and pour and cold process soap?

    Melt and pour uses a pre-made soap base that you melt, color, scent and pour, with no lye handling, and bars are usually ready the same day. Cold process starts from oils and sodium hydroxide (lye), gives you full control over ingredients, and needs to cure for about four to six weeks.

    Which soap mold should a beginner buy?

    A silicone loaf mold is the most versatile first mold for cold process. For melt and pour, a multi-cavity bar mold is easiest because every bar comes out finished with no cutting.

    How much mica powder do I add to soap?

    Start with about 1 teaspoon of mica per pound of soap and adjust to taste. Disperse it in a small amount of oil (cold process) or rubbing alcohol or glycerin (melt and pour) first so it mixes evenly.

    How long does shipping take?

    Most orders arrive within 5–12 business days, and items stocked in US warehouses often arrive sooner. Every order includes a tracking number sent to your email.

    Is the lye calculator free to use?

    Yes. Our soap calculator is free and needs no account. Enter your oils, choose a superfat and water ratio, and it shows how much lye, water and fragrance to use. Always double-check a new recipe before making it.

    Can I return something?

    Yes. If something arrives damaged or isn't what you expected, contact us within 30 days of delivery and we'll make it right. See our refund policy for the details.
