Just getting into the wonderful world of soap making? The soap making process can be intimidating at first with a long list of ingredients and supplies. We’ll go over the three main soap making processes plus an essential list of soap making supplies for beginners. When you’re just starting out, don’t blow your budget on getting stuff you don’t need yet. Start small and go from there.
The three main soap making processes
If you’re new to soapmaking, it’s important to know the three main methods of making soap. Each process involves slightly different supplies and materials. We’re not going to get into too much detail here, but here’s a quick overview:
- Melt and pour: This is the easiest method that many soapmakers begin with. It involves melting a premade soap base, adding in any essential oils or other add-ins, pouring into a mold, and allowing the soap to harden. You don’t need to worry about handling lye with this method as your premade soap base has already undergone saponification. Soap is ready to use in a matter of hours.
- Hot process: A method of making soap from scratch that involves handling lye. The application of heat speeds up the saponification process. Soap bars require a curing time of about 1 week.
- Cold process: A popular process of making soap from scratch that also involves handling lye. Cold process soaps allow for a great degree of customization. Soaps require 4-6 weeks to fully cure.
At its simplest, a natural bar of soap contains just three ingredients: lye + distilled water + oil/fat.
That’s it!
Melt and pour soap making supplies for beginners
If you’re planning on getting your “feet wet” so to speak, the melt and pour method is a great place to start.
You don’t need to worry about handling lye as this has already been done for you. This is a great method of soap making as it’s also safe for children to help with.
There are plenty of melt and pour kits you can buy that come with everything you need to get started. Or, you may prefer to buy your own items individually.
Here’s a basic melt and pour supplies list:
- Molds: You can buy either a loaf mold, or a silicone mold. Loaf molds require cutting each individual bar of soap. They come in different sizes so ensure you’re using the right size for your soap recipe. Silicone molds are individual molds which require no cutting, but more pouring. You can also make your own, or use other household objects like an old milk carton, or a bread loaf pan (so long as you line it first).
- Soap bases: You’ll need a few melt and pour soap bases. A few common bases include glycerine (for making clear bars of soap), Shea butter, cocoa butter, olive oil, honey, and goat’s milk.
- Thermometer or temperature gun: This helps you carefully monitor the temperature of your melt and pour base and avoid burning it.
- Rubber spatula: Handy for mixing and scraping out the melted soap base into the mold. Since you’re not dealing with lye, you can really use anything to mix with such as a wooden spoon.
- Rubbing alcohol (Isopropyl alcohol), in a spray bottle: Used to remove excess air and prevent bubbles from forming in the soap.
- Heat-safe glass measuring cup: Many melt and pour recipes use a microwave to warm up the soap base. It’s easy if you can just chop, measure and heat the soap base using one container.
- Heat-safe large bowl: For mixing your soap with any fragrances and add-ins.
- Measuring spoons: Just any standard measuring spoons/cups will do.
- Essential oils or fragrances (optional): Part of the fun of creating your own handmade soap is customizing it with your favorite scents. A few good versatile essential oils include: lavender, peppermint, and lemon.
- Something to melt your soap base: You can use a double boiler, slow cooker/crockpot, or microwave.
- Cutting board
- Knife
- Add-ins (optional): Add-ins include natural exfoliants (such as coffee or oats), and any herbs and botanicals you’d like to include.
- Colorants (optional): You may choose to use natural vegetable or plant-based dyes as these are gentler on the skin.

Safety equipment
If you’re planning on making any soaps using either hot process or cold process methods, you’ll need to invest in some basic safety equipment to protect yourself from lye.
Lye is a caustic alkali compound that can cause damage to eyes, skin, and the respiratory system if inhaled. Ensure you work in a well-ventilated room away from small children and pets.
Please read up on lye safety BEFORE diving into soap making. If you’re wondering if lye is safe to use in soap and cosmetics, check out our post here.
Safety equipment supplies list:
- Safety goggles
- Protective gloves (rubber, latex, or nitrile)
- Long-sleeved shirt or lab coat
- Apron
- Oven mitt
- Protective mask
- Well-ventilated working area
Cold process and hot process soap making supplies
For hot process soap making supplies, it’s essentially the same as cold process, except you would also need a slower cooker/crockpot.
Tip: Avoid using glass mixing bowls or measuring cups for your lye solution. Over time, lye corrodes and etches glass—you don’t want a dangerous lye spill from a broken glass container!
- Lye: Lye applies to both sodium hydroxide (NaOH) and potassium hydroxide (KOH). Chances are, if you’re making hard bars of soap using cold process, you’ll need sodium hydroxide. Read more about the differences between sodium hydroxide and potassium hydroxide here.
- Scale: While you don’t need anything too fancy, a digital scale that measures in both ounces and grams is a lifesaver. When following soap recipes, taking accurate measurements is vital.
- Immersion blender (aka stick blender): It’s super-handy to have an immersion blender that you can just stick into whatever container you’re using to blend up your soap.
- Thermometer or temperature gun: An accurate thermometer helps you keep track of the temperature of your lye solution and other oils.While you need at least one thermometer, it’s handy to have two. This way you can accurately measure your lye and water mixture, plus your fats/oils at the same time. Or a temperature gun will do the trick.
- A big ol’ stainless steel pot: Stainless steel does not react with lye. Make sure you have a true stainless steel pot (not one with a metal blend of aluminum). You’ll use it to melt your oils and blend your soap mixture. Aim for one that holds between 8-12 quarts.
- Several plastic bowls: It’s handy having a few heat-safe plastic bowls. Look for either #5 (polypropylene) or #2 (HDPE) on the bottom of the container.
- Plastic pitcher with a lid: Same type of plastic (#2 or #5). You can also use a 100 percent stainless steel pitcher if you prefer. This is good for mixing your lye. A pitcher that holds 2 or 3 quarts works well.
- Small bowls or containers: To hold your various fragrances, essential oils, colorants, and other oils/butters.
- Molds: We touched on the different types of molds above in the melt and pour section.
- Soap knife: While not absolutely necessary, if you’re planning on using loaf molds, soap knives come in handy. You can also get fancy with a “wavy” knife.
- Plastic or stainless steel spoon: For mixing your lye solution.
- Heat-resistant silicone spatula: For safe mixing.
- Heat-safe glass measuring cup: Pyrex makes good reliable measuring cups that are easy to clean.
- Metal whisk or small spoons: Used to blend together fragrances and oils.
- Ladle (plastic or stainless steel): Handy for scooping out your soap mixture.
- Clean dishcloths or paper towels: Because there’s always a spill or two!

How to store soap making supplies
As a general safety rule, it’s best to use your soap making supplies just for making soap. This includes any pots, blenders, spoons, whisks, bowls, etc.
Personally, I don’t even like the idea of lye touching the same utensils as something I would put in my mouth!
As for storing your soap ingredients, lye needs proper storage:
- Store lye in an airtight container.
- Store lye in a clearly labelled container (this is usually the original container typically made of HDPE plastic).
- Keep in a dry, dark, cool place out of reach of children and pets.
As for your other soap making supplies, try to:
- Keep an inventory of ingredients you currently have.
- Group similar items together (for example essential oils, or natural colorants) to stay organized.
- Label everything!
Other soapmaking FAQs
Is fragrance oil the same as essential oil?
No, they are different. Essential oils are extracted from natural flowers and botanicals. Fragrance oils are typically man-made, or synthetic. You won’t derive the same benefits from fragrance oils as you would with essential oils.
Some fragrance oils are labelled as “natural” meaning they are derived from natural components, however these are still made in a lab. Essential oils are pricier as they have more therapeutic effects. Fragrance oils often have a longer shelf life and are less expensive.
Can I melt down a bar of soap and remold?
Absolutely! Melting old bars, or leftover scraps of soap is a great way to reuse or upcycle the stuff in your home.
If you’re melting a new soap base, this would fall under the melt and pour method of soap making.
Is melt and pour soap considered handmade?
That really depends on who you ask. If you define “handmade” soap as something you make with your own two hands, then melt and pour would definitely fall under this category!
However, some soap purists would argue that since melt and pour soaps are made from premade soap bases, they’re not truly made-from-scratch as hot process or cold process soaps.
But really, who cares? If you go through the trouble of sourcing high quality, natural ingredients for your batch of soap, that finished product is still good in our humble opinion.
Have fun with soapmaking!
