Picture of Handmade Hot Process Soap

This is how I make my homemade soaps that I sell at There is no real secret to it. Soap has been made like this pretty much for centuries just with different tools.


Fair warning- After I made my first batch of soap, I was hooked. I went out and got more Lye. I ordered more Scents and colorants. Oh boy it can get expensive if your not watching yourself.


Warning: This process involves using Sodium Hydroxide. Otherwise known as Lye. AKA: Drain Cleaner! Use safety precautions! This stuff burns severely when active.


I am going to pretty much walk you through how I made my latest batch of soap. This one I decided to make a round Melt and Pour bar in Orange. I am not going to cover all of that. I just used some Orange Oxide to color some M&P Soap and Poured it into a ½” PVC Pipe.


Hot Process is almost the same as Cold Process. HP just takes it a step further with cooking it the rest of the way.

Step 1: Tools

Picture of Tools


A Scale that reads in Ounces to at least 1 tenth of an ounce. (Example - 1.4 oz)

Electric Stick Blender – You could use a Plastic or wooden Spoon to stir with but you will get tired of that.

Glass Measuring Cups

2 Plastic Measuring Cups – these will be used for the lye and lye water only.

Steel Table or Teaspoons – Used only to scoop out Ingredients out of the containers or Mixing up the coloring. I do not touch the lye with them.

Bamboo Skewers – I use one to stir up the lye into water

Parchment Paper – to line my mold

Wooden Mold – I made myself. You can use other things so you can search for it and get creative.

A Crock Pot – Mine I believe is a 5 Quart. With as small a recipe I use, the soap does not rise out of it during the gelling phase.

Plastic Serving Spoons – Plastic is key. You cannot use Aluminum where it can contact Lye. You will waste the batch that way.

Safety Glasses and Chemical Resistant Glove – In case lye wants to splash on you. You will know when it does.

Bottle of White Vinegar – This helps make the lye inactive if it spills on you or something. I also use some in my Lye and Lye Water Cups before cleaning.

Excellent demo, I learned through a Youtube video, but your explanation and picture demo is just as good. I haven't done anything fancy yet like embedding a soap bar in the mixture, but I am definitely going to. I'm making soap now as I write this and I will be taking your tip on how much essential oils or fragrance to add, I found this info. to be kind of obscure in my research, and as a result have had little or no smell to some of my soaps, definitely a trial and error type hobby, but I Love it!! So much so I started a home based business too, and yes it can get quite expensive if you don't watch it. Thanks again. Well done :)

You have inspired me to go HP all the way! Love your vivid color choices too. I would buy that instantly.

Thank you for sharing your process! I successfully made my first batch of soap using your instructions!

Congratulation. I hope these instructions were clear enough to leave you without any questions on the making process itself.
I was getting concerned that it was taking too long to get to trace, but I just needed to be patient! It took about half an hour for me.
