This is how I make my homemade soaps that I sell at PoseyCorner.com. 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.
