Introduction: How to Make Soap

To make soap, you need fairly few materials. The materials you do need are glycerin, a microwave, food coloring (OPTIONAL), a mold, microwave safe Tupperware/bowl/thingy to hold melted glycerin, and something to use to mix the glycerin and food coloring.

These are my responses to the Make-To-Learn contest (Directions are after these responses):

What Did You Make? I made soap. You use soap to wash your body. To make it, I used glycerin, a microwave, food coloring, a soap mold, a Pyrex beaker, and glass stirring rods.

How Did You Make It? The idea came from a science teacher at my school, who assisted me in making the soap. When we melted the glycerin, we had no idea how quickly it would harden. We had to re-melt it, and rush back to the molds to add color and pour it.

Where Did You Make It? I worked on this project in school. This project connected science and my personal life, because, using science, I was able to make an item that had added benefits to my skin when I  use the soap.

What Did You Learn? The biggest challenge during the creation of the soap was the speed at which the glycerin hardened. I am proudest of the fact that I was able to experiment scientifically in an attempt to benefit myself, which is the way that some of the greatest inventions were built. If I had to do this project again, I would move the molds closer to the microwave, so we would have more time to pour the glycerin.

Step 1: Melting the Glycerin

To begin, you take some glycerin and put it into the microwave-safe bowl. You then place it in the microwave. Put it in for 40 seconds, and then in 15 second intervals until it completely melts. When it comes out, immediately begin to stir it. CAUTION: The glycerin will harden in a very small amount of time if you do not stir it. If it does harden, just melt it again.

Step 2: Add Color

Put some drops of food coloring in the melted glycerin until the color is the desired "intensity". If you would like, you can fine chop some herbs and add them to the glycerin. Continue stirring.

Step 3: Pour the Glycerin

Next, you pour the glycerin into the molds. If you want to make a multi-colored bar of soap, repeat the previous steps for each color. Before pouring more colors in, make sure that the glycerin has hardened into a slimy, but solid mixture on each layer.

Step 4: Freeze the Soap

After you have finished pouring the soap, put it into the freezer. It should stay there for about 24 hours (One day). When it is done, take it out of the mold, and it should look something like the picture above.

To add.. glycerin is in liquid form and freezes at 17°C (62.6°F).

What you did was purchase a melt and pour soap base, melted it and added color, fragrance and let it solidify.

Glycerin can never be converted to soap but can be used as an additive to soap.

Hi Partick

Not sure what you made is really a soap. As per your instructions, you just melt glycerin and refreeze it.

How did glycerin after adding color and freezing change to soap?

What surfactant was added?

When was it added?

Too many confusions.

Did you add any scented herbs to make the soap smell nice? Or are these more decorative than practical? (These came out really nicely, btw. Though the soap bars seem to be a different shape than your mold. Google image search?)

Because the captcha is not working on my replies, regarding wilgubeast's question, yes, in order to make the soap smell nice, you could use finely chopped rosemary or another herb, or you could use the extract of the scent, such as vanilla extract I believe would work. I did in fact have to use Google image search, because I made the bars at school, and I had no camera.
