A few weeks ago I saw a very beautiful cold process soap online and immediately started wondering how I could create a similar effect using melt and pour. Here’s what I came up with!
About 3 pounds of White Melt & Pour Soap Base to which I added:
About 3 ounces of Liquid Glycerin. This makes the soap more malleable and helps prevent the layers from splitting apart when the loaf is cut into.
About 2 pounds of Clear Melt & Pour Soap Base to create my 6 colored blocks.
These liquid colorants: Non-Bleeding Cherry, Liquid Orange, Yellow Jelly, Liquid Green Oxide, Non-Bleeding Teal, Liquid Violet. The colors are up to you! You can try one or two colors, or as many as I did!
To start, I used a multi-bar rectangular silicone mold to create the colored soap out of which I would be making the shavings. Each bar was about 4 oz which made more than I ended up needing. I used clear melt & pour base with liquid colorants. My plan was to incorporate all six colors, but I ended up running out of room and using just five. Remember, the colors you use and the order in which you layer them is totally up to you! Get creative!
For this project I used a 10″ silicone loaf mold which holds 3 pounds or 48 ounces of soap. With 48 ounces of soap and the 6 colors I wanted to use, I gathered that each layer would need about 8 ounces of white soap. However I didn’t end up weighing the shavings and subtracting that weight from the total. This is why I “ran out of room” and couldn’t fit the purple layer. The amount of shavings and therefore amount of color is entirely up to you! If you just want to play and see how it turns out, go for it!
The next part is creating the shavings which I thought was really fun! I used the largest size on a standard cheese grater. The shavings wanted to cling together so I simply spritzed them with rubbing alcohol in a bowl. This allowed them to separate and made them easier to handle.
Melt your white soap and add the liquid glycerin. To keep the shavings from melting instantly you must let the soap base cool down to about 130 degrees. I used the same mini temp gun we use in cold process soap making to check the temperature. (If your soap IS too hot and ends up melting some shavings, I say go with it! See what the end result is!)
I sprinkled a layer of pink soap shavings into the bottom of the mold (1st photo below). I poured very slowly in a thin stream back and forth from one end of the mold down to the other until I covered the shavings to my liking (middle photo). I put the mold in the refrigerator until the layer was set, then started again by sprinkling the orange layer next (3rd photo).
Repeat with as many layers as you have!
When I was finished, I left the loaf in the fridge until it was cool throughout and it came out of the mold easily.
Cut into your new soap and see what you’ve made!
