1. Grate the bar soap. You can get a good arm workout in grating by hand with a cheese grater. Or you can chop up the soap into 4-8 pieces, toss in your blender and pulse until you have small crumbles. I used the blender.

2. Pour water into a large pot. Ensure there is at least 2-3 inches between the top of the water and top of the pot. Boil the water for one minute (See Note 1). Turn burner to low.

3. Allow the water to cool for a few minutes, then pour in the grated soap. Gently stir to dissolve the soap into the water. It should dissolve in a minute or two unless you had large chunks of soap. Those took about 5 minutes to dissolve. Turn off the burner.

4. Add the glycerine, vitamin E and essential oils if using. Stir to distribute.

5. Let sit several hours or overnight to cool. The soap will remain very watery, but still works like soap! Some of the soap may separate (cloudy at the bottom of the bottle), just give it a quick shake before using.

6. Pour into your soap dispenser and enjoy!
