Here is what you need:
Here is the recipe I used:
1 cup borax
1 1/2 cup baking soda
1 1/2 cup washing soda
1 bar soap
1 quart of water to melt the soap in. 2 gallons for later.
1 5 gallon bucket.
First, grate the soap. A box grater seems to be the best way to do this, just be careful when you get to the end of the bar!
In a large pot, heat 1 quart of water, and add the grated soap. Medium to medium high worked the best.
You have to constantly stir this until the grated soap is melted, and do not let it boil. I noticed the soap tended to stick when I stopped stirring to measure out the other stuff. I didn't take a picture (oops), but in a large bowl, add the borax, washing soda, and baking soda together. When the soap is completely dissolved, take it off the heat and add in the dry ingredients. Stir this in really well- I ended up using a whisk to make sure everything was incorporated as it should be.
After everything is mixed together, pour the soap mixture into a 5 gallon bucket, and add 2 gallons of water and mix well. Because I was worried about whether or not all my stuff was mixed well, I stirred it in the bucket for a long time.
I had some help....
This is what I ended up with.
I'll make sure to post again tomorrow on whether or not my soap was a success!
