Step 1: Get It Together
Epson Salt - Pharmacy, Wal-Mart...
Glycerin - Pharmacy (I got mine at Wal-Mart)
Baking Soda - Almost anywhere
Cheese Clothe - Grocery Store or craft section at Wal-Mart
Water - Plain old tap water will work great!
Essential Oil(s) - Craft and Hobby stores, also check Wal-Mart (for Scent)
Large Sauce Pan
Mold or Form of some shape...
Step 2: Make With Tha' Mixin'
Step 1: Measure out 2 Cups of Epson Salt.
Step 2: Add 2 heaping spoonfuls of Baking Soda
Step 3: Mix dry ingredients
Step 1: Measure out 4 to 5 teaspoons of Glycerin
Step 2: Add 4 to 5 teaspoons of water
Step 3: Add Essential Oil... The amount of oil you use is entirely up to you. Just don't make it too strong.
Step 4: Stir all liquid ingredients until well blended.
Step 1: Pour liquid mixture onto dry mix
Step 2: Stir until well blended. The mix will be like wet sand or icy snow.
Step 3: Bringin' the Heat!
Heat the mixture on a medium low setting (electric stove), low (gas stove), or bake @ 250 degrees. The mixture will begin to melt and get glossy. It will also begin to expand... Keep this in mind for later.
[Edit / Revision] The mixture can be heated in the microwave in a microwave safe dish for roughly 1 minute. Micro wave heating melts the mix but it seems to cool quite a bit faster if "nuked."
Be patient while heating. Stir constantly and don't heat the mix too fast.
Once the mix starts to look like cream of wheat or warm tapioca pudding you're ready for the next step.
Step 4: Taking Shape
Carefully pour the heated mixture into the mold. Be careful the mixture is quite warm... Also the mixture will continue to expand for a while so only fill the form 1/2 to 3/4 full.
You're done just about all you can for now... set things aside and let them cool.
After the top of the mixture is cool to the touch, flip the mold over on to a cookie sheet or other hard surface. Gently tap the form to release the bath salt chunk. Slowly and carefully peel the wax paper or cheese clothe from the chunk.
Allow the chunk to cool for another 5 to 10 minutes.
You're now ready to cut the bath salt into bars.
Using a sharp knife carefully cut the block into the desired size bars, then leave them to cool some more.
Step 5: Wrap It Up!
If you use clothe cut a cardboard box to serve as a base as the salt is VERY fragile...
Well that's about it for this project, so enjoy your bath!
