BATH SALTS 
2 cups Epsom Salts 1/2 cup rock salt or sea salt 4-5 drops oil of essence 2-3 drops coloring 
Put salts in a bowl.  Add coloring and mix until you have the desired color. Add  oil of essence and mix well. Put salts in a large clear jar or bottle. Use 1/4 cup salts in a tub of warm/hot running water. 
***  The oils you use, are ones that can be found at craft stores and used in soap making. Same thing for the coloring. You may also use food coloring if you wish. I use rubber gloves (you can find them at craft stores and they are gloves like doctors or food service  workers use) and mix this all by hand. I also use a glass bowl for mixing the salts in.
