I bought a bag of CLEAR GLYCERIN (soap row…8.99 for 32 oz…use coupon = 5.00), 3 gel paste food coloring (Wilton row….AmeriColor…1.49each) in LEAF GREEN, ELECTRIC ORANGE, & ROYAL BLUE. I only bought bright colors, since they recommended they show up the best in the tub.
Other items you will need: microwavable bowl (glass is best), plastic spoon, long ice cube tray (mine is from Ikea, but many say you can get this same ice cube tray for water bottles at a dollar store. Target may carry them too), and optional Essential Oils (but I forgot to add mine in..oops.).
Melt about 3 cubes of the soap bar glycerin (clear kind only) in a glass container in microwave at 30 second intervals, until completely melted. (One cube of glycerin made about 1 3/4 tub crayons. 3 melted cubes, for me, made a perfect set of 5 bath crayons of the same color). So, I made 5 blue, 5 green, and 5 orange in batches and it took a total of 9 glycerin soap bars.
Next: Add about 1/4 teaspoon of the gel paste food color (the Pinterest blog commented that regular food coloring did not allow the colors to come off on the tub as well as the gel paste did). You MUST work quickly from the microwave, to the food coloring mixing, to pouring!!!!! This stuff starts to harden fast! If it begins to congeal while you are still stirring in your color, then pop it back in the microwave for another 20-30 seconds. Mix coloring as completely in as possible. Pour coloring into ice cube trays.
First row: the Bright Orange crayon, when tile and crayon are dry
Second Row: The Leaf Green crayon, when tile and crayon are dry
Third Row: (my favorite): The Royal Blue crayon, when tile and crayon are dry
But, completely supervised, I say this recipe is a keeper for me. Only a little food-dye residue on his hands after a long, colored-on bath. No big deal for this Mommy (well, “yet” anyways).
