Here is the recipe that i use. I found it at candle cauldron website. (want to make sure due credit is given to author) I reduced the sunflower oil to 2 Tbsp. because one of my customers stated it was too oily for her skin. I dont seive it, i mix my dry ingredients in a food processor. (when i gently sieved it, the corn starch went airborne. the result was I became instantly grey-headed and a mess on my table). ****************************************************** Bath Bombs Dry Ingredients: 1 C baking soda, 1/2 C citric acid, 1/2 C corn starch. Sieve dry ingredients til you get smooth. Wet Ingredients: 2 1/2 T oil (I like sunflower or soybean oil), 3/4 T water, 2 tsp body safe fragrance oil, body safe coloring, 1/4 tsp borax. Combine wet and borax in a jar and shake. Drizzle onto dry ingredients and blend. I get right in and mix with my hands using disposible gloves. Pack tightly into molds and slide out. Dry overnight and package. I use the pull apart clear plastic ball molds (from Michaels) for mine. A hint on filling is to fill as full as you can get (packing as tight as you can). I then tap on the back lightly with the end of a table knife and this seems to loosen the bomb and make it come out easier. Once inawhile I break one while unmolding, but I simply repack and start over. I have tried a lot of bath bomb recipes and this is my favorite. JanL
