Bath bombs are relatively easy to make. One of the most important things to do when making bath bombs is to have all the ingredients organized and within reach, especially once you have started mixing the ingredients together. Once you have the basic ratios and techniques mastered for making bath bombs, it is easy to vary the recipes in so many ways.
Bath bombs are made using the following basic ingredients:
This recipe makes about 2 cups of product. This recipe can be doubled or quadrupled, etc. Just remember the ratios.
1 cup baking soda (bicarbonate of soda)
½ cup corn starch
½ cup citric acid
powdered colorants (a drop is good enough; you do not want the bath bomb too dark)
1 Tbsp water or witch hazel
2 Tbsp almond or other oil (oils that are solid at room temp may be used but will have to be melted and cooled first)
½ - 2 tsp fragrance oil or essential oil
Prepare and measure ingredients. Cornstarch and baking soda may have to sifted to get rid of lumps. Make sure that work area and all the tools used are dry. One drop of water touching the citric acid can start a fizzing actions way before needed so keep the citric acid especially away from liquids.
Mix all dry ingredients together in a deep bowl. Mix wet ingredients together and add slowly to the dry ingredients. Do not saturate the dry ingredients too quickly. Turn over ingredients as you mix them so that one area does not become too saturated. Alternately, a large dropper maybe used to add the liquids in tiny amounts.
Shape into a large ball or two smaller balls. Pack mixture tightly into bath bomb molds or form them into freeform balls. Packing mixture tightly ensures that the mixture will be intact when it is removed from the mold. Fill one half of the mold with mixture, then the other half and squish the two halves together tightly. Then tap edge firmly to release the bomb from the mold.
Leave on a lined cookie sheet or lined shallow box to dry out for 12-48 hours. Cover the bombs with a dry kitchen towel to protect them from humidity.
These optional ingredients may be used to give that extra something to an already fantastic product or gift.
