In my experience, vanilla discoloration in bath bomb is inconsistent and takes longer to appear. For example, in cold process soap, vanilla discoloration happens within days or even hours. While in bath bombs, the vanilla discoloration may not appear until weeks or months later. You can add Vanilla Color, but keep in mind it may not prevent the discoloration. To be on the safe side, you’ll want to use a fragrance that doesn’t discolor. Find our clear and vanilla-free fragrances here.
What molds are best for bath bombs?
One of the most popular bath bomb mold options are two-part molds that create a spherical shape, such as the Stainless Steel Bath Bombs Molds or the Bath Bombs Mold & Package. If you’re looking to create bath fizzies with a unique shape, best kind of molds to create bath bombs are sturdy, yet slightly flexible. Plastic Molds with individual cavities or Heavy Duty Molds are great options. Silicone molds are an option as well. The Round Silicone Mold makes adorable bath bomb cupcakes, as seen in the How to Make Bath Bomb Cupcakes.
I recommend leaving your bath bomb in the mold for at least several hours, up to overnight. If you try to remove the bath bomb while it’s still soft, it can crumble. Allowing the bath bombs to dry thoroughly in the mold will make it easier to remove and handle.
