Does anyone find it helpful to pre-mix a base of your most basic bath bomb ingredients to store and keep on hand or would it be detrimental in some fashion? I am wondering if I could get away with mixing my baking soda, citric acid, epsom salts and SLSA and storing it in an airtight container. I think this would save me a little energy fibro - wise every time I make bombs, as I always use the same base. The different additives could then of course be put in at the time of making. I prefer to wet my mixtures in small amounts at a time, anyway, as I think mine just come out better that way as opposed to spritzing a huge bowlful.
