Need your help on this... My last 3 batches of bath bombs were perfect for about 1 week, then crumbled. However, bombs I made 2+ months ago (when there was no humidity) are still perfect. All are stored in the same room, with a dehumidifier, but humidity is really bad this time of year. Is it true that bombs that were dried with low humidity cure properly and will stay solid? But if the bombs dried with higher humidity, they will crumble?
Do any of you have experience of drying bath bombs in an oven? I read to get the oven to 170 then turn it off and let the bombs sit in it overnight.
The only other thing I can think of is the freshness of the citric acid. It still fizzes, but can it go "stale"?
