Please help I'm new to bath bomb making and I'm on my 2nd batch but they are going like sticky sand in molds after 12 hours. I'm using 1cup baking soda 1/2 cup citric acid 1/2 cup Epsom salts 1 tsp olive oil 1 tsp polymer 80 1 tsp essential oil 1 tsp mica powder. The mix looks like slightly damp sand but after being in mould for 12 hours when I try ed removing it it split in half and was like damp sticky sand.... please please help.....thank you
