I'm new to the forum. I need help figuring out my bath bomb recipe.. I'm stuck... the very first ones I made turned out perfect.(they stuck together,they cured without cracking, and they have been in a local store and stayed hard and didn't turn soft) I added corn starch recently because I ran out of LAL(salsa) and I've had nothing but problems. (They won't stick together no matter how wet or dry, sometimes I can get them molded and laid out but then they crumble and won't hold shape, or they cure just fine for a day but the third day they have cracked and expanded. Some do really well but then they turn soft and expand when I leave them at the local store... I'm in school and in my spare time I come home and work diligently on these, I have more products I make but I want to perfect this before I move on.. I've posted them for selland people ask about them but I can't sell good ones at first and then the others not good at all... please help me ...I've posted pics below to show how they turn out and this is them in the curing process but after is a mess...
