So I have seen this asked in different words but I'm going to ask again because I am still having issues! I've been using the same bath bomb recipe for almost 2 years and it's deciding that it doesn't want to work right anymore! They expand and bubble, ok I understand that to mean they were too wet. Try less liquid (at the time green tea or water) and they crumble. And I really loved this recipe in the beginning and never had any issues so I think well its not the recipe it's me. I've also recently moved so I thought maybe this house is too humid. So I see a demo for a bath bomb press (just the hand held) and she used alcohol claiming water is too wet. So I try 99% isopropyl and added some bentonite clay and let them set over night and when I checked them they were not even crumbly the mix was still soft and sandy in the mold. So I dumped it out and tried redoing it with a mixture of water and witch hazel. The **** things blew up! I don't understand what is different if it'd the altitude or the air in this house which is wood stove heated so you'd think it would be quite hot and dry in here. I'm at my wits end and it sucks because bath bombs are my best selling items. Can anyone help or am I asking on a really outdated forum?? That would be my luck haha.
