How much slsa in a bath bomb

[QueensCandlebtq]

Do I need to use Epson Salt if I use SLSa? My logic was that the Ep. Salt was to harden the bomb and the SLSa is to create bubbles and condition. Any input would be greatly appreciated.

Hm. So I tried a batch with only 2 tb of slsa and they still turned out with the same weird dusty/crumbly texture. I was positive it was the slsa that was causing it, but now i'm not so sure. I'm not having any issues with cracking or breaking but i'm wondering now if the mixture is still too dry or that i'm not packing tightly enough. Would either of those cause the crumbs?

Check your humidity it can make your bath bombs fail! If you have a machine to help with the humidity try to keep it at about 42 and they should come out great
