yay, today was a great day for bombs. I used Lee’s SLSA recipe but did substitute Sweet Almond Oil for Grapeseed Oil and added TBL Colloidal Oatmeal. The humidity in my studio was 48%, 100* weather outside; and viola the bombs came out perfect using the extra small sphere, hearts and a few large spheres. I live in central California. My compressor was at 78 PSI, my mix was grainy & on the dry side. They worked perfectly. I wish we could post photos here.
