We make goats milk soap for sale--we have used it for years and decided to market it---DD made 6 batches yesterday--We make both hot process and cold process soap. Although hp soap can be used right away, we found it is better to wait a few days---cp soap really needs 4 to 6 weeks to cure unless you use some of the quick dry methods--- then you can get useable soap within a week. You should check with a lye calculater --hmm I am not sure of the site, cause my DD does that, but you should be able to google it. We use goats milk from our own goats, coconut oil, sunflower or safflower oil, lard, lye and EO or FO. We have unscented--unscented with oatmeal as well as about 50 fragrances some of them using essential oils. Had to buy more goats to keep it up--- each batch is hand made and hand cut--of course we have our personal stash ready. Crumbling may mean your temps weren't right. It may have "seized" Once you get started, it is sooo addicting. LOL. Have fun Carolyn
