Update from last night...I tried so hard to wait until the soap got down to 140-145 but it took sooo long! I think I waited at least 15 min. for it to cool off with the lid on on the crock because I didn't want the soap to dry out, and it was taking soo long, so I got impatient and added the eo's at 160-165. It didn't evaporate like it did the other night, I mean I'm sure it did a little, but not near as much. Also, even with an 80/20 lavender/lemongrass blend, I still only smell lemongrass! I put in 5 grams of lemongrass and 20 grams of lavender, and all I smell is lemongrass - that stuff is soo overpowering!
