Very good points about leakage and the fact that it will make 60 - 70 bars. I've never used the inserts, so I don't know if they'll leak. I don't even know if the mold will actually HOLD 20# of batter. I've only used it once for a 5# column pour. I did test it out by putting three 7# bottles of oil in there and jostling it up and down. The bottles didn't make the bottom fall out. That's a good thing in a soap mold, right?
I actually chickened out after I posted this. I pulled up my Bastile recipe and discovered I used tallow, not lard. I don't have enough tallow to make a 20# Bastile. So, I'm going to do a 1# lard Bastile and a 1# tallow Bastile with no fragrance. I'll let them cure side by side and compare them after six weeks. The one I like the best is the one I'll make in my monster mold. Then, I can let them cure for a year and sell them at the yard sale next August. If they develop DOS or something else goes wrong, then I'll toss them and start all over. It's just soap.
I figure I've got seven years before I can retire. I'll get into panic mode in six years if I still haven't figured out how to make a product that will support me when I don't have a nice cushy job anymore. Actually, if I can't figure this out in six years, some one better shoot me and put me out of my misery. :smile:
ETA: I'm sorry Stacyspy! I should have put mega mold or behemoth.
