Wardbond, are you a fan of the actor? I loved Wagon Train, but Ward Bond in any movie was always one I would watch.
That's very courageous of you to boil your own mud to use for soap making.
I can't even imagine a heating pad that would get so hot it would turn CP soap into HP. Sometimes my heating pad gets too warm for my body, though, so I suppose some can get too hot. Does it have a lower setting? If not, I would probably not use that heating pad on my body ever.
Skatergirl46, you have The One Mold!? Wow, I am impressed. I've seen it, but it is so expensive, I would not be able to justify the expense. How do you like it so far?
Lin19687, some other soapers here have used bacon grease before apparently without any issues, so I don't think it's a problem. SoapQueen posted this on the How to Render Bacon Grease for Soapmaking:

And actually using used cooking oils for making soap is something done in many parts of the world, so I don't think it's a bad idea, as long as impurities are cleaned out and all other good soaping practices are followed.
