I've been making soap for a little over a year and I'm stil not certain about a few things. I've been putting TD in my oils before I even dump the lye and that works fine. I've already seen opinions that say that waiting for trace to put in your overfat in CP is hooey. I've also seen a few people that say that mixing a castor oil with your scent and dumping at trace will make the scent hold better. That sounds like hooey. Still since my overfat is usually 5% castor oil, I mix it with the scent and dump at trace. Assuming it's not an accelerating scent, is there any reason not to put everything together at the beginning and go? The next question is about metal in contact with curing soap. I only recently heard that might be a problem. Several months ago, my son-in-law made me a rack to cure my soap. The soap is sitting on 1/4" hardware cloth (like heavy duty chicken wire with 1/4" square holes). I've cured a fair amount of soap on it. It works great and I'm not seeing any ill effects. Am I missing something?
