I have designed and built a prototype mold that works great for M&P. It occurred to me that it might work for CP, so I'd like to test it with CP. However, I have never made CP soap, and I would rather not go to all the trouble of making one batch just to test if I don't have to. Question: would the test be valid if I used re-batched CP rather than a batch from scratch? That is, would the mold know if I poured re-batched or a batch from scratch into it? Thanks.
