Totally get where you're coming from @ruby310, that patience is the hardest part. I learned my lesson the hard way last year trying to speed up a silicone mold with a heat lamp. The outside felt solid but the inside was still soft, so when I demolded it, the whole thing tore and wasted the master. Now I just set it and forget it for the full time, no shortcuts. Rushing really does just set you up to lose everything and start over. Your point about ruining the whole mold is spot on, it's never worth the risk.
