That's never happened to me. I find these take at least 5 minutes to reach thin trace with generous stretches of continuous stick blending. That's with different batches and types of CO (76 and 92).My 1.5 oz individual molds will full gel with 100% CO soap even with only 38%. Even sitting on the lid of the washer uncovered. And it takes about 3 short bursts with the stickblender to get thin trace. You should not try for medium trace, you will barely have time to pour at thin trace.
If you imagine the mold in two halves, it started in the center of each half (slight overheat bulges) and met in the middle. This is still visible in the photo. Gel was almost complete but there was a thin halo.Did it make it all the way out or leave ya with the "halo effect"?
