[QUOTE="JMN, post: 294941, member: 8469"] Did you mix these up in one batch and then pack them all at the same time? The last one packed can have some oddness if it takes too long. The two things I know can cause this: A) Using cold cure liquid with heat cure powder. I know someone that had issues bench bottle got refilled then it was noticed. Label EVERYTHING. I use cheap sticky nametags from the dollar tree/everythings a dollar stores. [ATTACH]31486[/ATTACH] B) Not having enough material in the flask. It's not enough to fill the void when packing. You must compress the acrylic, not just fill the negative. I had one that had this issue. It was Original shade and looked slightly more orange and had pinhead bubbles. When I packed it I thought, "Hey, this will be the first one with no waste, great!" as I barely had any flash on the first pack and with that I closed on the second compression. This issue was the result. You need to overpack. Significantly. My solution for this was to rebase. I process on a dup model, so I still had the original and made a new processing dup. Then coated the original with ADS's APS separator and waxed the teeth to the ridge enough that I could be certain of a perfect transfer and then completed the waxup on the dup. Then redid the whole pack and cure. This time with 2x the standard 10ml to 21g. Yes, I weigh it out instead of going by volume. It's worse than sifting flour, you never get the same measurement twice with this stuff. [/QUOTE]
