Emax Yellowing

what if mine look fine after sintering but color up after glazing? Is that a different animal?

Yes, that's contaminated firing tray/pins and or your porcelain oven is contaminated. I will say for EVERYONE, don't mix/match your firing trays between metal and all-ceramic...if you do, you'll eventually get the yellowing. Order some new trays if that is the case.

I think the trays just might be the problem. I had a 3 unit bridge and where the pontic was closest to the peg, it was the most discolored.

Charles, the regenerative firing worked great! Thanks so much.
