[QUOTE="doug, post: 307799, member: 1835"] This may not help now, but here's my process. I sprinkle shoulder power on the last opaque coat before firing. I use shoulder powder to fill under pontics and in the interproximals. This helps keep the porcelain from pulling so much when layering the dentine. i place on firing table at 400'C with a 6 in entry into the furnace. I have an 8 minute cooling when the furnace opens. Yes, I still get some tears and some margin pulls, but it has been a big help in reducing it. All of the crowns, base metal or semi-precious, are fired using the same program [/QUOTE]
