I/ we have sent out a few frameworks to Nobel (Crco),and we are having a terrible time keeping the porcelain from cracking. When the porcelain fractures, it is down to the framework, and there appears to be a very heavy greenish oxide. This oxide layer looks nothing like any np alloy I have ever seen. I asked the rep to send/ email me the specific handling instructions, and all I got was the sales literature. If anyone here as any ideas, I would greatly appreciate the input.
We are surface finishing, luminous oxide blasting at 2.5 bar, steaming, then degassing the units before opaque.
Thanks in advance.
