Had a talk with daniel from garland dental, in trying to figure out why I was blowing elements every 6 months, he explained something we all know, that muffles absorb water.. porcelain ovens stay on constantly, but most sintering ovens dont have night modes or get used every couple days.. When it heats up with water, these elements snap

Hello!
I am trying to sinter Katana STML in an Ivoclar Programat S1. The firing temperature does not go past 1530 Celsius, but the STML's "required" firing temp is 1550. How do we adjust and is it possible to have a firing time that is less than 8/9 hours? I understand faster isn't always better, but just curious.

STML needs 1550. Trying to cut the time short compromises color.

Call Origin and see if they'll send you a free sample of thier Beyond Plus Multi zirconia, it sinters at 1500.

Someone recommended a regeneration cycle to me after grinding on sintered zirconia. I cant find an actual firing for this. I am assuming this will be done in my porcelain furnace but then I had a thought that maybe it was a sintering program they were referring to. Suggestions would be greatly appreciated

Were they looking fine and now they don't? Are the lot numbers different?
Are the ones looking unsintered all the same brand/shade/maker/translucency type?
Are some in the same sintering batch looking fine and others not? Are they ones looking bad always in the same area of the oven?
Have you changed materials?
Have you had a power outage recently and now they all come out looking odd?
When did you last calibrate?
How old are the elements?

Lots to check before assuming anything from a picture alone.

Thanks JMN, they were all from a Katana puck. No recent power outages. I will check the other issues and see what I discover. I’m retiring soon and I’m trying to let the young techs take care of all the new technology, but they presented me with these. I appreciate the help!

Eureka! They were sintered on the wrong program. Takes an old guy to go look at the ovens

That's rolled up newspaper level to get someone else to detect that. Time to teach troubleshooting to the newbies.
Ha! I just want to retire. We had a fine discussion about procedures
