Anyone here have any experience with doing this?
Curious as to results and cost of the furnaces also

You can only use for singles on quick cycle everything must be bone dry and the crown doesn't look as good I checked this out 2 years ago at ZZ.Overall its not quite there yet

It's being used for industrial purposes...where esthetics aren't of importance... Linn High Therm has a dual frequently dedicated furnace for that...not sure how it would work for dental. ..

Zirkonzahn already have working models but when I saw them I don't think they were quite there yet .The difference in time to fire by micro wave and traditional furnace for anything with a bit of thickness was very little and the trad furnace crowns looked better.
