[QUOTE="RDA, post: 299420, member: 6261"] I do have an exhaust fan above our sintering furnace, but I don't think it's a requirement. We use water based coloring liquids, so I'm not sure that if you are using acid based if you would get some odor. Also, check out Dental Direckt zirconia's, I believe that all of their zirconia choices sinter at the same high temp, 1450 C°. They offer some great choices too. [URL]https://www.daldttechnologies.com/supplies[/URL] One other "cheat" that I've done when sintering different zirconias, and it has worked out for us, is to place the higher temp sintering zircoanis in the upper tray, and the lower in the lower tray. I was told that the muffle platform of the sintering furnace can soak up to 30° from the lower tray, almost equaling out the two trays. I found this out when we first started this, because our zirconia was coming out to opaque since we were only using the lower tray for higher temp zirconia sintering. My theory, is upper tray at 1500 C°, lower tray must be at 1470 C° , which works out fine in our results. [/QUOTE]
