[QUOTE="ts4341, post: 190842, member: 5961"] Brent... Why has SageMax promised a 7 layered zirconia for over a year and yet nothing is available? You can fast sinter Origin Live Zr 20-25c ramp speed. XT has a 15c ramp speed cycle but i have seen some units fail at this speed. The new super trans. zirconia needs slower times. Crowns: 8c up - hold at 900c for 30m - 3c up to (1450c) 2h hold - 4c down to 900c - 8c to 200c Bridges: 6c up - Hold at 900c for 60m - 3c up to (1450c) 2h hold - 4c down to 900 - 8c to 200c Different color liquids need different drying techniques also to create correct coloring.
