FIRING PARAMETERS & BASIC OPERATION
-Standard-
① Steps
Color comparison → impression → CAD design → grinding for 15~35 minutes (due to the specification difference of the restoration) → glazing or enamel → sintering → inspection → bonding
② Sintering procedure（Take the E.MAX P310 porcelain casting furnace as an example. Different sintering furnaces have temperature deviations and need to be fine-tuned according to the actual situation.）
The processing takes about 25 minutes：
③Start at 450°C, put in the restoration to be sintered, last for 2 minutes, heat up at a rate of 30°C/min, the temperature rise time is about 12minutes (750 seconds), heat up to 850°C and hold for 7minutes (420seconds), then open The cover is directly cooled by air.
④ If you need to glaze a second time, the corresponding glazing procedure：Start at 450°C, put the restoration to be glazed, dry time 2 minutes, heating rate 50°C/min, heating time 7minutes (420seconds), heating to 800°C for 2 minutes (120 seconds), and then directly Adopt air cooling.
Special Note：
There may be a shrinkage rate of no more than 0.2% during the sintering process, which must be fully considered in the design software.
If the glazing and sintering steps are combined, use the procedure ③ to operate. If the sintering and glazing are used in a step-by-step manner, use the procedure ③ for sintering first, and then use the procedure ④ for glazing.

③Start at 450°C, put in the restoration to be sintered, last for 2 minutes, heat up at a rate of 30°C/min, the temperature rise time is about 12minutes (750 seconds), heat up to 827°C and hold for 4minutes (240seconds), then open The cover is directly cooled by air.
▲Can be used or not used Object Fix Flow. If you use Object Fix, please select IPS Object Fix Flow.
④ If you need to glaze a second time, the corresponding glazing procedure：Start at 450°C, put the restoration to be glazed, dry time 2 minutes, heating rate 50°C/min, heating time 7minutes (420seconds), heating to 800°C for 2 minutes (120 seconds), and then directly Adopt air cooling.
