Hey Everyone, so ive read through a bunch of threads on cracks in your zirconia after sintering. After reading honestly I think Im more in the dark than before. Ive read it can be my milling machine, sintering beads, oven calibration, drying time and manner, ETC....... We have been milling for over a year with only minor issues. 2 days ago i had a #8 on a 8-9 splint crack right where the spruee was then a singe full contour crack on a cusp now this morning I had a 8-11 framework crack where the connector met the coping. We have a Roland DWX-51D, Brand New Burs, No Recent Power Outtages or Errors. We have a WhipMix Infinity ZR oven 6 months old. I use a toaster oven to dry 300 degrees for 20 min. We use Whipmix Vericore Zirconia. Any s??? My beads are 7 months old and im using ZirkonZahn Colour Liquid Prettau Aquarell Please help..
