mixed GC Luster Paste with other stain Paul, I now use Lustre on all monolithic emax........Do you remember if you used the neutral , then stains, just like emax stains? I've found that Lustre gives me a layered look and easy to get a glaze. (I usually press with the correct shade, or one shade lighter) maybe that is why I'm not getting a patchy appearance?
Tried GC Lustre on a full contoured bridge zirconia this week, and I couldn't get the shade right.The kit needs more colors to achieve the shades.... Will try the Shofu Art stains next time.
Just for the record, full contour zirconia stained with Vita Akzent stains looks great...
Hi Charles, I have problem with patchy appearance when I am a hurry. Paul and you help me recall of what I have tried to overcome my past experience. I think a thin/dry stain of Universal stain or Vita Akzent won't change the appearance of monolithic Emax or Zircon so this is what did: Mixed them, because GC luster paste did not have varieties stain to cover all 3D shades.
I fire glazing twice on Zirconia or Lava, but once fire on Emax.
To avoid patchy, I mixed either very little of Vita Akzent or Universal stain on a clean pallet with GC glaze liquid to match the Rx shade required. With the hard-to-match shade, I stain on shade guide to verify under magnified scope.
I fire first glaze then correct with second glaze if it is needed.
If the shade was achieved after first glaze, I apply GC Neutral on facial or buccal, and add just enough blue paste irregularly on tip of the cusps to imitate incisal.
Experience the paste thickness when mixing GC paste and using porcelain build up technique also help avoid patchy.
Please give your opinions if my technique incorrect or may cause more problems.
thanks
