With Ivoclar's new 14:50 second "Fast Fire" the recommendation is that you use spray glaze.  Now I have been the biggest hater of the spray glaze but I may have to eat my words.  When I was in Australia a few weeks ago, an Ivoclar rep and I got into a discussion about the spray glaze and my dislike for it.  He showed me his technique.  

So I took two crowns and figured, lets give this a shot. One will be done with spray glaze and one will be done with the paint on glaze.

 

The technique:  Give a quick 2 second burst, wait 3-4 seconds, another 2 second burst, wait another 3-4 seconds you want to do this till the entire surface is covered and when it dries, you should have a white frosty appearance.  

  The appearance of the crown with the spray glaze as mentioned should be frosty:     With the paint on glaze, use as thin of a glaze as possible.  Do not do a thick layer as it will appear bubbly and have the orange peel appearance:     The end result- you decide.  For me, I see no appreciable difference in the quality of restorations.  To me they appear to be very similar.     Can you tell which is which?     The spray glaze is slightly better but I don't know if its worth the extra material that you waste.  To me, the end result of both is similar with the spray glaze with a slight advantage.  Bottom line is that if you love the paint on glaze, you can use it in the restorations at the 14:50 cycle without too much worry.
