I've been working at this on and off for weeks now. We are finally getting to the end of our Weiland Zeno porcelain supply and forced to switch.
First thing is I am using a Whipmix Pro 200 furnace. I would like to try to make it work if possible. If it won't, can anyone explain what the Ivoclar furnace does differently from a whipmix?
I have read this thread over and over and tried all of it:

Although my situation is different. I am getting trapped gases in the porcelain. I've tried every possible combination of lower the entry temp, where the vacuum starts, making sure the unit is getting heated enough, single stage, 2 stage.. yada yada yada........ I've got it to the point where the porcelain appears to be clear glass, but you can feel it on the surface, then you check under scopes and you can see it. I've attached a photo taken with the macro lens on an iphone.. best i could do.
Is there anyone out there using emax on zirconia with a whipmix furnace and having success?
Any other thoughts? i just cannot seem to get rid of the trapped gases. i have about 3 different dentin bake programs that i've been modifying to try to get something to work and cannot. I also have 2 other whipmix furnaces I have tried and get the same results. Also note, the pro200 has never had metal in it ever. It is a ceramic only furnace.
Argen is our zirconia supplier, but that shouldn't be a factor.
I am using Ivoclar allround model liquid, have tried distilled, have tried 3 other bottles i have here but no difference.
I am using zirliner with their model liquid and following the ivoclar steps.
I have been in touch with various Ivoclar people and not really getting anywhere.
Any ideas would be appreciated. Thanks!
