Glazing monolithic emax is all about accepting the fact it's better to glaze twice, learning which tools work best to achieve a good glaze, and lastly, learning how little to dilute your glazing paste. I maybe the first to say this, I actually achieve very high glazes and trying to learn out to gain back that tectured look of layered porcelain ( press/fire in ep 5000) with monolithic emax.. and still learning. GC Lustre Stains helps with the texture, sometimes a bit of a problem matching the shade with their lack of colors. My favorite tool for finishing is my Noritakes Meister wheel. Its the SD-61, large diameter wheel, great to finish surface and around margins, any porcelain, will not chip emax or porcelain. This wheel is comparable to some of the Axis yellow wheels. The grey wheels used on porcelain margins that come in course, med, and fine, work great also, and diamonds. Lightly sandblast before glazing as directed in the emax manual.
If your having problems, smooth off a cental test crown using one tool on the facial, and another on the lingual, and fire using glaze paste, no stain to see the difference. Just takes a little practice and being consistant to achieve high glazes in emax..... No big deal !
