Although I have been using them since I started working with emax, I don't like the original emax shade pastes, particularly on monolithic zirconia. They do not apply evenly and I see small particles after firing. I like and use the Empress Universal shade pastes whenever possible. I have also tried the GC Luster paste kit, but I sometimes need to fire emax porcelain on the facial or add to contacts. The two firing programs do not work well together. So I am seeking suggestions from the DLN community on what works well on monolithic zirconia, what works well with emax porcelains on pressed emax copings (internal or external application) and what might also work on shade corrections for PFMs using dsign porcelains. Basically I am seeking a stain kit that works well on everything and all situations! Asking too much? I hope not. I am a small lab (1 person) and don't have disposable funds to buy into multiple systems. Thanks in advance for your suggestions.
