[QUOTE="Sda36, post: 326007, member: 17701"] Hi, try and slow your heat rate climb, not sure where you're at with that but 25° C per minute is a good start. Predry 6 min at least, I also use a soak time of 1 min prior to heat rise. This is in case you use any internal stain medium of any sort in your build up technique. Zirconia is an Insulator, not a conductor as with PFM, it requires time and temperatures to respect that. Hope this helps, run a few test firings on sintered chips or un-used crowns to see if this helps you. You can also lightly blast your wash bake to remove any sheen to help wetting the surface and reduce asccotiated surface tension. Can't hurt. Best of luck. [/QUOTE]
