[QUOTE="tandob, post: 326001, member: 22934"] Sometimes when I am layering a buccal cutback on zirconia it pops off the in oven mid-fire due to contraction shrinkage. I do a washbake cycle and always condense and dry the porcelain thoroughly. I've found it happens more often when the buildup is thicker. Does anyone else experience this problem? What are your techniques to mitigate it? Any techniques to reduce firing shrinkage in general? I am working with Vita VM9. Thanks for any ideas T [/QUOTE]
