Doing a tabletop veneer number 19, shade A1, stump shade N D7. Remember correctly, the guide suggested pressing out of HT BL 1, but I thought it be too bright, so also pressed out of HT A1.
Was able to finish the veneer pressed out of HT BL 1, but both veneers that I pressed out of HT A1 cracked in half after cooling from the glaze cycle. I'd say this is a pretty ideal prep, definitely no sharp edges to deal with. The crack ran buccal to lingual. These two veneers were not touched with a carbide bur at all. None of the veneers had any type of layering done.
So the question is, why didn't the HT BL 1 veneer crack? Or why did the HT A1 veneers crack?
Thanks
