[The study of color stability of ceramic stains subjected to glazing temperature]
Abstract:
Ceramic stains are used to modify the final colors of ceramic dental restorations. They are not color stable when subjected to glazing temperature. In order to understand the color change characteristics, the study tested the color stability of the five Vita VMK68 stains. The international color standard CIE1976LAB color system and CS-5 Spectrocolorimeter are used. The results indicate: significant color changes are noted for five stains; the color change characteristics among them are different; yellow-brown stain shows the most color unstability after firing.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
