What porcelain natural layering technique?

Applied to a solid base, each layer of porcelain helps recreate the shape and colour of natural teeth. Explanation:

The layers have to be applied in such a way that, when light strikes them, they match their surrounding dentition*. This is achieved using different layers of porcelain material.

Explanation:

The technique of layering on different colors one over another produces an effect on porcelain signs called shelving. When you look at a porcelain sign from an angle you can see visible ridges along the edges of color where one has been layered over another.
