About ceramic brushes
Ceramic brushes carry the porcelain paste to the work: in the layering technique the powder is mixed with liquid and applied with a brush. One study describes the layering as done by hand by an experienced technician.
A ceramist is one who has proficiency in ceramics, the art of making porcelain dental restorations. In the layering technique porcelain powder is mixed with its liquid and the paste is applied with a brush in several steps.
Porcelain condensation is the step that makes the porcelain denser by removing excess water with vibration and blotting.

Firing is the process of porcelain fusion that produces the restoration.
The glaze is the final firing, in which the surface is vitrified to a high gloss.
