This shows a microscopic view of a Cefiontect ceramic. The bottom layer forms the base layer. It is about 300 μm high. Above the base layer is a layer of conventional glaze. It is about twice as high as the base layer. The surface of the conventional glaze is rough and has many height differences. The Cefiontect glaze forms the top layer. It is about half the height of the base layer. The Cefiontect glaze sits on the rough surface of the conventional glaze and ensures that the irregularities are evened out. This makes the surface completely smooth.
