Özet

Luster is a thin film layer formed on the glaze surface. This thin film layer is formedwhen the metal

ions in the glaze move towards thesurface in the reduction environment.

In this study, Silver Nitrate (AgNO3) salt was used to create luster on the surface of theglaze.

Leaded and alkaline glaze recipescontaining Silver Nitrate and various metal oxideswere prepared

and applied with the help of a brushon test tablets obtained from chamotte clay andfired at

1000oC. Glazed test tablets were fired in a gas oven at 1000oC. When the oven cooled downto

850oC, the test tablets were taken out of theoven with the help of tongs and subjected toreduction

process.The luster glazes obtained at theend of the reduction process were analyzed byoptical

microscope, SEM, EDS and XRD analysis.

The fired biscuit pieces (chamotte) in the chamotte clay caused the surface to have a rough

structure. It was observed that the lustereffect increased when the glaze was appliedthicker.

In addition to the luster effect, a different artistic effect has also emerged due to thetextured

appearance of the surfaces obtained.
