Advancing iznik tiles to the 21st century by applying nano structured materials

摘要

Nanotechnology actually started in the 9th century in Mesopotamia with a lustre layer on ceramic surfaces applied by ceramic artists. Reducing atmosphere lusters are classified into two groups, due to preparation and implementation, as in-glaze and over-glaze lusters. Over-glaze luster is a kind of decoration and in-glaze luster is a kind of glaze. Cooling is achieved in reducing the atmosphere for both types of lusters and the nano particles give the luster effect. Traditional Iznik tiles were produced in iznik from the 14th century to the 17th century. These ceramics are known as "unproducible" due to their high quartz content, composition and unique processing steps. The production of iznik ceramics stopped in 1716 due to unknown reasons with no written documents about their production being left. TUBITAK MRC and the iznik Foundation are carrying out an important experimental project to improve and understand the effects of nanotechnology application in iznik ceramics. In this study, the high quartz content of iznik ceramics is kept as it is and nanotechnology is applied at the decoration stage as nanometer sized pigments and as nanometer sized metallic particles in glazes for a luster effect. A comparison is carried out between traditional and modern iznik ceramics in colour, brightness and other properties by SEM and XRD characterisation techniques.
