Abstract

This research is mainly about the use of pigments in art glass. Flat plates of glass are used as raw material in art glass especially in multi layer formed by the fusion process.

In this technique the most important factor is the compatibility of glass which has been examined here by producing colorful glasses with different shapes so that they fit each other with no defects. Various stain formulations such as; metal oxides and their salts, complex stain compounds, non oxide pigments and metal colloids are investigated. From these groups some of the ionic pigments which are readily available and been used in ancient art glass with different percentages have been applied and their chromatic properties have been reviewed.

The tables are briefly shown the investigation method. Mainly it is needed to reach colorful glass that could join together in a fusion process and produce fully stable pieces with no defects. Some simple art glass, which has been produced by flat glass and their procedures are presented.

Key words:

Art glass, glass fusion, glass defects, pigments in glass, Ionogenic pigments
