THE EFFECT OF IRON CHLORIDE ON THE CERAMIC SURFACE

Abstract

The purpose of this research is to study the effect of iron chloride on the surface of ceramics, as well as the use of iron chloride to obtain multiple colours, taking advantage of the difference and colour variation resulting from different proportions of iron chloride and saving effort, time and money for the potter to obtain the best chromatic results for glass coloured with iron chloride.The researchers adopted the (experimental approach) because it is an approach based on scientific experience to achieve the goal of the study in an accurate scientific manner. The researchers adopted the method of spraying the solution on the ceramic piece after the exploratory experiments. The researcher reached the best result for obtaining the best pottery body that is resistant to thermal shock and easy to form. The clay was prepared using kaolin (60%), glass sand (20%) and pottery powder by (20%)We concluded that alumina is not the only cause of glass adhesion to the pottery body, but oxides of copper, iron and zinc, which have proven successful in improving the adhesion strength without the need to increase the percentage of alumina. It is possible to use high percentages of additives to obtain special effects in artwork, especially in pottery sculpture. Color effects vary with different temperatures, the amount of additive.
