Abstract

This study included coloring pottery using oxides and colorful pigments added with glass alkali the low temperatures and proportions grains fixed to be the application of stained glass in a manner overlay layers where application is glass the first layer near the body potter using glass alkali with tints of color to be the base of the oxides on the grounds that the oxides colorimetric according ratios are not given added tinted windows fully and allow light to pass through the first layer so it has been applied as a second layer colored oxides.Been using dye orange and violet in the current research are either oxides of iron oxide, chromium, cobalt, manganese, copper and add fixed rates (3%). Application has been using the spray gun and thickness (0.5%) for each layer was burning temperature (920 m). The results of color are confirming the hypothesis that search through the results far relatively results accepted for these oxides and the occurrence of the phenomenon of refraction double layer inside the glass, was conducted chromatography using the system (L .a .b) for the purpose of determining the numerical values ​​of the colors produced as an examination optical microscope to identify the spread of colorings within the layer of glass was the most important results is possible to get multiple color ranges through overlay layers of colored glass. The results of the samples to a different color to what is known and expected for colors according oxides used, was to overlay a clear impact in bringing about the results of the new color, and a single. Possible to produce overlay systems coloring ion and crystal. The use of coloring system crystalline layer first helped change the results of the colorimetric system coloring to tint the second, and using elements of the transition.
