Abstract

This research deals with (Production of Volcanic Glaze via welding electrodes waste &applying it to Ceramic Surfaces), which consists of five chapters. The first one includes a presentation of the research problem to find out is it possible to produce a volcanic glaze by using welding electrodes waste and apply it to ceramic surfaces?, while the importance of research in identifying the characteristics of this technique where from the possibility of applying it to the ceramic surfaces which contribute to the demonstration of new techniques in the field of ceramic art, whilst the research aims is possibility to produce the volcanic glaze via welding electrodes waste after that apply it on the ceramic surfaces. The research borderlines include the addition of welding electrodes waste into Alkali-Ready glaze applied onto colored ceramic surfaces at a temperature of (820 °C) to produce of volcanic ceramics. The second chapter contains the theoretical framework, as this chapter reviewed the structure of glass and the color pigments and welding electrodes, through which the color and texture are determined. In addition, the volcanic ceramic from the historical and technical reviewed. The third chapter includes the selection of additives to the glaze mixture based on three color pigments (Red, Yellow, Blue) which are consider the most common color pigments at the potter. Welding electrodes waste was added in three weight ratios (5, 10, 15 %) to the glaze mixture (second layer) with fixing of the weight percentages of whole materials and an incarcerate the variable only in the silicon carbide produced by welding electrodes waste to produce volcanic glaze, whence it has been applied to Italian Alkali-Ready glaze where the number of colored glazed samples are (9). The fourth chapter included the research sample, which has been selected through the variety of silicon carbide ratios which produced from welding electrodes waste and the size of the craters in addition of the surface's texture & color nature. The number of research samples (9) samples representing the research community with achieve the laboratory characteristics. Where the tests of the density and surface tension of the glaze are achieved, and a chromatography analysis has been done by using the system (L.a.b) to find out the numerical values of the color produced, the texture test achieved to understand the nature of the surface. The tests supporting the results of color and texture, the microscopy was achieved onto the research samples, which highlighted the nature of the colored crystals, the phases and the non-molten materials with their effects onto the color results
