    Effect of Silver Oxide on Colour Variation and Gloss of an Opaque Glaze
    (I N S I O Scientific Books and Periodicals, 2014) Israil L.I.; Köseoglu K.; Cengizler H.
    The most important point of whitening frit glazes is the elimination of transperancy. For that purpose, opacifiers are used. In this work, the effect of Ag2O additive on colour variation and gloss of a white opaque glaze, used commonly in ceramic ware production, were investigated at the temperatures of 1040°, 1090° and 1140°C. It was found that colour and gloss of an opaque glaze did not vary significantly with Ag2O addition. Furthermore, Ag2O addition was found to be a viable alternative for reducing the sintering temperature of opaque glaze from 1090° to 1040°C. © 2014 © 2014 The Indian Ceramic Society.

    Tannery wastewater sediments produced by clinoptiolite/polyacrylamide-aided flocculation as a clay additive in brick making
    (Springer International Publishing, 2017) Köseoglu K.; Cengizler H.; Israil L.I.; Polat H.
    Toxic tannery wastewater(s) (TWW) pose(s) a great risk to the environment. This study explores the potential of mitigating the harmful effects of TWW through sedimentation using clinoptiolite in the presence of various anionic, cationic and non-ionic flocculants with different molecular weights and charge densities followed by encapsulation in a brick structure for stability. Compressive strength (CS), size reduction after firing (SRAF), water absorption (WA) and colouring parameters of bricks were determined. X-Ray diffraction (XRD) and scanning electron microscopy (SEM)-energy dispersive X-ray (EDX) analyses were conducted on brick bodies. Kinetic leaching experiments were conducted for possible heavy metal release from the bricks. Bricks containing 10 wt% leather waste and 5 wt% clinoptiolite sintered at 800 °C instead of 920 °C possessed similar properties to the standard brick (SB). © 2017 Australian Ceramic Society.
