Abstract


The study investigated the effects of soaking temperature, time and particle sizes, on hardness and density of soda-lime silicates glass. The Experiment was conducted with the heat-treating temperature range between 500-1400oC and soaking time of 1hour, 2hours and 3hours. One hundred and eighty samples of amber and green glasses were employed. Sixty samples for each mesh size of 120µm, 150µm and 180µm were used in the experiment, which reveals that the optimum particle sizes, and temperature are120µm and 1100oC respectively. Whereas the optimum soaking time of 2 hours produced the greatest yield of hardness with mesh 120µm for both amber and green glass samples. It was observed and deduced that finer particles produced greater hardness than larger particles; probably the finer particles have larger surface areas. The hardness of the melted glass was measured according to the ASTM C (1327-03, 2008). Conclusively soaking temperatures, times and particle sizes have greater effects on the property of hardness and density. Whenever heat treatment was increased there was corresponding increase in hardness with drastic increase in density.
