Production of Enamel Stains from Igbokoda Silica Sand

Abstract

Silica sand was sourced from Igbokoda, ondo state, this was washed, dried and the percentage clay and organic matter present in the silica sand determined. Some percentage of the silica sand was used to compose different batches of  enamel compositio and was fired to a temperature of 1200^oC. The compositions were fritted in metallic bucket and then pulverized to form powder. The powder was mix with gum arabic to form a paste and this was used to print on ceramic wares and glass cups. The printed wares were tested to determine the resistance of the wares to acid and base environment. From the test, the result showed that the enamel produced exhibit a good resistance to acid and base.
