Utilization of rice husk fly ash in the color glass production

In this research work, the glasses were prepared by rice husk ash from Yasothon Province, Thailand. The result shows that, after sintered at 1,000 °C (RHA sample), rice husk ash can be used in colorless and color glass production. The color glass can be prepared from RHA and showed light blue (CuO doped), brown (MnO2 doped), deep blue (CoO doped), pink (Er2O3 doped) and green (Cr2O3 doped) color. The color of glasses was confirmed by UV-Visible spectrophotometer. This research is useful in the development of glass from ash and increased utilization of industrial waste.
