According to ‘James Stevens Curl amp Susan Wilson’ Authors of The Oxford Dictionary of architecture, “glass is a semi or fully transparent hard, brittle, lustrous material made by igneous fusion of silica usually sand with an alkaline sodium or potassium salt and added ingredients. It appears to have come into use for glazing the windows of grander buildings during the Roman Empire.”
