A Study of the Optical Properties of the Local Glass and Compared with the Imported Glass in Iraq

Abstract

Several samples were selected from local and imported glass (Iranian, Malaysian and Chinese) available in the Iraqi market. The light intensity was measured with the change in the thickness to find optical characteristics (reflectivity, refractive index, transmittance, and absorbance). It has been found that the soda-lime-glass, which contain a large amount of silica in its composition, having less amount absorption compared with the imported kinds. The refractive index is independent of the thickness of the glass plates .The Iraqi glass has high reflectance compared for example with the chinese glass.
