Glass is a very important material that is used in many areas such as tableware, windows, automobile glass in human life and usage areas of glass have been increasing day by day. Glass consumption is also increasing with the increase in human population.
On the other hand, environmental factors have become a threat to people because of population growth. Therefore, adding to antibacterial feature to the materials used frequently in daily life has become important. Some metal ions such as silver, strontium, copper and zinc have the function of struggle bacteria and defuse the proteins of these bacteria. Therefore, it is important to add such ions to the glass to give the antibacterial feature. Glass products with antibacterial properties can be produced by using sol-gel method and chemical tempering. However, these methods require additional process for antibacterial glass production.

Zinc oxide, is an inorganic compound which is soluble in acid and alkaline, but can not dissolve in water and alcohol. It has white powder appearance. Due to its’ unique properties such as high refractive index, high thermal conductivity, antibacterial property, low expansion coefficient, it is widely used in glass industry. Zinc oxide exhibits antibacterial behaviour against bacteria and is a reliable material for human and animal health.

This study is aimed to investigate, produce, and characterize glass materials with enhanced antibacterial property by using classical melting method without additional process. Different glass batches giving compositions that contain zinc oxide were first prepared and then melted to produce antibacterial glass samples. After the melting process, antibacterial, physical and mechanical properties of the obtained glasses were characterized by using different techniques. Overall results showed that glass samples produced by using classical melting method showed antibacterial property at the desired level. It was thought that the produced antibacterial glass samples may be good candidates for commercial purposes.
