The oldest finds of glass (10,000 years BC) were made in Egypt. Since that time glassware, drinking glasses and bottles have been produced from the basic components of quartz sand, soda and limestone. Glass is transparent, resistant to acid chemical agents and has a high density; it is therefore the ideal material for flasks, pipettes and containers in chemical laboratories.
