Glass is made up of several ingredients but the most important sand or also known as silica as well as soda ash and lime. In the glass making process, glass can virtually be made into any shape and also be given any color. Color is added by adding another ingredient that will give it the color property, for example adding cobalt will give a blue color.

But the outcome of the glass making products gives us wonderful object that we can use to decorate our homes or use for everyday life such as windows, cups, light bulbs and buildings.
