How is glass made for kids

Sand, lime and soda are heated together in a furnace to make liquid glass. Rollers are used to flatten glass into sheets, which are first cooled then cut. Liquid glass from a furnace is floated and slowly cooled on the surface of liquid tin. After the glass has cooled down, it is cut into pieces. Vases, ornaments and other in-tricate glass objects are made by a glass-blower. The glass-blower uses a metal blowpipe which has a blob of hot glass at the end of it.

A glass blower then blows the soft glass into shape with his hands. Glasses, window panes, mirrors are few of the many things that are made from glass. Glass is not only useful, but can look beautiful too. Windows made of stained glass are works of art.

The myth that glass is actually a liquid comes from the fact that old windows in houses and churches — years old are sometimes a little out of shape: thicker at the bottom than the top. This is actually due to the process of glass making in the past which led to the glass pane being thicker at one edge than the other. It was sensible to install the windows with the thick edge at the bottom.

Sometimes a window can be found with the thick edge at the top of the window.
