glass is a translucent or transparent hard object that will break or crack if it is dropped and is often seen being used for windows or glass cups. Annealed glass in particular is made by heating sand and the product of that is then floated upon a pool of molten tin and will then pass through a furnace which controls the cooling temperature of the glass. Another way to make a different type of glass is glass blowing. Glass blowing involves wrapping molten glass around an open ended pipe, someone will then blow into the pole while it is being slowly turned this makes the glass at the other end of the pipe to blow up like a balloon this is often how unusual shaped glass shapes to be created.
