Default Glass

First of all, glass is made out of sand and it is first melted in a really hot oven. Then people have to shape the glass very quickly before it cools. When glass leaves a hot area it will cool down very quickly and if it cools down to fast it will break. So techically glass needs to stay in a revenalty warm area but not to cold.
