Glass
In Glass we have the privilage of working with a material in the transition from a liquid to a solid. We can manipulate it with tools, gravity and our hands. The simple aplication of water to news papper lets us use our hands to form it.
The tools used in the manipulationm of glass are basicly the same as they have been for over two thousand years. Thats when the last great inovation in tools took place with the invention of the blow pipe. Prior to that the glass was formed of a core, and then tne core was removed. This process toook so long that the products were so expensive that only royalty could aford it. With the introduction of the blow pipe, the cost droped to the point that many more people could afford it, and the designs could be more varied. Since then the only real improvements have been in the areas of Energy for the melting of the glass, and the chemistry of the colours and material..
