Cement Glass

• arclein
A fantastic device called an aerodynamic levitator, which uses nozzles pumping out inert gas to levitate a material, is then used to levitate the molten cement. The levitator prevents the molten cement from touching the walls of the container, preventing unwanted crystal formation. Different gases are introduced into the chamber to modify the chemical bonds that formed as the liquid cement cools into a glass.
