Chainglass

“	Chainglass: A glass formed of silicon chain molecules. Depending on heat treatment and various doping techniques, this glass has a range of properties covering just about every material that has preceded it. Chainglass blades can be as hard as diamond and maintain an edge sharper than that of freshly sheared flint, whist having a tensile strength somewhere above that of chrome steel. Chainglass also lacks the brittleness of its namesake. This substance was the invention of Algin Tenkian, and it made him filthy rich.	„
