Self-cleaning glass is a specific type of glass with a surface that keeps itself free of dirt and grime.

The first recorded use of glazing in windows was by the Romans in the first century AD. This glass was rudimentary, essentially a blown cylinder that had been flattened out, and was not very transparent.
A very important advance in glass manufacture was the technique of adding lead oxide to the molten glass; this improved the appearance of the glass and made it easier to melt using sea-coal as a furnace fuel. This technique also increased the "working period" of the glass, making it easier to manipulate.
Eureka Tower in Melbourne has a glass cube which projects 3 m (10 ft) out from the building with visitors inside, suspended almost 300 m (984 ft) above the ground. When one enters, the glass is opaque as the cube moves out over the edge of the building. Once fully extended over the edge, the glass becomes clear.
Low-iron glass is a type of high-clarity glass that is made from silica with very low amounts of iron. This low level of iron removes the greenish-blue tint that can be seen especially on larger and thicker sizes of glass. [1] Low-iron glass is used for aquariums, display cases, some windows, and other applications where clarity is desired. [2]
