Despite being brittle, buried silicate glass will survive for very long periods if not disturbed, and many examples of glass fragments exist glass noodle salad jamie oliver early glass-making cultures.
Archaeological evidence suggests glass-making dates back to at least 3,600 BC in Mesopotamia, Egypt, or Syria. Although the atomic-scale structure of glass shares characteristics of the structure of a supercooled liquid, glass exhibits all the mechanical properties of a solid. What is the nature of the transition between a fluid or regular solid and a glassy phase? The deepest and most interesting unsolved problem in solid state theory is probably the theory of the nature of glass and the glass transition. The tendency for a material to form a glass while quenched is called glass-forming ability.
Glass can form naturally from volcanic magma. Naturally occurring obsidian glass was used by Stone Age societies as it fractures along very sharp edges, making it ideal for cutting tools and weapons. The term glass developed in the late Roman Empire. In post-classical West Africa, Benin was a manufacturer of glass and glass beads. Glass was used extensively in Europe during the Middle Ages.
During the 13th century, the island of Murano, Venice, became a centre for glass making, building on medieval techniques to produce colourful ornamental pieces in large quantities. Throughout the 20th century, new mass production techniques led to widespread availability of glass in much larger amounts, making it practical as a building material and enabling new applications of glass. Glass is in widespread use in optical systems due to its ability to refract, reflect, and transmit light following geometrical optics. Glass transparency results from the absence of grain boundaries which diffusely scatter light in polycrystalline materials. In the manufacturing process, glasses can be poured, formed, extruded and molded into forms ranging from flat sheets to highly intricate shapes. The finished product is brittle and will fracture, unless laminated or tempered to enhance durability.
The density of glass varies with chemical composition with values ranging from 2. The observation that old windows are sometimes found to be thicker at the bottom than at the top is often offered as supporting evidence for the view that glass flows over a timescale of centuries, the assumption being that the glass has exhibited the liquid property of flowing from one shape to another. This assumption is incorrect, as once solidified, glass stops flowing. The rate of glass flow in mediaeval windows was calculated in 2017. It was estimated that the rate of flow would not exceed 1nm per billion years. Fused quartz is a glass made from chemically-pure silica. Aluminosilicate glass tends to be more difficult to melt and shape compared to borosilicate compositions, but has excellent thermal resistance and durability.
