Control of thermal breakage in glass
Introduction
A window is an architectural element that is located in an opening or opening. A set of devices used to close that opening is also called a window.
The term comes from the Latin ventus (wind), referring to the ventilation capacity "Ventilation (architecture)") that it provides. Formerly the window was also called fenestra or also called "finistra", identical to what it is called in Latin and Greek. This would be the direct mode of etymological derivation. However, although this name is now out of use, words related to it are preserved, such as defenestrate which means throwing someone out of a window.
The Romans were the first to use glass for windows, a technology that was probably first produced in Roman Egypt "Egypt (Roman province)"), in Alexandria around 100 AD. C. Paper windows were inexpensive and widely used in ancient China, Korea, and Japan. In England, glass became common in ordinary house windows only at the beginning of the 19th century, while windows composed of panels of flattened animal horn were used as early as the 19th century. In the 19th century American West, traveling tribes began using "oiled paper" windows. Modern-style floor-to-ceiling windows became possible only after industrial plate glass manufacturing processes were fully perfected.
History
In the century BC. C., the first windows were unglazed openings in a roof to let in light during the day. Later, windows were covered with animal skins, cloth or wood. Blinds that could be opened and closed would come later. Over time, windows were built to protect inhabitants from the elements and transmit light, using multiple small pieces of translucent material, such as flattened pieces of translucent animal horn, thin sheets of marble (e.g. phengite), or pieces of glass, set in frames of wood, iron or lead. In the Far East, paper was used to fill windows.[1]
The Romans were the first to use glass for windows, a technology that was probably first produced in Roman Egypt. Possibly, cast glass windows began to appear in Alexandria in the year 100 AD. C., although with poor optical properties, but these were small, thick productions, little more than blown glass jars (cylindrical shapes) flattened into sheets with circular striation patterns throughout. It would be more than a millennium before window glass became transparent enough to see clearly, as we now think.
