BURNING GLASS Meaning and
Definition
-
A burning glass refers to a convex lens that is specifically designed to concentrate sunlight into a focused beam, ultimately producing a high amount of heat. The lens of a burning glass is typically made of a transparent material, such as glass or quartz, and has a curved surface on both sides. Its shape enables it to converge the light rays towards a central point, commonly known as the focal point.
When the burning glass is accurately aligned with the sun, it harnesses the sun's rays and concentrates them onto a particular spot. This concentrated beam of sunlight generates an intense amount of heat, often generating temperatures capable of igniting flammable materials or burning objects. The exact amount of heat produced depends on various factors, such as the size and curvature of the lens, as well as the atmospheric conditions.
Historically, burning glasses were widely used for various purposes, such as starting fires, kindling torches, or performing scientific experiments that required a high temperature source. In modern times, burning glasses hold more of a novelty value or find applications in niche areas like solar energy research or certain industrial processes. Nevertheless, the term "burning glass" remains an important part of the scientific lexicon, representing a lens-shaped device used to concentrate sunlight into a powerful and focused beam, which can generate intense heat.

Etymology of BURNING GLASS
The word "burning glass" comes from the combination of two words.
The term "burning" is derived from the Old English word "byrnan", which means to be on fire or to burn. It can be traced back to the Proto-Germanic word "brinnan", related to the Old High German "brinnan" and the Old Norse "brenna".
The word "glass" comes from the Old English word "glæs", which refers to a transparent and brittle substance made by melting sand with other ingredients. It has its roots in the Proto-Germanic word "glasam" and can be linked to the Old Norse "gler", the Old Frisian and Dutch "glas", and the German "Glas".
