Though the underlying mechanism was not known at the time, the effects of "tempering" glass have been known for centuries. Consequently, annealed glass is fragile and breaks into irregular and sharp pieces. The most commonly used glass - like, up to 90% of all glass made - is Soda-lime glass, the least expensive form of glass. [13] The first patent on a whole process to make tempered glass was held by chemist Rudolph A. Seiden who was born in 1900 in Austria and emigrated to the United States in 1935.[14]. Tempered glass didn’t exist in Mohs’ time (early 19th century), so it didn’t make it to the chart back then — but that was changed as soon as the tempered glass … Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempered glass is also used in the home. Tempered glass is sometimes known as Bastie glass after de la Bastie. 2. The granular chunks are less likely to cause injury. Using tempered glass can pose a security risk in some situations because of the tendency of the glass to shatter completely upon hard impact rather than leaving shards in the window frame. So happy to know that tempered glass is very important. Tempered glass is made by heating and cooling a piece of standard glass in a tempering furnace. It is forced to cool rapidly, which additionally increases the breaking point. In 1877 the German Friedrich Siemens developed a different process, sometimes called compressed glass or Siemens glass, producing a tempered glass stronger than the Bastie process by pressing the glass in cool molds. Now if there was only a way to make sure that there wasn’t a mess when it shattered. They are made with Japanese glass, 5 layers of security and the most advanced technology worldwide.
