naked eye or a microscope in order to check if there are any scratches or unevenness. Metal is still used to make some of today`s mirrors which use highly polished stainless steel which will not tarnish. These were highl prized, valuable artifacts of their time. But there are many applications in which stainless steel mirrors are highly suitable, such as traffic mirrors. Acrylic mirrors are lightweight and cheap to manufacture, making them very affordable mirrors. Mirrors have advanced from reflective pools and polished metal surfaces to clear glass handheld and bathroom mirrors. It was also very difficult to achieve a perfectly flat surface, especially on larger metal mirrors. Materials which are commonly used are metal coatings such as silver, gold or chrome. An important part of the manufacturing process is the quality control of mirrors. He developed a process using silver nitrate to deposit a thin, even layer of metallic silver onto a flat plate of glass. The invention of silvered glass mirrors is recorded to have taken place in 1835 by the German chemist Justus von Leibig. The manufacturing process of high quality, semi rigid polycarbonate mirrors is a more costly than for acrylic mirrors, making them more expensive. Mirrors are made by depositing a very thin and smooth layer of silver on a piece of glass. Making a mirror can be done at home with only a few supplies easily acquired at a local chemistry shop. In classical antiquity, solid metal (bronze, later silver) was used to manufacture mirrors and mirrors were too expensive; they were also prone to near-perfect and undistorted reflection. An important attribute required of a mirror is that the surface is perfectly flat so that the reflected image is not distorted. Instead these ancient mirrors were made by blowing glass bubbles and cutting a small circular section to produce either a concave or convex mirror. distortion of the image reflected. Polished Stone Mirrors The earliest examples of man-made mirrors were found in Turkey, dating from around 6,000 BC, created from obsidian, a naturally occurring volcanic glass which can be polished to create a reflective surface. Humans have always taken a keen interest in reflections leading to the development of today`s sophisticated mirrors. Today, the mirror substrate is first shaped, then polished and cleaned, and finally covered. Web Design by Worldwide Webdesign, Bird Free Fire Gel and Bird Deterrent Spikes, Key Management, KeySafes & Security Cabinets, Mirrors - Security Mirrors & Safety Mirrors, Motorcycle and Leisure Equipment Security, Retail Security & Cash Protection Products, Searching Insight-Security Knowledge Base, Insight Security Environmental Responsibilities. thickness of the mirror is very important, with its strength increasing proportionately to its thickness. The kind of coating to be used is specified by the mirror design. But glass has little reflectivity making it necessary to coat glass with a reflective material in order to create a mirror. Gradually, people started to use gold, silver, and aluminum to create mirrors in the similar manner This silvering process led to mass production of affordable mirrors. It was sold for $40. A problem with early metal mirrors was that they would tarnish easily requiring frequent repolishing. They have been used in interior decoration since the 17th century, and reflective surfaces on cars a… How mirrors are made History of Mirrors. I did a Belknap online with an 22" x 33" with an arched top and carved wood edge that was made in 1923. Set new standards for safety mirrors & security mirrors and are available in a choice of grades;   POLYMIR   and   P.A.S. It is very important that the glass is polished to perfection, any dip or impurity left on glass would made waves in the mirror, which would cause Mirror History. (Note: Manufacturers warranty applies to mirror, frame & fixings under normal operating conditions.). Materials which are commonly used are metal coatings such as silver, gold or chrome. These stones when highly polished were able to reflect with a great clarity. Glass is a major mirror component due to its transparency, ease to fabrication, rigidity, hardness, and ability to take a smooth finish but it is not very good material for reflection. So buy now with confidence - and join the thousands of happy customers we have helped over the last 20 years... and remember, if you're not sure what you need, or which solution is best for you, our specialist advisors will be pleased to help. the ability to focus as well as reflect light. Stone mirrors tended to have poorer reflectivity than metal mirrors. scientific research, the surface needs to be designed in particular way to retain uniformity while adding a curvature. Through mirror is painted to prevent damage to the metal coating. The earliest examples of man-made mirrors were found in Turkey, dating from around 6,000 BC, created from obsidian, a naturally occurring volcanic glass which can be polished to create a reflective surface. The addition of a scratch resistant surface helps to prevent scratching. Apparently the company still makes mirrors. even today. Mirrors have to be specially designed in order to become effective, and the glass sheets that are used must be flat and durable. Glass is a major mirror component due While glass is great for optics it has some disadvantages when compared with modern plastic materials. They are therefore a potential hazard in some applications and unsuitable for use in public spaces. they used the obsidian stone. Durability and reflectivity are the They covered the back of the glass with mercury to obtain This layer prevents the light from passing by and reflection takes place and we are able to see ourselves in the mirror. Ancient written accounts indicate that mirrors made from coated glass were made and used in Lebanon from around the first century. Click here to see - Mirror Products Index Page, Co. Reg: 2649410Vat no: GB 587 6549 73Page 1160, Insight Security Mirrors can be classified in many ways; including by shape, support and reflective materials, manufacturing methods, and intended application. For heavy-duty mirrors and mirrors used in times, as civilization evolved, technology did too. As we all know mirrors are used in our day to day life. A method for creating flat sheets of glass was developed in Germany during the middle ages. Glass, chrome and aluminum are the materials commonly used to create typical mirrors. corrosion. Polished stone mirrors have also been found in Central and South America dating from around 2,000 BC. © 2020 - Mirror History | Privacy Policy | Contact. From the earliest recorded history, humans have been fascinated by reflections. Mirrors are made by applying a reflective coating to a glass sheets. most important characteristics in the choice of the coating. Justus Von Leibig invented the process in 1835, but most mirrors are made today by heating aluminum in a vacuum, which then bonds to the cooler glass [source: Britannica ].
