Who made the first mirror?
Justus von Liebig
The silvered-glass mirrors found throughout the world today first got their start in Germany almost 200 years ago. In 1835, German chemist Justus von Liebig developed a process for applying a thin layer of metallic silver to one side of a pane of clear glass.
What was the first mirror?
Reflective surfaces made of polished obsidian are the oldest “mirrors” in the archaeological record, dating back as far as 4000 BCE. The first evidence of mirrors as grooming tools dates to the 5th century BCE, in illustrations of elegant Greeks gazing at hand mirrors (these illustrations are found on antique pottery).
How old is the oldest mirror?
The oldest known mirrors date to around 6,000 BC from the site of Çatal Hüyük in modern-day Turkey. Around 3,000 years later the Egyptians made metal mirrors from highly polished copper and bronze, as well as precious metals.
When did mirrors come about?
The mirror as we know it today was invented in 1835. The process of adding a silver nitrate coating to clear glass was created by Justus von Liebig, though today aluminum is frequently used.
How is a mirror made?
The modern mirror is made by silvering, or spraying a thin layer of silver or aluminum onto the back of a sheet of glass. 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].
Who made the mirror and why?
The invention of the silvered-glass mirror is credited to German chemist Justus von Liebig in 1835. His wet deposition process involved the deposition of a thin layer of metallic silver onto glass through the chemical reduction of silver nitrate.
What Colour is a mirror?
As a perfect mirror reflects back all the colours comprising white light, it’s also white. That said, real mirrors aren’t perfect, and their surface atoms give any reflection a very slight green tinge, as the atoms in the glass reflect back green light more strongly than any other colour.

How is glass made?
In a commercial glass plant, sand is mixed with recycled glass, sodium carbonate, and calcium carbonate. These substances are then heated in a furnace. Once in a liquid state, it is poured into molds to shape, or poured on a flat surface to make sheets of glass.

What Colour is water?
blue
While relatively small quantities of water appear to be colorless, pure water has a slight blue color that becomes deeper as the thickness of the observed sample increases. The hue of water is an intrinsic property and is caused by selective absorption and scattering of white light.
What color is a sun?
White

Connecticut Sun/Colors
When we direct solar rays through a prism, we see all the colors of the rainbow come out the other end. That’s to say we see all the colors that are visible to the human eye. “Therefore the sun is white,” because white is made up of all the colors, Baird said.
