When was the convex mirror invented?
The convex glass mirror was a Venetian invention of about 1300, possibly connected with the development of the glass lenses used in the earliest spectacles (invented in the 1280s). By the late fourteenth century, you could find such mirrors in northern Europe.

Who first invented mirrors?
Justus von Liebig

Who invented spherical mirror?
The invention of the silvered-glass mirror is credited to German chemist Justus von Liebig in 1835. His process involved the deposition of a thin layer of metallic silver onto glass through the chemical reduction of silver nitrate.

When was the invention of the glass mirror?
Glass mirrors were first produced during the third century A.D., and were quite common in Egypt, Gaul, Germany and Asia. The invention of glassblowing method during the 14th century led to the discovery of convex mirrors, which increased the popularity of glass mirrors… The history of mirrors starts in the 6000 BC.
How did Justus von Liebig invent the mirror?
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. This technique was soon adapted and improved upon, allowing for the mass production of mirrors.
How did the Phoenicians make the first mirror?
To make a mirror, pre-Christian Lebanese or Phoenicians blew a thin sphere of molten glass into a bubble, and then poured hot lead into the bulb of glass. The lead coated the inside of the glass. When the glass cooled, it was broken and cut into convex pieces of mirror.
