Various Effects of Silver Mirrors Hiromi Fujiki
Overview… • History of the Mirror • How mirrors are made.. • How mirrors work.. • Use of the Mirror
History of the Mirror • Metallic mirrors in Ancient Egypt -made by gold, silver, bronze etc.. • Basic glass mirrors in the 1300’s -Venice • Production of large size wall mirrors.. -France during the Baroque Period
Metallic mirrors in Ancient Egypt • the third millennium B.C • Polished ->reflective surface of Gold • Later, mirrors made by bronze
History of the Mirror • Metallic mirrors in Ancient Egypt -made by gold, silver, bronze etc.. • Basic glass mirrors in the 1300’s -Venice • Production of large size wall mirrors.. -France during the Baroque Period
Basic glass mirrors in the 1300’s • The first way.. -a mixture of mercury and tin on the back of the glass.
History of the Mirror • Metallic mirrors in Ancient Egypt -made by gold, silver, bronze etc.. • Basic glass mirrors in the 1300’s -Venice • Production of large size wall mirrors.. -France during the Baroque Period
Production of large size wall mirrors • The second half of 17th C -Baroque Period • The Versailles -Hall of Mirrors -Louis XIV • Introduction of Silver Nitrate
How mirrors are made… • Float Glass -a much greater quality! ->very important to make good mirrors • Wash by deionised water & cerium oxide • Spray a thin layer of tin -promote the adhesion of the silver • Silvering, Coppering, Coating…
Red ox Reaction • R -> Reducing agent • Ox -> Oxidizing agent • Mn+ -> Ionized metal
How mirrors work.. • Smooth surface of silver -Doesn’t absorb the light or -doesn’t scatter the light ->Reflect the light perfectly
Human eyes.. • “Everything that can be seen is seen only when light from that object travels to our eyes.” • Object distance = Image distance • law of reflection
Human eyes… • In order to see the image of an object in a mirror, you must sight at the image; when you sight at the image, light will come to your eye along that line of sight.
Human eyes… • the orientation of the image ->left-right reversal
Use of the Mirror • To observe figures • To make space look wider.. • To make rooms brighter…
