The first eyeglasses were estimated to have been made in Northern Italy, most likely in Pisa, by about 1290: In a sermon delivered on 23 February 1306, the Dominican friar Giordano da Pisa (c. 1255–1311) wrote “It is not yet twenty years since there was found the art of making eyeglasses, which make for good vision…

Glass is also considered a good material for mirrors because it can be molded into various shapes for specialty mirrors. Glass sheets are made from silica, which can be mined or refined from sand. The silica, or quartz, is melted to high temperatures, and poured or rolled out into sheets.

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.

A mirror is typically made of glass with a flat or curvy surface, and has a reflective covering over it. Mirrors aren’t only for appearance; they are also used in many technological and scientific components.

Today’s mirrors are also glass, but with a thin backing of silver or aluminum. Chlorine chemistry, in the form of the compound stannous chloride, plays a role in manufacturing mirrors during the process known as “silvering.” Stannous chloride, SnCl2, is a chemical compound of tin (Sn) and chlorine (Cl).

The Mirror Universe is a parallel universe in which the plots of several Star Trek television episodes take place. It resembles the fictional universe in which the Star Trek television series takes place, but is separate from the main universe.

MIRROR: Includes feldspar, silica and silver.

Mineral resources are essential to our modern industrial society and they are used everywhere. We need minerals to make cars, computers, appliances, concrete roads, houses, tractors, fertilizer, electrical transmission lines, and jewelry.

The main parts of every bathroom – the sink, toilet and tub, are made of porcelain. Porcelain is a hard and shiny type of ceramic, or pottery, that is made from the clay mineral, kaolin, and the minerals feldspar and quartz.

Mirrors reflect our world, but by nature their contents aren’t real. Between centuries of superstition, the inherent creepiness of doppelgangers, and the brain’s tendency to go haywire when you look into a mirror too long, it’s a wonder mirrors aren’t more unsettling.

Supernatural Fears Mirrors have long been linked to religious rituals, customs, and superstitions. Some believe that a mirror reflects a person’s soul. In some cultures, individuals cover the mirrors in a newly deceased person’s home to avoid trapping their soul.

A mirror is an opaque object which does not allow light passes through it. The light cannot pass through the mirror from one side to the other side. This doesn’t mean that the mirror is a transparent object. Remember a mirror is actually a thin glass slab with its one side coated with opaque material.

Hey friend , as your question the answer is – Mirror is not a transparent object because it reflects the light which comes towards it and then we can see our reflection in the mirrors. It is an opaque object. Thus mirror is opaque but glass is transparent.

Materials like air, water, and clear glass are called transparent. When light encounters transparent materials, almost all of it passes directly through them. Glass, for example, is transparent to all visible light. Translucent objects allow some light to travel through them.

Examples of transparent items are glass, water, and air. Those materials that allow some light to pass through them are called translucent and include things like frosted glass and wax paper.
