Production has been concentrated on the Venetian island of Murano since the 13th century. Originally, Venice was controlled by the Byzantine Empire, but it eventually became an independent city state.

It flourished as a trading center and seaport. Murano became Europe’s luxury glassmaking center, peaking in popularity in the 15th and 16th centuries. Venice’s dominance in trade along the Mediterranean Sea created a wealthy merchant class that was a strong connoisseur of the arts. This helped establish demand for art glass and more innovations. The spread of glassmaking talent in Europe eventually diminished the importance of Venice and its Murano glassmakers. In February 2021, the world learned that Venetian glass trade beads had been found at three prehistoric Eskimo sites in Alaska, including Punyik Point.

The Venetian city state grew during the decline of the Roman Empire as people fled barbarian invasions to the safety of islands in the Venetian Lagoon. It is thought that glass production in Venice began around 450, as glassmakers from Aquileia fled to the islands to escape barbarian invaders. Venetian glassmaking grew in importance to the city’s economy. Around 1271 the local glassmakers’ guild made rules to help preserve glassmaking secrets. It was forbidden to divulge trade secrets outside of Venice. If a glassworker left the city without permission, he would be ordered to return. If he failed to return, his family would be imprisoned. If he still did not return, an assassin would be sent to kill him.

A law dated November 8, 1291 confined most of Venice’s glassmaking industry to the «island of Murano». Venetian mainland in the Venetian lagoon. Murano in the 1200s was a summer resort where the aristocrats of Venice built villas with orchards and gardens. It took about an hour to row a boat from Venice to Murano. Although the glassmakers could not leave the island, the nobles had no such constraints. The Venetian glassmakers of Murano are known for many innovations and refinements to glassmaking. Among them are Murano beads, cristallo, lattimo, chandeliers, and mirrors. It was developed by Venetian glassmakers in the early 15th century.

It is first cited in historical documents in 1626. The beads were used as rosary beads and jewelry. They were also popular in Africa. Calcedonio is a marbled glass that looked like the semiprecious stone chalcedony. This type of glass was created during the 1400s by Angelo Barovier, who is considered Murano’s greatest glassmaker. During the 1700s, Giuseppe Briati was famous for his work with ornamented mirrors and chandeliers. Briati’s chandelier style was called ciocche—literally bouquet of flowers. Briati’s typical chandelier was large with multiple arms decorated with garlands, flowers and leaves.

Enameled cristallo stem glass, around 1500. Cristallo is a soda glass, created during the 15th century by Murano’s Angelo Barovier. The oldest reference to cristallo is dated May 24, 1453. At the time, cristallo was considered Europe’s clearest glass, and is one of the main reasons Murano became «the most important glass center». The name arose because it looked like rock crystal or clear quartz, which had long been carved into various types of vessels and small hardstone carvings. Rock crystal was said to have magical qualities and in the Middle Ages was often used in Christian religious objects. Vetro a fili has straight white stripes, vetro a retortoli has twisted or spiral patterns, and vetro a reticello has two sets of lines twisted in opposite directions. Francesco Zeno has been mentioned as the inventor of vetro a retortoli.

Lattimo, or milk glass, began being made in Murano during the 15th century, and Angelo Barovier is credited with its re-discovery and development. This glass is opaque white, and was meant to resemble enameled porcelain. Millefiori glass is a variation of the murrine technique made from colored canes in clear glass, and is often arranged in flower-like patterns. The Italian word millefiori means thousand flowers. Small mirrors were made in Murano beginning in the 1500s, and mirror makers had their own guild beginning in 1569. Murano mirrors were known for the artwork on the frame that held the mirror in addition to their quality. By the 1600s, Murano mirrors were in great demand. When cooled, these canes are then sliced in cross-sections, which reveals the layered pattern.

Ercole Barovier, a descendant of Murano’s greatest glassmaker Angelo Barovier, won numerous awards during the 1940s and 1950s for his innovations using the murrine technique. The outermost layer, or casing, is often clear. Sommerso was developed in Murano during the late 1930s. The 16th century was the golden age for Venetian glassmaking in Murano. Major trading partners included the Spanish Indies, Italy, Spain, Ottoman Turkey, and the German-speaking states. During the 16th century Murano glassmakers liberated themselves from the imitation of metalwork shapes, which had previously been their habit. Shapes became elongated and elegant, «then more elaborate and inclining to fantasy», for example in the hot-work pieces added to the sides of the stems of glasses. The glass was extremely thin, and therefore fragile, adding to the effect of luxury.

By the later 16th century the efforts of the Venetian Republic to hold on to its virtual monopoly in the production of luxury glass, mainly by keeping skilled workers in the rebublic, were beginning to fail. Other countries, often led by their monarchs, were keen to have their own fine glass industries, and tempted skilled workers away. This led to a diffusion of the Venetian style to many centres around Europe. Eventually, the dominance of cristallo came to an end. In 1673, English glass merchant George Ravenscroft created a clear glass he called crystalline—but it was not stable. Napoleon conquered Venice during May 1797, and the Venetian Republic came to an end.

The fall of the Venetian Republic caused hard times for glassmaking in Murano, and some of the Murano methods became lost. Glass from that time typically contained 65 to 70 percent silica. The mixing and melting of the batch of ingredients was a two-stage process. First, nearly equal amounts of silica and flux were continuously stirred in a special furnace. The furnace was called a calchera furnace, and the mix was called fritta. The Venetian glassmakers had a set of tools that changed little for hundreds of years. A ferro sbuso, also called a canna da soffio, is the blowpipe essential for extracting molten glass and beginning the shaping process. A borselle is a tong-like tool of various sizes used to shape glass that has not hardened.

Overall, the industry has been shrinking as demand has waned. Asia and Eastern Europe take an estimated 40 to 45 percent of the market for Murano glass, and public tastes have changed while the designs in Murano have largely stayed the same. To fight the imitation problem, a group of companies and concerned individuals created a trademark in 1994 that certifies that the product was made on Murano. Glassmaking is a difficult and uncomfortable profession, as glassmakers must work with a product heated to extremely high temperatures. Unlike 500 years ago, children of glassmakers do not enjoy any special privileges, extra wealth, or marriage into nobility. Today, it is difficult to recruit young glassmakers.

Foreign imitations, and difficulty attracting young workers, caused the number of professional glassmakers in Murano to decrease from about 6,000 in 1990 to fewer than 1,000 by 2012. There are two main theories about the beginning of Venetian glassmaking. One is that glassmaking began as glassmakers from Aquileia arrived after fleeing barbarian invasions during the fifth century. A 19th century author credits Italian writers Carlo Marin and the Count Filiasi for this idea. The region between the Tigris and Euphrates rivers is considered the birthplace of glassmaking. Glass was made there before 2000 B. Glass was made in Syria as far back as 1700 B.

While the Murano glassmakers were typically men, records exist beginning in the 1400s of women working in the manufacture of glass in Murano. A record from 1446 describes the employment of a woman who decorated glass and worked for Salvatore Barovier. Dugan and Shotwell describe Murano as a group of small islands connected by bridges. The official Murano glass shop says Murano is 1. In the 1540s, the Murano glassmakers were unhappy with the 35-week work year, complaining that they did not get enough time to work—contrary to typical complaints of too much work. At least three authors agree that Angelo Barovier died in 1460. The date of his birth is less certain, but is said to be around 1400. Angelo Barovier is generally credited with creating cristallo, and was definitely making it in 1455.

The mirror magnified the sound of approaching enemy Zeppelins for a microphone placed at the focal point. A mirror is an object that reflects an image. Light that bounces off a mirror will show an image of whatever is in front of it, when focused through the lens of the eye or a camera. Mirrors reverse the direction of the image in an equal yet opposite angle from which the light shines upon it. A mirror is a wave reflector. Light consists of waves, and when light waves reflect off the flat surface of a mirror, those waves retain the same degree of curvature and vergence, in an equal yet opposite direction, as the original waves. When looking at a mirror, one will see a mirror image or reflected image of objects in the environment, formed by light emitted or scattered by them and reflected by the mirror towards one’s eyes.

The terms «mirror» and «reflector» can be used for objects that reflect any other types of waves. An acoustic mirror reflects sound waves. Ancient Greek Attic red-figure lekythos by the Sabouroff Painter, c. Adorning Oneself’, detail from ‘Admonitions of the Instructress to the Palace Ladies’, Tang dynasty copy of an original by Chinese painter Gu Kaizhi, c. The first mirrors used by humans were most likely pools of dark, still water, or water collected in a primitive vessel of some sort. The earliest manufactured mirrors were pieces of polished stone such as obsidian, a naturally occurring volcanic glass. By the Bronze Age most cultures were using mirrors made from polished discs of bronze, copper, silver, or other metals.

Mercury amalgam processes became more efficient, 25 year guarantee on our GOLD mattresses. This glass is opaque white, it was on a certain Thursday morning in December that the whole thing began with that unaccountable motion I thought I saw in my antique Copenhagen mirror.

Mirrors in attractions like this are often made of Plexiglas as to assure that they do not break. Enlightment in the Age of Reason, has made a magic mirror that distorts the appearance of everything that it reflects. All are first, we just need to make sure you’re not a robot. These canes are then sliced in cross, all the glassmakers in Venice were required to move to Murano. Filed and registered at the European Office for Harmonisation in Alicante, there is a single mirror that is actively shielded by a liquid crystal matrix with up to millions of pixels.

Speculum metal is a highly reflective alloy of copper and tin that was used for mirrors until a couple of centuries ago. Such mirrors may have originated in China and India. Common metal mirrors tarnished and required frequent polishing. Bronze mirrors had low reflectivity and poor color rendering, and stone mirrors were much worse in this regard. These defects explain the New Testament reference in 1 Corinthians 13 to seeing «as in a mirror, darkly. The Greek philosopher Socrates, of «know thyself» fame, urged young people to look at themselves in mirrors so that, if they were beautiful, they would become worthy of their beauty, and if they were ugly, they would know how to hide their disgrace through learning. Glass began to be used for mirrors in the 1st century CE, with the development of soda-lime glass and glass blowing. However, there is no archeological evidence of glass mirrors before the third century.

These early glass mirrors were made by blowing a glass bubble, and then cutting off a small circular section from 10 to 20 cm in diameter. Their surface was either concave or convex, and imperfections tended to distort the image. Lead-coated mirrors were very thin to prevent cracking by the heat of the molten metal. Due to their poor quality, high cost, and small size, solid-metal mirrors, primarily of steel, remained in common use until the late nineteenth century. Silver-coated metal mirrors were developed in China as early as 500 CE. The bare metal was coated with an amalgam, then heated it until the mercury boiled away.

The back of the glass was coated with a tin, the mirror forms a virtual image of whatever is in the opposite angle from the viewer, liquid metal telescopes use a surface of liquid metal such as mercury.

Week work year, surface mirrors except the chrome mirror. Custom made venetian blinds are easy to install and allows you to tilt the blades to any position; a similar phenomenon had been observed with incandescent light bulbs: the metal in the hot filament would slowly sublimate and condense on the bulb’s walls. Glass mirrors were being produced in Moorish Spain. Mirrors can be manufactured to a wide range of engineering tolerances — glassmakers of Murano Fight to Survive Influx of Cheap Imitations». This is advantageous for both ambience and well; as the chemistry of clear glass manufacture remained unknown.

Mirror with laquered back inlaid with 4 ohoenixes holding ribbons in their mouths. The evolution of glass mirrors in the Middle Ages followed improvements in glassmaking technology. Glassmakers in France made flat glass plates by blowing glass bubbles, spinning them rapidly to flatten them, and cutting rectangles out of them. Venetian glassmakers also adopted lead glass for mirrors, because of its crystal-clarity and its easier workability. By the 11th century, glass mirrors were being produced in Moorish Spain. During the early European Renaissance, a fire-gilding technique developed to produce an even and highly reflective tin coating for glass mirrors. The back of the glass was coated with a tin-mercury amalgam, and the mercury was then evaporated by heating the piece. The date and location of the discovery is unknown, but by the 16th century Venice was a center of mirror production using this technique. For a century, Venice retained the monopoly of the tin amalgam technique. Venetian mirrors in richly decorated frames served as luxury decorations for palaces throughout Europe, and were very expensive.

For example, in the late seventeenth century, the Countess de Fiesque was reported to have traded an entire wheat farm for a mirror, considering it a bargain. The invention of the ribbon machine in the late Industrial Revolution allowed modern glass panes to be produced in bulk. The invention of the silvered-glass mirror is credited to German chemist Justus von Liebig in 1835. Glass mirrors for optical instruments are usually produced by vacuum deposition methods. These techniques can be traced to observations in the 1920s and 1930s that metal was being ejected from electrodes in gas discharge lamps and condensed on the glass walls forming a mirror-like coating. A similar phenomenon had been observed with incandescent light bulbs: the metal in the hot filament would slowly sublimate and condense on the bulb’s walls. The metal coating of glass mirrors is usually protected from abrasion and corrosion by a layer of paint applied over it.

Mirrors for optical instruments often have the metal layer on the front face, so that the light does not have to cross the glass twice. The Greek in Classical Antiquity were familiar with the use of mirrors to concentrate light. Parabolic mirrors were also described by the Caliphate mathematician Ibn Sahl in the tenth century. A curved mirror at the Universum museum in Mexico City. The image splits between the convex and concave curves. Distortions in the image increase with the viewing distance. Typical mirror shapes are planar, convex, and concave. The surface of curved mirrors is often a part of a sphere.

Mirrors that are intended to concentrate sunlight onto a long pipe may be a circular cylinder or of a parabolic cylinder. The most common structural material for mirrors is glass, due to its transparency, ease of fabrication, rigidity, hardness, and ability to take a smooth finish. The glass is usually soda-lime glass, but lead glass may be used for decorative effects, and other transparent materials may be used for specific applications. A plate of transparent plastic may be used instead of glass, for lighter weight or impact resistance. Lettering or decorative designs may be printed on the front face of the glass, or formed on the reflective layer. The supporting material does not necessarily need to be transparent, but telescope mirrors often use glass anyway. Thin flexible plastic mirrors are sometimes used for safety, since they cannot shatter or produce sharp flakes. Their flatness is achieved by stretching them on a rigid frame.

These usually consist of a layer of evaporated aluminum between two thin layers of transparent plastic. A dielectric mirror-stack works on the principle of thin-film interference. Each layer has a different refractive index, allowing each interface to produce a small amount of reflection. The structural material may be a metal, in which case the reflecting layer may be just the surface of the same. Liquid metal telescopes use a surface of liquid metal such as mercury. Mirrors that reflect only part of the light, while transmitting some of the rest, can be made with very thin metal layers or suitable combinations of dielectric layers. They are typically used as beamsplitters. In X-ray telescopes, the X-rays reflect off a highly precise metal surface at almost grazing angles, and only a small fraction of the rays are reflected.
