Gold Luster
•
0 likes•954 views
Gold luster is a metallic film that can be produced on glazed ceramics and glass by combining silver and copper compounds and firing the object. It was first developed in the 800s by Egyptian and Syrian glassmakers and later used by Iranian potters in the 13th century to produce shiny, gold-like effects. While gold luster was popular throughout the Islamic world, it is now rare and difficult to produce safely due to its toxic ingredients and hazardous application and firing process.

Objects In Islamic Art - Techniques of Early Islamic Art
The document summarizes various techniques and objects in early Islamic art, including rock-cut crystals, cut and engraved glass, millefiori beads, stained glass, etched glass, and cast glass. It also discusses tools used like the blowpipe and molds. Rock-cut crystals were carved from a single block of crystal by Fatimid artisans. Cut and engraved glass involved both complex relief patterns and fine incisions. The millefiori technique used "thousand flowers" mosaic beads and was developed in Mesopotamia. Stained glass incorporated painted and colored glass in mosaics. Etched glass involved artistic etching of designs on glass surfaces. Cast glass was made using lost-wax casting
GLASS
Glass is a non-crystalline solid that is often transparent and has many uses. The document discusses the history, composition, manufacturing process, types and uses of glass. It notes that the first true glass was made in Syria, and over time glass-making became popular in Egypt and was later used for stained glass and other purposes in buildings. The main components of glass are silica, sodium oxide, calcium oxide and aluminum oxide. Glass can be colored through the addition of metal ions and comes in types like fused glass, borosilicate glass, soda-lime glass and lead crystal glass.
Glass types
Glass is a supercooled liquid that is transparent and unaffected by chemicals. It is most commonly made from mixtures of silica (sand), soda ash, and limestone. The manufacturing process involves mixing these ingredients and heating them to very high temperatures in a furnace until they melt and form a clear jelly-like substance. As this cools and solidifies, glass is formed. There are several types of glass that vary in properties and uses, such as soda-lime glass commonly used for windows and bottles, colored glass, plate glass, safety glass, laminated glass, optical glass, pyrex glass, photochromic glass, and lead crystal glass.

Text daguerreotypes
Daguerreotypes were one of the earliest photographic processes, invented in 1839 by Louis Daguerre. The French government purchased the formula and made it freely available to the public. Daguerreotype studios soon opened across Europe and America, attracting customers from all walks of life who wanted portraits made. However, producing daguerreotypes was a labor intensive and technical process requiring specialized equipment and skills to polish, sensitize, expose, develop and finish the silver-plated copper plates. By the mid-1850s, it was estimated that over three million daguerreotypes were produced annually in the United States alone, representing a major retail industry.
Ceramics
Ceramics are inorganic, non-metallic solids formed through heating and cooling processes. Early ceramics were made from clay but now include a wide variety of domestic, industrial, and artistic products. Ceramic materials are divided into three main categories: clay products like tiles, refractories used in high-temperature applications, and glass. Tiles are commonly used for floors, walls, and roofs and are made from clay due to their durability, variety of colors, and resistance to weathering.
Glass
Glass is an amorphous solid that is formed when a liquid melt cools too quickly to form a crystal structure. It is made primarily of silica along with other ingredients like soda ash and limestone. Glass has properties of both solids and liquids in that it is rigid but its molecules are randomly arranged like a liquid. The history of glass dates back to ancient times when it was discovered during copper smelting and was initially used for jewelry. While the chemical composition of glass has not changed much, modern production methods have advanced significantly from ancient techniques.
Chemistry
Glass and ceramics are both made from sand but have different properties. Glass is made by heating sand and cooling it rapidly, resulting in an amorphous solid structure. The most common type of glass is soda-lime glass, made by heating sand, limestone, and sodium carbonate. Adding boron oxide forms borosilicate glass, which is more heat resistant. Lead crystal glass contains lead and is used for fine glassware. Ceramics are made from clay like kaolin, which hardens permanently when heated. Ceramics are very hard, brittle, chemically inert, and resist compression, making them suitable for uses like pottery, tiles, and electrical insulators.
Phoenician Glass Making
The Phoenicians discovered glass accidentally when sailors melted natrum (soda) and sand by a fire, creating the first glass. The Phoenicians produced three types of glass: transparent colorless glass used for mirrors and containers, translucent colored glass made into patterned bottles and vessels, and opaque glass which was rare and less attractive. Glass became an important Phoenician industry and they produced beads, ornaments, and imitation gems made of both transparent and colored glass.
Furniture show
The 25th International Contemporary Furniture Fair featured many unique pieces including dollhouse-size candelabras in hanging glass bulbs and wallpaper inspired by a 1909 article about a monkey in a bathhouse. However, the most eye-catching piece was Milton Glaser's collection featuring a colossal Shakespeare head emerging from an African carpet, reflecting Glaser's efforts to combine disparate objects without overwhelming the brain. There was widespread use of bronze, copper, and Swarovski crystals, reflecting the industry's emergence from recession. Many products also addressed environmental issues like sun protection and recycled plastics in outdoor furniture.

Glazing powerpoint
Glazing involves painting a thin layer of glass and minerals onto ceramic pieces. Underglaze can be applied all over while glaze cannot be applied to the bottom. Glazes have been used since ancient Egypt and were originally made from powdered glass and minerals. Ceramic pieces undergo bisque firing to strengthen them before glazing, which involves a second firing to fuse the glaze. It is important to take safety precautions like protective clothing and cleaning up spills when glazing ceramic pieces.

Mirrors were originally made of bronze by ancient Egyptians, Greeks, and Romans. In the 13th century, glass mirrors were first made in Venice and later produced in Britain in the 17th century. Today, mirror production is a major industry. Mirrors are made by coating a glass sheet with a thin layer of silver or aluminum through a chemical process. The backing is then painted for protection. Precise spraying or boiling of metallic solutions onto the glass produces the reflective surface. Once dry, mirrors are framed for use.
