Etcher
Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio (incised) in the metal. In modern manufacturing, other chemicals may be used on other types of material. As a method of printmaking, it is, along with engraving, the most important technique for old master prints, and remains in wide use today. In a number of modern variants such as microfabrication etching and photochemical milling, it is a crucial technique in modern technology, including circuit boards. In traditional pure etching, a metal plate (usually of copper, zinc or steel) is covered with a waxy ground which is resistant to acid. The artist then scratches off the ground with a pointed etching needle where the artist wants a line to appear in the finished piece, exposing the bare metal. The échoppe, a tool with a slanted oval section, is also used for "swelling" lines. The plate is then dipped in a bath of acid, kn ...

Old Master Print
An old master print (also spaced masterprint) is a work of art produced by a printing process within the Western tradition (mostly by Old Masters). The term remains current in the art trade, and there is no easy alternative in English to distinguish the works of "fine art" produced in printmaking from the vast range of decorative, utilitarian and popular prints that grew rapidly alongside the artistic print from the 15th century onwards. Fifteenth-century prints are sufficiently rare that they are classed as old master prints even if they are of crude or merely workmanlike artistic quality. A date of about 1830 is usually taken as marking the end of the period whose prints are covered by this term. The main techniques used, in order of their introduction, are woodcut, engraving, etching, mezzotint and aquatint, although there are others. Different techniques are often combined in a single print. With rare exceptions printed on textiles, such as silk, or on vellum, old master print ...

Rembrandt
Rembrandt Harmenszoon van Rijn (; ; 15 July 1606 – 4 October 1669), mononymously known as Rembrandt was a Dutch Golden Age painter, printmaker, and Drawing, draughtsman. He is generally considered one of the greatest visual artists in the history of Art of Europe, Western art.Gombrich, p. 420. It is estimated that Rembrandt's surviving works amount to about three hundred paintings, three hundred etchings and several hundred drawings. Unlike most Dutch painters of the 17th century, Rembrandt's works depict a wide range of styles and subject matter, from portrait painting, portraits and self-portraits to landscapes, genre scenes, allegorical and historical scenes, biblical and mythological subjects and animal studies. His contributions to art came in a period that historians call the Dutch Golden Age. Rembrandt never went abroad but was considerably influenced by the work of the Italian Old Masters and Bentvueghels, Dutch and Flemish artists who had studied in Italy. A ...

Intaglio (printmaking)
Intaglio ( ; ) is the family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink. It is the direct opposite of a relief print where the parts of the matrix that make the image stand ''above'' the main surface. Normally copper, or in recent times zinc, sheets called plates are used as a surface or matrix, and the incisions are created by etching, engraving, drypoint, aquatint or mezzotint, often in combination. Collagraphs may also be printed as intaglio plates. After the decline of the main relief technique of woodcut around 1550, the intaglio techniques dominated both artistic printmaking as well as most types of illustration and popular prints until the mid 19th century. The word "intaglio" describes prints created from plates where the ink-bearing regions are recessed beneath the plate's surface. Though brass, zinc, and other materials are occasionally utilized, copper is the most commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engraving
Engraving is the practice of incising a design on a hard, usually flat surface by cutting grooves into it with a Burin (engraving), burin. The result may be a decorated object in itself, as when silver, gold, steel, or Glass engraving, glass are engraved, or may provide an Intaglio (printmaking), intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engravings, a form of relief printing and stone engravings, such as petroglyphs, are not covered in this article. Engraving was a historically important method of producing images on paper in artistic printmaking, in mapmaking, and also for commercial reproductions and illustrations for books and magazines. It has long been replaced by various photographic processes in its commercial applications and, partly because of the difficulty of learning the techni ...

Etching (microfabrication)
Etching is used in microfabrication to chemically remove layers from the surface of a wafer (electronics), wafer during manufacturing. Etching is a critically important process module in fabrication, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching. In some cases, the masking material is a photoresist which has been patterned using photolithography. Other situations require a more durable mask, such as silicon nitride. Etching media and technology The two fundamental types of etchants are liquid-phase ("wet") and plasma (physics), plasma-phase ("dry"). Each of these exists in several varieties. Wet etching The first etching processes used liquid-phase ("wet") etchants. This process is now largely outdated but was used up until the late 1980s when it was superseded by dry plasma etching. The wafer can be immersed in a bath of etchant, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Egypt
Ancient Egypt () was a cradle of civilization concentrated along the lower reaches of the Nile River in Northeast Africa. It emerged from prehistoric Egypt around 3150BC (according to conventional Egyptian chronology), when Upper and Lower Egypt were amalgamated by Menes, who is believed by the majority of List of Egyptologists, Egyptologists to have been the same person as Narmer. The history of ancient Egypt unfolded as a series of stable kingdoms interspersed by the "Periodization of ancient Egypt, Intermediate Periods" of relative instability. These stable kingdoms existed in one of three periods: the Old Kingdom of Egypt, Old Kingdom of the Early Bronze Age; the Middle Kingdom of Egypt, Middle Kingdom of the Middle Bronze Age; or the New Kingdom of Egypt, New Kingdom of the Late Bronze Age. The pinnacle of ancient Egyptian power was achieved during the New Kingdom, which extended its rule to much of Nubia and a considerable portion of the Levant. After this period, Egypt ...

Ground (etching)
A ground is waxy material applied to the surface of a metal etching plate. A metal etching plate is a piece of sheet metal, usually copper, zinc, steel, or aluminium. The ground resists the acid or mordant which is used for etching, protecting areas of the metal plate. Grounds are made from a variety of materials including tar, asphaltum, paint (including spray paint), oil pastels, and other materials manufactured specifically for etching. Most commonly, a ground is applied evenly over the surface of the metal sheet (also known as the etching plate), and then removed using scratching and other mark making techniques to reveal bare metal underneath. In the traditional technique this is done with a metal needle. However, different grounds enable the artist to create different types of marks. Some types of grounds, such as an aquatint Aquatint is an intaglio printmaking technique, a variant of etching that produces areas of tone rather than lines. For this reason it has mostly ...

Carnelian
Carnelian (also spelled cornelian) is a brownish-red mineral commonly used as a semiprecious stone. Similar to carnelian is sard, which is generally harder and darker; the difference is not rigidly defined, and the two names are often used interchangeably. Both carnelian and sard are varieties of the silica mineral chalcedony colored by impurities of iron oxide. The color can vary greatly, ranging from pale orange to an intense almost-black coloration. Significant localities include Yanacodo (Peru); Ratnapura (Sri Lanka); and Thailand. It has been found in Indonesia, Brazil, India, Iran, Russia (Siberia), and Germany. In the United States, the official State Gem of Maryland is also a variety of carnelian called Patuxent River stone.

Indus Valley Civilization
The Indus Valley Civilisation (IVC), also known as the Indus Civilisation, was a Bronze Age civilisation in the northwestern regions of South Asia, lasting from 3300 BCE to 1300 BCE, and in its mature form from 2600 BCE to 1900 BCE. Together with ancient Egypt and Mesopotamia, it was one of three early civilisations of the Near East and South Asia, and of the three, the most widespread, its sites spanning an area including much of Pakistan, northwestern India and northeast Afghanistan. The civilisation flourished both in the alluvial plain of the Indus River, which flows through the length of Pakistan, and along a system of perennial monsoon-fed rivers that once coursed in the vicinity of the Ghaggar-Hakra, a seasonal river in northwest India and eastern Pakistan. The term ''Harappan'' is sometimes applied to the Indus Civilisation after its type site Harappa, the first to be excavated early in the 20th century in what was then the Punjab ...

Harappa
Harappa () is an archaeological site in Punjab, Pakistan, about west of Sahiwal, that takes its name from a modern village near the former course of the Ravi River, which now runs to the north. Harappa is the type site of the Bronze Age Indus Valley Civilisation ("IVC"), as it was the first IVC site to be excavated by the Archaeological Survey of India during the British Raj, although its significance did not become manifest until the discovery of Mohenjo-daro some years later. For this reason, IVC is sometimes called the "Harappan civilisation," a term more commonly used by the Archaeological Survey of India after decolonization in 1947. The discovery of Harappa and, soon afterwards, Mohenjo-Daro, two major urban settlements of IVC, was the culmination of work that had begun after the founding of the Archaeological Survey of India in 1861. The city of Harappa is believed to have had as many as 23,500 residents and occupied about with clay brick houses at its greatest extent ...
