Glass Engraver
Engraved glass is a type of decorated glass that involves shallowly engraving the surface of a glass object, either by holding it against a rotating wheel, or manipulating a "diamond point" in the style of an engraving burin. It is a subgroup of glass art, which refers to all artistic glass, much of it made by "hot" techniques such as moulding and blowing melting glass, and with other "cold" techniques such as glass etching which uses acidic, caustic, or abrasive substances to achieve artistic effects, and cut glass, which is cut with an abrasive wheel, but more deeply than in engraved glass, where the engraving normally only cuts deeply enough into the surface to leave a mark. Usually the engraved surface is left "frosted" so a difference is visible, while in cut glass the cut surface is polished to restore transparency. Some pieces may combine two or more techniques. There are several different techniques of glass engraving. It has been practised since ancient times, including ...

Abrasion (mechanical)
Abrasion is the process of scuffing, scratching, wearing down, marring, or rubbing away. It can be intentionally imposed in a controlled process using an abrasive. Abrasion can be an undesirable effect of exposure to normal use or exposure to the elements. In stone shaping Ancient artists, working in stone, used abrasion to create sculptures. The artist selected dense stones like carbonite and emery and rubbed them consistently against comparatively softer stones like limestone and granite. The artist used different sizes and shapes of abrasives, or turned them in various ways as they rubbed, to create effects on the softer stone's surface. Water was continuously poured over the surface to carry away particles. Abrasive technique in stone shaping was a long, tedious process that, with patience, resulted in eternal works of art in stone. Models The Archard equation is a simple model used to describe sliding wear and is based on the theory of asperity contact. Q = \frac H whe ...

Enamelled Glass
Enamelled glass or painted glass is glass which has been decorated with vitreous enamel (powdered glass, usually mixed with a binder) and then fired to fuse the glasses. It can produce brilliant and long-lasting colours, and be translucent or opaque. Unlike most methods of decorating glass, it allows painting using several colours, and along with glass engraving, has historically been the main technique used to create the full range of image types on glass. All proper uses of the term "enamel" refer to glass made into some flexible form, put into place on an object in another material, and then melted by heat to fuse them with the object. It is called vitreous enamel or just "enamel" when used on metal surfaces, and "enamelled" overglaze decoration when on pottery, especially on porcelain. Here the supporting surface is glass. All three versions of the technique have been used to make brush-painted images, which on glass and pottery are the normal use of the technique. Enam ...

Islamic Glass
The influence of the Islamic world to the history of glass is reflected by its distribution around the world, from Europe to China, and from Russia to East Africa. Islamic glass developed a unique expression that was characterized by the introduction of new techniques and the reinterpreting of old traditions. Roman and Sassanian influences Islamic glass did not begin to develop a recognizable expression until the late 8th or early 9th century AD, despite Islam spreading across the Middle East and North Africa during the mid-7th century AD.Israeli 2003, 319 Despite bringing enormous religious and socio-political changes to the region, this event appears to have not drastically affected the day-to-day workings of craft industries, nor did it cause "extensive destruction or long-lasting disruption". The Roman (Levant and Egypt) and Sassanian (Persia and Mesopotamia) glassmaking industries continued in much the same way they had for centuries. Following the unification of the entire ...

Goblet With Incised Designs MET H1 65
A chalice (from Latin 'mug', borrowed from Ancient Greek () 'cup') or goblet is a footed cup intended to hold a drink. In religious practice, a chalice is often used for drinking during a ceremony or may carry a certain symbolic meaning. Religious use Christian The ancient Roman ''calix'' was a drinking vessel consisting of a bowl fixed atop a stand, and was in common use at banquets. In Roman Catholicism, Eastern Orthodox Church, Oriental Orthodoxy, Anglicanism, Lutheranism and some other Christian denominations, a chalice is a standing cup used to hold sacramental wine during the Eucharist (also called the Lord's Supper or Holy Communion). Chalices are often made of precious metal, and they are sometimes richly enamelled and jewelled. The gold goblet was symbolic for family and tradition. Chalices have been used since the early church. Because of Jesus' command to his disciples to "Do this in remembrance of me." (), and Paul's account of the Eucharistic rit ...

Laser Engraving
Laser engraving is the practice of using lasers to engrave an object. Laser marking, on the other hand, is a broader category of methods to leave marks on an object, which in some cases, also includes color change due to chemical/molecular alteration, charring, foaming, melting, ablation, and more. The technique does not involve the use of inks, nor does it involve tool bits which contact the engraving surface and wear out, giving it an advantage over alternative engraving or marking technologies where inks or bit heads have to be replaced regularly. The impact of laser marking has been more pronounced for specially designed "laserable" materials and also for some paints. These include laser-sensitive polymers and novel metal alloys. The term laser marking is also used as a generic term covering a broad spectrum of surfacing techniques including printing, hot-branding and laser bonding. The machines for laser engraving and laser marking are the same, so that the two terms are ...

Glass Blank
A glass blank is a piece of glass that requires additional decoration before it is considered finished. Types of decoration include cutting, engraving, acid-etching, gilding, and enameling. Often the term blank is used in reference to an uncut piece of glass that will be cut or engraved. "Blank" is used in the same way of pottery, especially porcelain, that was often decorated elsewhere, for example by hausmalers. Production The glassmaking process can be divided into several stages, including: melting ingredients to make raw glass, remelting raw glass to make objects (sometimes adding decorations while the glass is still hot), and adding decorations to cooled glass objects. The last stage is often where blanks are involved. These are pieces of glass made with the intention of adding decoration to the cooled piece. Blanks are sometimes made in the same factory or studio in which they are decorated, but blanks can also be made and sold by one company to another company that adds de ...

Sandblasting
Sandblasting, sometimes known as abrasive blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants. A pressurised fluid, typically compressed air, or a centrifugal wheel is used to propel the blasting material (often called the ''media''). The first abrasive blasting process was patented by Benjamin Chew Tilghman on 18 October 1870. There are several variants of the process, using various media; some are highly abrasive, whereas others are milder. The most abrasive are shot blasting (with metal shot) and sandblasting (with sand). Moderately abrasive variants include glass bead blasting (with glass beads) and plastic media blasting (PMB) with ground-up plastic stock or walnut shells and corncobs. Some of these substances can cause anaphylactic shock to individuals allergic to the media. A mild version is sodablasti ...

Stipple
Stippling is the creation of a pattern simulating varying degrees of solidity or shading by using small dots. Such a pattern may occur in nature and these effects are frequently emulated by artists. Art In printmaking, stipple engraving is a technique using flicks of the burin to build up the image in short lines or dots, often combined with conventional linear engraving. In engraved glass a similar stipple technique has often been popular. In a drawing or painting, the dots are made of pigment of a single colour, applied with a pen or brush; the denser the dots, the darker the apparent shade—or lighter, if the pigment is lighter than the surface. This is similar to—but distinct from—pointillism, which uses dots of different colours to simulate blended colours. Botany In description of flora species, a stippling is a kind of pattern, especially in the case of flowering plants, produced in nature that occur on flower petals and sepals. These are similar to the dot pa ...
