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 ...

Glass
Glass is a non-crystalline, often transparent, amorphous solid that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as volcanic glass are naturally occurring. The most familiar, and historically the oldest, types of manufactured glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. Soda–lime glass, containing around 70% silica, accounts for around 90% of manufactured glass. The term ''glass'', in popular usage, is often used to refer only to this type of material, although silica-free glasses often have desirable properties for applications in modern communications technology. Some objects, such as drinking glasses and eyeglasses, are so commonly made of silicate-based glass that they are simply called by the name of the material. Despite bei ...

Cut Glass
Cut glass or cut-glass is a technique and a style of decorating glass. For some time the style has often been produced by other techniques such as the use of moulding, but the original technique of cutting glass on an abrasive wheel is still used in luxury products. On glassware vessels, the style typically consists of furrowed faces at angles to each other in complicated patterns, while for lighting fixtures, the style consists of flat or curved facets on small hanging pieces, often all over. Historically, cut glass was shaped using "coldwork" techniques of grinding or drilling, applied as a secondary stage to a piece of glass made by conventional processes such as glassblowing. Today, the glass is often mostly or entirely shaped in the initial process by using a mould (pressed glass), or imitated in clear plastic. Traditional hand-cutting continues, but gives a much more expensive product. Lead glass has long been misleadingly called "crystal" by the industry, evoking the gl ...

Glass Engraving
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, includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass Etching
Glass etching, or "French embossing", is a popular technique developed during the mid-1800s that is still widely used in both residential and commercial spaces today. Glass etching comprises the techniques of creating art on the surface of glass by applying acidic, caustic, or abrasive substances. Traditionally this is done after the glass is blown or cast, although mold-etching has replaced some forms of surface etching. The removal of minute amounts of glass causes the characteristic rough surface and translucent quality of frosted glass. Techniques Various techniques are used to achieve an etched surface in glass, whether for artistic effect, or simply to create a translucent surface. Acid etching is done using hexafluorosilicic acid (H2SiF6) which, when anhydrous, is colourless. The acid can be prepared by mixing quartz powder (silicon dioxide), calcium fluoride, and concentrated sulfuric acid; the acid forms after the resulting mixture is heated and the fumes (silicon tetra ...

Gilding
Gilding is a decorative technique for applying a very thin coating of gold over solid surfaces such as metal (most common), wood, porcelain, or stone. A gilded object is also described as "gilt". Where metal is gilded, the metal below was traditionally silver in the West, to make silver-gilt (or ''vermeil'') objects, but gilt-bronze is commonly used in China, and also called ormolu if it is Western. Methods of gilding include hand application and gluing, typically of gold leaf, chemical gilding, and electroplating, the last also called gold plating. Parcel-gilt (partial gilt) objects are only gilded over part of their surfaces. This may mean that all of the inside, and none of the outside, of a chalice or similar vessel is gilded, or that patterns or images are made up by using a combination of gilt and ungilted areas. Gilding gives an object a gold appearance at a fraction of the cost of creating a solid gold object. In addition, a solid gold piece would often be too soft or ...

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 ...

Porcelain
Porcelain () is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between . The strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste, and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions. Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago; it slowly spread to other East Asian countries, then to Europe, and eventually to the rest of the world. Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it ...

Hausmaler
In pottery hausmaler () is a term for the artist, the style, and the pieces in hausmalerei, the process of buying pieces of pottery as plain "blanks", and then painting them in small workshops, or the homes of painters, before a final firing. In European pottery of the 17th to 19th centuries this was at certain times and places a significant part of production, and the decoration could be of very high quality. In England this was referred to as "outside decoration" and was also very important in the 18th and early 19th century, with some revival in the 20th. Hausmalerei began with freelance glass enamelers in Bohemia but developed in Germany on white tin-glazed earthenware in the 17th century, when glazed and fired but unpainted wares "in the white" were purchased on speculation by unsupervised freelance ateliers of china painters, who decorated them in overglaze enamel colours and gilding, which were fixed by a further light firing in their own small kilns. A few such freelan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
