Pontil Mark
A pontil mark or punt mark is the scar where the pontil, punty or punt was broken from a work of blown glass. The presence of such a scar indicates that a glass bottle or bowl was blown freehand, while the absence of a punt mark suggests either that the mark has been obliterated or that the work was mold-blown. Some glassblowers grind a hollow into the base of their work, obliterating the natural punt scar. Where the base of the work is sufficiently heavy, the entire natural base can be sawed or ground flat. Where the base of the work is concave, after the punt has been broken from the work, the punt may be used to attach a small gather of hot glass over the punt scar, into which a maker's mark is impressed. As commonly used in the collectibles and antiques industry, the term refers to the mark impressed on a blown glass item over this scar, since many notable glassblowers have impressed or engraved makers marks in the punt scars of their work.

Pontil
Glassblowing is a glassforming technique that involves inflating molten glass into a bubble (or parison) with the aid of a blowpipe (or blow tube). A person who blows glass is called a ''glassblower'', ''glassmith'', or ''gaffer''. A '' lampworker'' (often also called a glassblower or glassworker) manipulates glass with the use of a torch on a smaller scale, such as in producing precision laboratory glassware out of borosilicate glass. Technology Principles As a novel glass forming technique created in the middle of the 1st century BC, glassblowing exploited a working property of glass that was previously unknown to glassworkers; inflation, which is the expansion of a molten blob of glass by introducing a small amount of air into it. That is based on the liquid structure of glass where the atoms are held together by strong chemical bonds in a disordered and random network,Frank, S 1982. Glass and Archaeology.

Collectibles
A collectable (collectible or collector's item) is any object regarded as being of value or interest to a collector. Collectable items are not necessarily monetarily valuable or uncommon. There are numerous types of collectables and terms to denote those types. An antique is a collectable that is old. A curio is a small, usually fascinating or unusual item sought by collectors. A manufactured collectable is an item made specifically for people to collect.Danziger, Pamela (July 1, 1069)''Why People Buy Things They Don't Need: Understanding and Predicting Consumer Behavior'' Kaplan Publishing. The business of collectables Created to be collected A "manufactured" collectable (often referred to as a contemporary collectable) is an item made specifically for people to collect. Examples of items commonly sold as collectables include plates, figurines, bells, graphics, steins, and dolls. Some companies that produce manufactured collectables are members of The Gift and Collec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiques
An antique ( la, antiquus; 'old', 'ancient') is an item perceived as having value because of its aesthetic or historical significance, and often defined as at least 100 years old (or some other limit), although the term is often used loosely to describe any object that is old. An antique is usually an item that is collected or desirable because of its age, beauty, rarity, condition, utility, personal emotional connection, and/or other unique features. It is an object that represents a previous era or time period in human history. Vintage and collectible are used to describe items that are old, but do not meet the 100-year criterion. Antiques are usually objects of the decorative arts that show some degree of craftsmanship, collectability, or an attention to design, such as a desk or an early automobile. They are bought at antiques shops, estate sales, auction houses, online auctions, and other venues, or estate inherited. Antiques dealers often belong to national trade ass ...

Wine Bottle
A wine bottle is a bottle, generally a glass bottle, that is used for holding wine. Some wines are fermented in the bottle while others are bottled only after fermentation. Recently the bottle has become a standard unit of volume to describe sales in the wine industry, measuring . Wine bottles are produced, however, in a variety of volumes and shapes. Wine bottles are traditionally sealed with a cork, but screw-top caps are becoming popular, and there are several other methods used to seal a bottle. Sizes Many traditional wine bottle sizes are named for Biblical kings and historical figures. The chart below lists the sizes of various wine bottles in multiples relating to a standard bottle of wine, which is (six 125 mL servings). The "wineglassful"—an official unit of the apothecaries' system of weights—is much smaller at . Most champagne houses are unable to carry out secondary fermentation in bottles larger than a magnum due to the difficulty in riddling large, he ...

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 ...

Glass Art
Glass art refers to individual works of art that are substantially or wholly made of glass. It ranges in size from monumental works and installation pieces to wall hangings and windows, to works of art made in studios and factories, including glass jewelry and tableware. As a decorative and functional medium, glass was extensively developed in Egypt and Assyria. Glassblowing was perhaps invented in the 1st century BC, and featured heavily in Roman glass, which was highly developed with forms such as the cage cup for a luxury market. Islamic glass was the most sophisticated of the early Middle Ages. Then the builders of the great Norman and Gothic cathedrals of Europe took the art of glass to new heights with the use of stained glass windows as a major architectural and decorative element. Glass from Murano, in the Venetian Lagoon, (also known as Venetian glass) is the result of hundreds of years of refinement and invention. Murano is still held as the birthplace of modern ...
