Brass Metals And Its History

Thursday, October 22nd, 2009

The most popular surviving form of brassware is probably the domestic candlestick. These were made usually in pairs, and are rarely older than the middle of the seventeenth century. At that time they were on domed circular bases, with a pan to catch drips of wax halfway up the stout central column. Early in the eighteenth century, shaped bases and tall stems with grease-pans at the very top came into fashion. With variations from time to time, this style continued in use until the candle was no longer the principal illuminant in the home.

Metal works
Brass was made into dishes of various sizes, often with embossed designs of Biblical scenes with inscriptions on the borders. These are sometimes still to be seen in use as alms-dishes in churches.

Chandeliers of brass with curved branching arms were made in England and also on the Continent. Many of them date from the seventeenth century, but most have been made more recently in response to continual demand.

Ormolu
This is the French name (literally or moulu, molded gold) for articles and furniture mounts made of bronze and gilded. The piece having been made in bronze was carefully and finely finished by chiseling and polishing and then coated with a mixture of mercury and gold. This amalgam was subjected to heat and the mercury evaporated leaving the gold deposited on the surface. Finally, the gold was burnished where required, or left matt.

The French developed the art of designing and making furniture mounts from ormolu, and were equally proficient at making clock cases, candlesticks, inkstands and other suitable pieces from the same material. Much thought was given to the mounting of porcelain in ormolu, and vases and figures with bases and other enhancements were valued highly for decoration. They fetch high prices today, but only if the mounts are genuinely of the eighteenth century. From 1745 to 1749 a tax was levied on ormolu, and pieces were stamped in a similar manner to silver. The mark is a letter ‘c’ beneath a crown, but as it was in use apparently for no more than four years specimens bearing it is rare.

German ormolu is not dissimilar to French, although seldom as highly finished. In England, the firm of Boulton and Fothergill, of Soho, Birmingham, made good ormolu at the end of the eighteenth century.

Old ormolu is sometimes found with the gilding in good condition, but frequently it is worn away on the surfaces exposed to by wear and tear; its greatest enemy is metal-polish, which should never be used on it. As with Sheffield plate, ormolu can be replated electrically but the appearance of the old cannot be reproduced exactly.

Beside brass ormolu, the French for articles and furniture mounts made of bronze and gilded, developed the French name. They developed the art of designing and making furniture mounts from this ormolu and they were equally proficient at making clock cases, candlesticks, inkstands and other suitable pieces from this material. Then the German and the English followed later on in the eighteenth.

Packaging Labels

Friday, September 4th, 2009

Packaging industry has seen a tremendous shift from ordinary packaging techniques to tailor made shapes, sizes and designs. And packaging labels are used on each and every product – both retail and wholesale. The importance of the right kind of packaging labels for retail products is evident from the fact that it is the packaging label that catches the consumer’s eye. The packaging label can actually make or break a sale.

Most manufacturers who deal in packaging labels carry a ready stock of various sizes of blank labels, adhesive and any other required paraphernalia. Product manufacturers usually get their product labels designed by specialists in the advertising field. A template is prepared and handed over to a packaging label manufacturer who then does the needful. Some packaging label companies offer innovative labels. By choosing such labels product manufacturers can do away with the cost of getting packaging labels designed.

Packaging labels have other uses too. They may be used for identification, inventory control and regulatory compliance. Special use packaging labels include serial number plates, instruction labels, shipping labels, fleet wraps and barcode labels. Product manufacturers should evaluate packaging labels services on the basis of product capabilities, specialties if any, quality requirements and the like.

Product capabilities of packaging label manufacturers include bar or matrix code labels, certification or regulatory code labels, decorative tape, embossed labels or seals, labels for instrument or control panels, laser printable labels, reusable containers, peel off labeling, thermal transfer tape and wash away labeling to name a few.

Laser printable labels are made in such a manner that they are suitable for going through a laser printer. This allows for customer specific labeling requirements to be processed. Labels used for instrumentation and control panels have instructions, graphics, etc. Thermal transfer tape is a type of labeling where a tape is firmly affixed onto the product surface with the use of heat and pressure. Wash away labels are used for containers that see multiple uses as long as they are in a usable condition.

Paper, plastic, metal, rubber and foam are some of the common materials used for the manufacture of packaging labels.
