Frequently one finds that sellers guess-timate the age of a piece to show the item in its most favorable light. Weekend collectors–in a post-brunch glow and accompanied by a charming companion–are all too ready to hear the best of an object that has attracted their attention. As we say on the Street: That’s what makes a trade. But my column is about investment in tangibles–not about entertainment. If you are investing in an object for resale, it is useful to have something more concrete than a distant memory of a hopeful conjecture an enthusiastic dealer made in passing.

If limited strictly to religious practices, an inventory of ceremonial and ritualistic objects remains incomplete, because these objects have played significant roles on solemn secular occasions, such as consecrations, enthronements, and coronations, which may be closely linked to the divine order, as in Hindu -, Buddhist-, and Christian -influenced cultures. Icons and symbols Constituting a most-significant category of cult objects are representations of a deity. Though such representations are often depicted in the form of statues and images icons of divine or sacred beings, they may also be either figurative or symbolic , the meanings often being equivalent.

How can we age metal items? by How It Works Team · 28/01/ There isn’t an intrinsic method of dating metal as there is for wooden objects such as radiocarbon-dating or tree-ring dating.

Plating is a process dating back to the s. It is a coating of a layer of one metal deposited onto another using an electrically charged chemical bath. In the case of silver, it allowed the average person to possess objects that, made out of solid silver, had only been available to the wealthy. An item is first created out of a “base metal” such as copper, brass, nickel silver, brittania, or white metal alloys. It is then highly polished, submerged in the bath containing silver solution and solid silver , electrically charged for approximately one-half hour, and then repolished.

Some modern-day companies first apply a heavy layer of nickel to avoid the time-consuming buffing process then a light layer of silver. We do it the old-fashioned way – careful preparation with a thick silver plate which gives the job a deep, realistic appearance and should last a good twenty years. The same applies to our brass, copper, and gold plating.

Keep in mind that if something is solid brass or sterling silver, it does not require plating, just a professional cleaning and polishing.

History[ edit ] Although forms of brass have been in use since prehistory , [39] its true nature as a copper-zinc alloy was not understood until the post medieval period because the zinc vapor which reacted with copper to make brass was not recognised as a metal. Many have similar tin contents to contemporary bronze artefacts and it is possible that some copper-zinc alloys were accidental and perhaps not even distinguished from copper.

There is good archaeological evidence for this process and crucibles used to produce brass by cementation have been found on Roman period sites including Xanten [66] and Nidda [67] in Germany , Lyon in France [68] and at a number of sites in Britain. The fabric of these crucibles is porous, probably designed to prevent a buildup of pressure, and many have small holes in the lids which may be designed to release pressure [68] or to add additional zinc minerals near the end of the process.

Dioscorides mentioned that zinc minerals were used for both the working and finishing of brass, perhaps suggesting secondary additions. These places would remain important centres of brass making throughout the medieval period, [82] especially Dinant. Brass objects are still collectively known as dinanterie in French.

Detailed scientific manuals and handbooks,elaborately decorated magic medicine bowls, talismans and amulets, and rare alchemical equipment, as well as delicately produced globes mapping stars and constellations across the skies, add to this incomparable collection of scientific instruments and tools.

Many of these have not been studied in great detail, and although their function and purpose may still remain an enigma to scholars of Islamic art and history today, there is no doubt that these objects were essential and reflect the necessity of science in everyday life for any individual, regardless of their status in society.

Screws are relative newcomers to the production of furniture primarily because they are so hard to make by hand. But as the complexity and sophistication of furniture increased in the late 17th century and the use of brass hardware, locks and concealed hinges became more popular, there was an obvious need for a fastener that could hold two surfaces together without having to penetrate the back surface of the second piece.
