What is international deep silver flatware?

International deep silver or deep silver was a marketing slogan used by International Silver (IS) to represent a new line of silver-plated flatware, known as deep silver flatware, it was crafted to last longer than the standard silver plate. Deep Silver has a thicker layer of silver plating than the commonly used. It also features a minute amount of welded silver at the high points that receive the maximum wear.

The primary objective of the deep silver was that this silver plating was that it would long last and would stand up to more use. Deep Silver is better than the commonly used silver plating, but flatware made with this technique does not contain a good number of recoverable silver and therefore it has little resale market value.

There are two types of silverware available in the market. The one is made with 92.5% silver also known as “Sterling Silver” and the other looks like silver but in reality, is silver plated. For a common person, it is hard to differentiate between these two different types of silverware. Following are a few techniques that can be used to find the difference and find out if your silverware is actually silver.

How to find if silverware is silver not plated?

The first and most important one is to find out and do some research about the manufacturer. There are many companies out there that only deals with silver-plated flatware. If your product is one of them then it is silver plated.

If you purchase your product from an American manufacturer there are chances that it will have the marking of sterling or 925 somewhere embossed near the handle of the cutlery. All the sterling wares manufactured after the 1850s will have a marking of “sterling” or “925”. Sterling is silver with 92.5% pure silver, and 7.5% copper and it may contain a small number of other elements. The absence of these markings means that your silverware is not real silver, but silver plated.

Flatware from England will have symbols, numbers and letters stamped on it. There are different numbers and symbols with different meanings indicating the amount of silver in that flatware. The best way to know the exact meaning of these is to look those up online and find out if they are silver or plated.

The use of a magnet is also one of the best ways to test the steel. Pure silver and other silver alloys such as sterling silver are non-magnet and will not respond to it. Other steels like carbon steel will attract a magnet due to the less amount of silver and higher number of other magnetic steel in its composition. stainless steel is generally thought of as non-magnetic, but some low-quality steel will be picked up by the magnet. In the same way Brass, Bronze and Copper will also not respond to a magnet. In short, if it is not picked up by a magnet then it is not pure or sterling silver, but this does not guarantee that every non-magnetic silverware is actually silver or sterling. Other factors cannot be ignored before concluding.

 Color and shine are vital aspects to look for. Carefully examine the coloring and shining of the flatware. If it is less shiny and colder in tone, then it is sliver. If you notice someplace where it appears to be flaking off or turning green, then the product is silver plated.
