Copper is a prevalent metal for manufacturing pots, utensils, jewellery and coins. Since copper can infrequently adopt a yellow or orange patina after some years of utilization, it can be easy to confuse it with metal or another metal. Yet, copper has a couple of exceptional qualities that separate it from different metals, and that can enable you to decide whether something is copper or some other metal. When in doubt, a chemical test should be possible to let you know for the last time what kind of metal a specific piece is.
1. The magnet test – Place a magnet on the surface of the thing. Copper isn’t magnetic so if the magnet attracts, you can make sure that it isn’t copper.
2. The colour test – Look at the shade of the cleaned piece. Copper has a characteristic pink tone that can obscure to look red, yellow or orange after some time. Have the piece professionally cleaned so as not to change the finish of the piece, and afterwards see it identify the pink tone. You might need to contrast the shading with a recently printed penny; it ought to be generally a similar shading.
3. The exposure test – Search for zones of the piece that have turned green. At the point when presented with abundance water or oxygen when incomplete, copper can turn green or dark over spots where it has been unnecessarily dealt with. Those dim spots can enable you to decide whether you are holding a genuine copper piece or not.
4. The sound test – Test the quality and the sound of the piece. Search for dents and wrinkles in the surface of the piece. Copper is famously delicate, so it can be hard to keep a piece impeccably smooth when working with it. On the off chance that the copper piece is sufficiently thin, you may even have the capacity to twist it with your uncovered hands. You may likewise thump on the piece and tune in to the sound that it makes. Genuine copper will have a profound and smooth sound, rather than metal, which can be sharp and tinny.
5. Observe the mark – Inspect the piece for a producer’s check. On the off chance that you discover one, you can follow it back to decide whether the craftsman fundamentally worked with copper pieces. Additionally, a few metals are controlled by the Unified Numbering System. Copper isn’t. If your item has a letter ‘C’ stamped on it, trailed by numbers, it is likely metal and not copper.
