I'm writing a novel in which an artifact from a sunken ship comes into play. I was imagining something made of brass, bronze, or copper. The shipwreck area is Lake Superior, which has a temperature ranging from degrees F degrees C.
The depth of the wreck is at my discretion, as this is fiction. However, I like to be as accurate as possible.
Tarnish, corrosion, etc. I had considered using a wooden box with metal components, but I feel that might deteriorate significantly. Thanks for your help! It's only a guestimate, of course, but after years submerged in cool fresh water, a small coin sized piece of brass would probably be corroded beyond recognition. Bronze or copper would survive in much better condition, original imprints likely being discernible. Of course it depends on the composition of objects made long ago, and the conditions - was it buried in mud, subject to tidal action?
If your scenario depends on the object being in recognizable, possibly usable condition, I'd go with bronze, although copper might do about as well.
If your scenario changes to warm, tidal saltwater, then bronze. You may want to take a look at the Riace Bronzes that were found in in the sea near Italy and date from the 5th Century BC.
They likely have been in the water for at least a couple of thousand years. Hi there. I was just at the Athenian Archeology museum researching this very issue. They have several recovered sculptures in marble and brass with extreme underwater fresh and sea water corrosion.
I sent some images to this finishing site: Best Raphael. Secondly, you might like to look up 'antikythera mechanism' Images and fascinating videos of reconstruction - and food for thought for a writer.
Hi I found a pot buried in my back garden. It must have been buried for at least 20 years. I cleaned it up and now it is sparkling.
This process is vital as it will ensure that the gold forms a perfect bond when plated on brass. The next step is to plate the brass with nickel. This is done to protect the final gold layer from being affected by the base metal brass. In raw form, brass will leech on gold hence reducing its lifespan. The final step is to dip gold into a gold solution that contains electric charges. This allows the electroplating process to take place whereby the brass will be fully coated with gold.
Generally, gold plated brass jewelry is capable of lasting for up to two years. After that, the jewelry will lose its luster and start fading quite fast.
Keep in mind the lifespan of a gold plated jewelry is calibrated by the amount of gold that is remaining on the base metal. This means that it will take quite long before the layer of gold is completely depleted on the brass.
So, if you want a gold plated brass that will last for long, you better choose one that is quite thick. Another obvious factor that will determine how long your gold plated bras will last is your frequency of wearing the jewelry. Also, how you handle your gold plated brass jewelry will have an impact on its lifespan.
Since gold is pretty soft, try to handle it smoothly. Store it in a safe place where it will be protected from corrosion and abrasion. As we have discussed, the thickness is one of the key factors that determine the durability of a gold plated brass. Did you know that, in addition to zinc and copper, brass can also contain nickel, one of the most serious causes of allergic reactions out there?
The reason why brass causes your body to flare up is actually fairly fascinating. Your body feels that the brass, and the metals it contains, could harm you, and so your immune system goes into overdrive. Especially if you're wearing these jewels for long periods of time, this allergy can only get worse. If you're experiencing itching, redness, or even a rash, even two days after you've worn brass, it's likely the cause of what ails you. Brass has even been known to cause blistering - something you definitely don't want to happen the night before a big party or meeting!
If brass gets you, in addition to stopping wearing and buying it, we recommend that you rub a little cortisone on it - and try to keep your hands off the affected area. On a more serious note, brass can also really cause any pre-existing lung or breathing issues you may have to flare up. In fact, this discovery was made after musicians playing brass instruments reported issues with breathing that resulted from bacteria and mold growing in the pipes of their instruments.
While cleaning your brass jewelry may be enough for some people, for most of us, wearing something that could make us sick just isn't worth the risk. So, what can you buy instead of brass jewelry?
We've already emphasized that it's crucial to focus on jewelry as a long-term investment. While the style of jewelry you buy will depend on your personal preference, some of the materials we suggest are:. With so many fabulous options at your fingertips, why waste another minute dealing with the hassles and problems of brass jewelry?
Treat yourself to something special, that you can wear for years. No matter what kind of style, budget, or event you're trying to find a piece for, don't settle for brass just because it's the cheapest option available. While that all sounds perfect, there is a drawback with plating. It is guaranteed that the metal coating the metal at the base will eventually wear away. That is why you want to invest in plated jewelry that has a thicker layer of, for example, gold. Yes, you can gold plate brass.
A jeweler can gold plate almost any metal, copper , nickel , and silver included. You will also find that gold is not the only metal used to coat brass. It is common practice for those in the industry to use nickel or copper to plate the brass to give it strength and reduce the tarnishing consecutively. It is easier for them when the item has not been plated before.
You can talk to them about the thickness that you need to achieve the desired effect. That does mean parting with more money than you might anticipate. Do note that even when that happens, you have to know that it will not hold as well, for example, like silver or titanium. Therefore, you have to decide if it is worth the investment to gold plate your nickel or do that to another metal instead.
As mentioned, the gold plated brass jewelry will fade, or rather, tarnish.
