I purchased this riveted mail hauberk a while back, the seller claimed it was found in Saudi by an Aramco worker, buried in the sand, while I have no idea if this story is true the hauberk was completely rusted over. I could see none of the usual details which would allow me to identify its origin. I could not see the type of rivets used or if it was completely riveted or if it had alternating rows of solid links. The basic shape did remind me on a very similar hauberk owned by Artzi which he says is Circassian work, the weight was over 20lbs.
I decided to use electricity to remove some of the rust, I was hoping to be able to remove enough to see some details. There are a lot of very detailed descriptions online for this rest removal method, after reading several I got my supplies together, a 5 gallon plastic bucket, 1 computer power supply with two clip ends for positive and negative, a couple of scrap metal pieces for scarificial electrodes, copper wire (steel is recommended), electrolite (Sodium Carbonate) in the form of "washing soda". I put the hauberk in the plastic bucket, and attached the negative wire to it, I then suspended several pieces of scrap metal around the inside of the bucket making sure that they did not touch the hauberk these were attached to the positive wire, I added water to the top with 1 table spoon of electrolite for each gallon. I plugged in the power supply (outdoors) and tiny bubbles started to appear, a sign that everything was connected correctly. It did not take long for a very thick surface of corrosion to appear on the top of the water which I poured off occasionally, after around 24 hrs I removed the hauberk and washed it off, I used a blower to get as much of the water off as I could before it started to rust again, which I was told would happen quite quickly, I then coated the entire surface with "Break Free" spray. The results were quite dramatic, I could now see that this was a very well made hauberk with alternating rows of solid links and what appears to be wedge riveted links, the links are very uniform in size and shape and quite well made. Normally wedge rivets would indicate European origin but there are some examples of Circassian mail with wedge riveting including a few examples in the Mets collection. European mail would not use alternating rows of solid links after around the late 14th to early 15th century but Indo-Persian mail commonly used solid links but with round rivets not wedge rivets. Circassians were known to make mail for the Ottomans but more research will be needed. I will have to do another round of rust removal, I will probably use the same method. |

Hi Estcrh.
WOW!! What a difference !!! Great job. That process really does work. Yes, another application would be worth a try. Would be interesting to see if a second application takes any more off. Another method I found very effective for removing loose, red rust is glass bead blasting (not sand blasting). You can set the air gun to very slow speed and remove as little or as much as you want. And it does so without removing the original patina. However, in the case of this Hauberk, with the small links close together, I would think that your electrolysis method would be easier and more effective. And it appears so. Again, great job. It still amazes me how long the Caucasions/Circasions continued to use mail armour. At least according to photographic evidence, all the up to the 1870/80's. Again, a really nice addition to your collection. Rick. |

I wasnt sure how far the rust went, luckly there is still a lot of metal left, I will post some additional pictures whenever I get around to treating it again. This method can be used on weapons as well, I have seen some really incredible results on dug up iron objects that were heavily corroded, also on old tools and auto parts. |

Below are some images of theta links from an Indian example and a report from the Royal Armouries. Notice the extreme small size of the individual links, making it next to impossible for even an arrow head to pass through. Quote:

There almost certainly had to be some type of die involved. The links are too perfectly round when compared to the riveted links. The edges appear to be perfectly square with the surface.
The consistent heat control and applied pressure during the welding process imply there could be a "trick" that we're overlooking. |

Here is a 17th century theta link mail and plate shirt, you can imaging how long it took to construct something like this from start to finish. |

I may as well include some images of standard Indo-Persian mail, which as I said before is usually constructed with alternating rows of solid links and round riveted links. Several types are easily recognized such as Indian mail and Ottoman mail. Below are some examples, the first is a 17th centur,y mail shirt detail, you can see the round riveted links and the very distinctive solid links which appear to be made from strips of welded metal and not wire, the red arrow shows delamination of the weld on a solid link.
Next is 16th century Ottoman cuirass, metal plates connected with a very distinctive mail, you can see the round riveted links and the solid links which instead of being round have the appearance of being faceted due to having flat areas on the outside of the links, I am not sure exactly how these Ottoman solid links were made but it is very recognizable. The third example is Indian mail but if you look at the links they appear to have been swaged / shaped in some way and are beautifully formed, they were not made from round wire as with most Indian riveted links. This is another example of a very time consumming process. I would have to assume that this type of mail was thought to be stronger then round wire links, I would also guess that this would have been much more expensive than the standard mail. |

Ah okay thanks for that. Also...One thing I have notice in images is that most wedge riveted I see is used on flattened rings. Whereas most round riveted is used on substantially thicker and usually round rings. Is this just confirmation bias or is this normal? and if normal is there a reasoning we know of behind it?

As for round riveted mail some links are thick, some are actually quite slender. I think that the use of the armor had a lot to do with how thick the mail was. A mail shirt made for light calvery would have been made from lighter links than a mail shirt made for someone who would be in heavy hand to hand fighting, just my opinion. Some Indo-Persian round riveted mail is made from flattened links as well as round links, there is a lot of variation. I have two pinterest links here one for European mail and one for Indo-Persian mail, you can see a huge variety of mail types with some good detailed images. https://www.pinterest.com/worldantiq...an-mail-armor/ https://www.pinterest.com/worldantiq...an-mail-armor/ |

Apologies for the late reply but I would like to thank you for your post which has answered my thoughts on how to clean my helmets with chain mail as I could not think of a suitable method until reading your post, thanks again.
