Big secret of jewelers! How do they fix broken, tired gold?

- Опубликовано: 4 окт 2024
- Old jewelers used to clean it by throwing glass dust into it and melt it again because the chemistry of the constantly melted gold deteriorates and the gold is tired. In this section, you will see how it is done in the smallest details.

Thank you for your video. For those who are unfamiliar with gold smelting process, the addition of pulverized glass melted together with scrap gold forms what is known as slag. The molten slag absorbs impurities from the gold which increases in its purity.
Is it possible to clean slag with silver?
@@iehaningrad645 Thank you for your question. Silver can be purified by dissolving it in nitric acid. Then the silver nitrate solution is used in electrolysis whereby an impure silver ingot is connected to the anode and pure silver therefore gets plated onto the cathode. Similarly gold can also be purified by electrolysis which is known as the Wohwill Process. Impure gold is dissolved in Aqua Regia. In the electrolysis, an impure gold ingot is connected to the anode and pure gold therefore gets plated onto the cathode.
Does this work on Platinum?
@@jesscorbin5981 Platinum melts at 3,215° Fahrenheit (equivalent to 1,768° Celsius) as compared to Gold which melts at 1,948° Fahrenheit (equivalent to 1,064° Celsius). To melt Platinum would require a much hotter torch such as an Oxyacetylene torch capable of 3,590 °Fahrenheit (equivalent to 1,980° Celsius).

Saludos, seria interesante poder pesar el oro ANTES y DESPUES de esta tecnica, para poder apreciar la merma del proceso. Muchas gracias.

Use potassium nitrate (hindi name.. kalmishora..) during gold melting . Very easy and no west
I noticed you didn't measure that glass powder so I guess ratio isn't crucial but what approximately do you think the ideal ratio should be because you obviously have some sense of how much you want to put in there but didn't indicate what that is or how you determined it.
Minuto 1:35 ...Y sin gafas de protección, di que si machote bravo !!!!😱 Hete aquí el próximo candidato a vender cupones de la ONCE
Would any other forms of silica do the same thing?
Also worth mentioning I think that modern glass is different from the old school glass and different from but it glass and evidently whatever they put in that glass to make it green isn't a factor as I assume you could use clear glass blue glass or any other type of glass except maybe leaded glass and I wonder about the gold glass in the shielding for the Apollo missions to protect the astronauts from ultraviolet radiation and cosmic rays / ionizing radiation
yo creo que no es para arreglar si esta roto o desgastado, mas bien este proceso es para sacarle las impurezas
Cuando la fundición está mal hecha y mal purificada es cuando sale las escamas en las láminas o ilo , na sacaron las impurezas de hierro..
Great job well done sir
Now all I need is gold lol ..loved the video that's was a eye opener
Thank you. Wonderful video. I knew there was an old way just didn't know what it was. The chemical was the only way I could find.

Добрый день. Расскажите по подробнее как селитрой очищать метал - 585° золото.
Я использую поташ для очистки метала при плавке в буре...
They just wanted to show an antique alternative to clean the gold. That's why they used glass. Otherwise of course they know about modern chemical alternatives...
а серебро так можно почистить от шлака?
И всё же, что с селитрой делать!?
@@МаксимТабачинский-г3х , не понял сутки вашего вопроса ко мне...
1. Altın bozulmaz, ayrıca yorulmaz kullanım süreci içinde içine pislik, demir , parçacıkları toz halinde girer .
Cam tozu evet bir nebze temizler ancak en iyi temizleyici Bor madeni yani Boraxtır...Ayrıca erime esnasında borax ile temizledikten sonra Nişadur denilen bir başk kimyasal toz da katılır oda madenin yumuşaklık almasını sağlar.
Bu bilgiler 40 yıllık tecrübemdir.
Depois do processo com o pó do vidro, o ouro sai com qual teor?
Beautiful work ❣️
Nitric acid
the same and better saltpeter and potash
Great job👍
Kolay gelsin
yuğtupta geziniyorum altın eritme diye aratıyorum hem türkçe hem ingilizce. türkçe aratınca türkler çıkıyor altın eriten. 1000 derece potaya çıplak elle atıyorlar altınları. İstisnasız. Bir tane koruyucu eldiven giyen görmedim veya alet kullanan. Sanki o çıplak elle attığı için madalya takacaklar. İngilizce aratında da yabancılar çıkıyor. Hepsinde korucu eldiven, gözlük var. Her türlü güvenlik önlemi alınmış. Neden böyleyiz biz.
Hangi asitle temizleniyor?
Can silica be used instead of glass?
Terimakasih atas Petunjuknya
camı boraks yerine kullanıyorsunuz sanırım eriyip altını canağa yapıştırmıyor.
Muito bom nota 10000
the ancient goldsmith use brick powder and some amount of lead mixed with gold or silver to refine the same way video shows with glass powder.
What's the weight before and after ,
Does it work for scrap silver?
نعم
the ancient goldsmith use brick powder and some amount of lead mixed with gold or silver to refine the same way video shows with glass powder,the refine result was pure gold and pure silver,if they want only pure gold they add salt powder to the melted metal,that take out the silver as a silver chloride.
Çok iyii
Does this work on Platinum?
That was interesting.

What exactly is the glass doing pulling out impurities or something like that because you pull it back out before it ever became similar to the viscosity of the gold and maybe I missed it but I didn't see you use any flux like boric acid either
very nice sir
هل طريقة تفع فقط اذا خلط الذهب مع المواد العضوية
لكن لا بديل الا للحل في الحمض الملكي اذا خلط مع القصدير او الرصاص
El oro no se desgasta. Permanece igual por siglos… cuec!
لايوجد ضروره لتكسير الزجاج يكفي قليل منه مع اضافه حبوب .براسيتول. واظافه حجر مطحون قليل .يعني هذه المواد الثلاثه كافي لازاله الشوائب .واذا لم تنجح العمليه عليك في تصفيتها واعاده تركيبه عيارها المراد من جديد تحياتي.

Why use৷ the glass powder?
It attracts the lesser metals and impurities. Still do not have 24k at the end. Just the same karat 10k, 14k, 20, 22k. If you want pure gold you will need to use aqua regia, or cupel it
Cool but just get a box of borax for $2 US next time. Works way better.

similar to adding borax
no,borax only help to melt the metal,the glass powder purify, eleminate other metals than gold or silver.

friend, so that this does not happen, you must create a lubricant if it is industrial, taladrina is used, an oil that is mixed with ordinary or distilled water.
But for home-grade drawing or rolling tools that are not in continuous rolling, you must create dense amangama lubricants , Viscous or dense lubricants 1X1 cocoa fat and raffite powder = Viscous suitable for low temperatures. 1X1 Synthetic Acrylic Vaseline or Gynecological Vaseline and Graphite Powder This lubricant is good for hot days and chips . Roll damage occurs when one of the rolls does not rotate at the same torque as the drive roll. To improve the work, the chain sprocket and hydraulic sprocket gear system is eliminated. The total opening of the bearing guide erreje is a minimum rotational lamination of 0.12nm, a maximum of 12cm.

Ну и колдуны🤣🤣🤣В начале хотел сказать придурки, но сдержался. В своей зажни переплавил вдоль и поперек. Что только не делал… А работаю я с 1971 года. Есть способ, почистить загрязненное золото, но это делается с помощь медного купороса. Видео просто для болванов😡
Подскажите, а возможно бурой убрать, как бы так сказать в моем понимании "шлак "? Если автор видео хотел этого добиться с помощью битого стекла.
@@arekgloba2781 есть случаи, когда метал засоряется, разными посторонними металлами, или влияет лигатура, когда перемешиваешь разные металлы от клиентов. В таком случае помогает бура, смешанная с медным купоросом. Одна часть буры и пять частей медного купороса. При плавке нужно перемешивать все и процедуру повторить несколько раз. Переплавил, прокатал и опять переплавляешь с медным купоросом. Если не поможет, весь лом золото переплавляешь с медью до 230-250 пробы, прокатываешь как можно тоньше и все в азотную кислоту. После разедания металла до выпавшего бурого осадка, все промываешь водой, бурый осадок высушиваешь, добавляешь чуть буры и переплавляешь. Получается чистое золото и можешь делать что хочешь … Все занимает пару часов
