    Wow. Everyone's a critic. Great video, going to have to get some scrap copper wire, often the pieces they cut-off are that long or longer and even larger gauge, when working on the power lines.

    Hi, enjoying the videos. You might want to mention that this is only for non-ferrous metals. I came into metal from the ironworking side. Would love to see a video of making jewelry with pattern welded steel.

    to anneal metal you have to cool it slowly by earthier letting it air cool or put it in sand. just letting you know.

    • @OnlineJewelryAcademy

      It all depends on what you are preparing your metal to do. If you are trying to make it malleable, you need to inhibit the internal crystal growth by quenching the metal. If you are trying to grow larger crystals for reticulation, then you would let the metal air cool. If you are avoiding potential cracking then you might want to bury your item in a sand box. Remember, there often isn't just one correct way of doing things in the jewelry lab.

      To soften steel after heating, you let it air cool. But this video isn't about steel. It's about non ferrous metals, which soften when rapidly cooled.

    Hi John, Is there a good way to be sure that I have heated the metal long enough? I've heard somewhere that if you drop it on the floor and it makes a dull sound it's annealed. But maybe that will damage the floor or the metal...

      Hi Shannon,
      The way to tell if you have truly annealed a piece of metal is to see the material glow while you are heating it. For example, copper gives off a dark red or dull red glow when the material is at an annealing temperature. If you turn the lights off in your studio while you anneal, you'll always do it properly and never melt your pieces. Good luck with your projects.
      Thanks for watching! : )

    Does one need to pickle after using the flame? Is there anything that can protect the metal so we don't have to pickle the metal piece after annealing?

    • @OnlineJewelryAcademy
      @OnlineJewelryAcademy  7 лет назад

      Hi Allen, Generally, jewelers and metalsmith will pickle items after every application of heat to an item. This helps to keep the work clean. And that helps one to avoid mistakes. Plus, it keeps oxides from ruining your tools.

    By the way, I thought that quenching the metal would harden it, could you explain it to me?
    I an currently trying to make a mail shirt out of steel rings, and they need to be annealed.

    • @OnlineJewelryAcademy
      @OnlineJewelryAcademy  7 лет назад +1

      Hi Astaziel, Ferrous metals, those containing iron, will harden with quenching. Precious metals such as gold and silver will soften with quenching. This is also true of copper and its alloys. This is because the quick chilling of the precious metal will inhibit the development of large crystals within the material. To grow the metal crystals for tasks like reticulation, you simply let the precious metal air cool after annealing.

      Astaziel which steel will You be annealing? that steel rings for mail shirts are commonly produced from very low carbon steel, that are very ductile and cannot be hardened.

    • @astaziel3165
      @astaziel3165 7 лет назад

      I am not looking to harden the steel, but to anneal it

    • @lukkwi
      @lukkwi 7 лет назад

      My point was, that if your steel cannot be hardened, then it is a good chance, that it will be good to machine anyway (for low carb steels there is however such thing as process annealing) :)
      You gave a question that cannot be answered without specifying type of steel you will be using.
      Was trying to help anyway, cheers:)

    Can you use a micro torch like this one to anneal copper, brass and silver. Blazer GT8000 Big Shot Micro torch. Anti-flare, brass-frame nozzle, for safety and flame controlAttachable tabletop base, for hands-free useGas-flow adjustment dial, to control flame lengthPiezoelectric ignition system, requires no electrical connection2,500-degree F, torch flame, for a more precise flame tipI appreciate your help. Thank you.

    • @OnlineJewelryAcademy
      @OnlineJewelryAcademy  8 лет назад

      Hi Kendra, a micro torch is only going to effectively anneal small pieces of metal. Most jewelry studios have a larger torch for annealing purposes. You can find an inexpensive torch for this purpose at most hardware stores. Remember to practice good fire safety.

      Hi Ronald, This process will work for "nickel silver". Personally I never work with the stuff. It's way too hard for my liking. Plus, some people have an allergy to it.

    If it were iron or steel, quenching it quickly may harden it. This is not true with copper like you have there?

    • @OnlineJewelryAcademy
      @OnlineJewelryAcademy  9 лет назад

      +newstart49 Correct. But you can also allow the copper to cool slowly if you prefer and still achieve the same result. Thanks for watching! : )

    The point of annealing is to let it air cool, not quench it..

    • @OnlineJewelryAcademy
      @OnlineJewelryAcademy  7 лет назад +3

      First, love the Pickle Rick image. Second, annealing for jewelry that uses nonferrous metals does allow one to quench or air cool. It all depends on whether or not you want small or large internal crystal growth.

      I took about 2.5 years worth of metals classes in college, most people just went from the fire brick to the pickle pot. The goal is to soften metal to be able to work it properly, This tutorial brings back good memories.

      That's just for iron and steel. The other metals stay soft when quenched.

    I’m not familiar with working copper but with most metals quenching hardens it. Doesn’t that defeat the softening you just did? With steel I’ve seen it heated to non magnetic then cooled slowly in perlite or ashes so that it stays soft when cool. Is copper different?

    • @OnlineJewelryAcademy
      @OnlineJewelryAcademy  6 лет назад +2

      Hi Chris, Here's a link to an OJA video that will answer your question thoroughly: ruclips.net/video/mtZZOd8_CAU/видео.html Nonferrous metals react differently to heating and quenching.

    • @MikeBSc
      @MikeBSc 10 месяцев назад

      Only ferrous metals harden through quenching. There are more non ferrous metals than ferrous, so technically, most metals stay soft as a result of quenching.

    Ummmmmm you let it air cool. You don't quinch it. Quinching makes it harder. And you definitely DO NOT quinch in water. You quinch in canola oil, motor oil, or commercial grade quinching oil. Just be sure that the canola oil is preheated to around 150-180 degrees. Water quinching can break the steel by cooling it way to fast..

    • @OnlineJewelryAcademy

      Hi Keith, The OJA has a video entitled "To Quench Or Not To Quench". We made that video because we receive a number of comments like yours. Ferrous materials, those that contain iron, are handled in the manner that you described. But, nonferrous materials like copper, brass, gold and silver can be quenched in water. Sometimes an alcohol quench for metals like white gold is preferred. But, the information in the video is correct.
      Thanks for your support! : )

      This video is about non ferrous metals, which do typically remain soft when quenched.
