Melting Silver – Periodic Table of Videos

Melting Silver – Periodic Table of Videos


hi I’m Brody and you might remember last year the professor met a man named max Whitby the element collector he’s a guy who makes real-life periodic tables and we remember what max told us I’ll invite you to our lab and see something melted this is quite a test quite a nice thing to see so I’ve been down to London to make a few videos with Max and well here’s the first one where in the world headquarters of the red green and blue company RGB research which is where we make our periodic tables the displays that we make here are really mainly for museums and for schools and occasionally for very wealthy individuals who fancy a periodic table in their study and actually what I’m about to do now is to go and make a sample to go into one of these periodic tables this is what we’re starting with and it’s a beautiful one kilogram jar of silver sadly if I bought this about a year ago I could have got it for maybe 200 pounds but now silver shot up in price this is one of the terrible problems of being in the element selling trade and now this is almost a thousand pounds worth of silver and what I’m going to do I hope is to turn it into a beautiful cylinder this is even more expensive yeah feel the weight just feel the way to that yeah well what you’re looking at is pure gold so that’s one kilogram cylinder and if we make an equivalent sized cylinder and silver it’s going to be about half the weight it’s going to be about half a kilogram so I’m hoping I can get two cylinders out of this now the very first step in making a cylinder do you know what it is you have to do a risk assessment because what we’re doing is dealing with hot molten metal and so we’ve actually gone through quite carefully thinking of all the things that can go wrong and brady we’ve actually had a chat about that that’s what i’m going to be standing at here and I’m going to load the furnace see that’s blowing nicely red hot this is a graphite crucible in fact stay there I’m going to turn the light out is that glowing still yeah so that that is hot I’ve set that to 1050 degrees centigrade so it’s quite a bit above the melting point of silver so I’m going to start by filling that up and now of course doing this is going to reduce the temperature very considerably so once we filled it up with the pieces of silver we then you can actually see it cooling and silvers a superb conductor of heat that’s got you know quite a lot of thermal inertia you can see that’s gone almost now back to the color of graphite because all the heat that was in the graphite is gone into the silver very very quickly superb conductor and now we’re going to close a little lid and leave it to leave its cook so well this is slightly overkill but it provides a full face mask gloves again and fingers crossed fantastic now that’s the sinkhole appearing hopefully that will fill up the sinkhole okay well I’m very relieved that seems to have come out okay spill I’m making jelly only a thousand degrees Celsius more now what’s going to happen is that’s going to cool down and then we’ll take it to our marvelous engineer David Brundle and he will machine it down to a beautiful cylinder 55 millimeters long and 35 millimeters in diameter and then it will go to America to a periodic table

  1. a mask like in the movie the collection , i have a balck onix stone has anyone melted that with pearls wonder what it would turn out like

  2. this is so cool, i love that dude job making periodic real periodic table elements, thou i wonder how dangerous to make the other ones or atleast try to get them in a bottle,

  3. Awesome!

    Kinda want to see how badly damaged somebodies hand would be from just a single drop of that stuff touching their hand now. Morbid I know. lol

    What I'm really interested in though is where I can find furnaces like that to cook metal and casting molds to make sinkers and stuff.

  4. Would you like to hear an idea? We need to inspire the next generations to explore space. Asteroids in the asteroid belt are made of elements. there is most likely a couple hundred million of asteroids made out of pure gold, or carbon with centers of diamond, so if we have a practical way to get out there and back, we can progress by tenfold in the future.

  5. I tend to wear a welding visor when pouring out molten metals into a mould, along with a welders apron. If you incorrectly heat the mould, molten metal causes it to jump due to rapid thermal expansion, potentially giving you a molten metal shower.

  6. the um speak is strong with this one…painful to watch, seriously people. master your speech.  i mean, i'm not flawless grammar master either, but at least i don't just blurt out useless information every 3 seconds.

  7. hi, im a new jewelry maker and i dont understand the logic behind alloys. looks like silver 925 (with copper) melt at 800 deg even tough both metal have higher melting point. the fact that it's an alloy reduce its melting point? so if im right, i could take pure silver, add cooper and it would melt below 900 deg? Is it the same for all metals alloys like if i'd mix gold and silver?

  8. So they make actual tables. how to they display the radioactive isotopes? and also how to they display the Elements that only exist for short periods of time?

  9. a very wealthy individual who appreciates the periodic table that much is worthy of their wealth. I approve , lol. like it matters 😉

  10. I want a cylinder of silver! I'm not interested in selling it to make money or whatever. It's just so cool looking and shiny!

  11. A motorbike helmet and gardening gloves (I bought an identical pair at my local DIY shop for about £3). I see no expense is spared in ensuring safety is number one priority (to steal the catchphrase of another well-known YouTuber).

  12. A thousand Pounds in 2011, down to 270 only about four years later.
    And yet, before it crashed there were lots of people who were buying under the belief it would continue to soar. Some folks were confidently "forecasting" a peak of 4000 British Pounds per kilo. Some people timed it right and made a tidy profit. Many more folks got soaked.

  13. You truly realise this must be a true British movie when he comes up with the risk assessment xD
    Only in Great Britain, where even tiny risks can be made great again!

  14. Notice how that silver cylinder didn't have any tarnish or anything on it? Pure silver does not tarnish readily with anything other than hypochlorite, ozone, and sulfides. It also does not combine with oxygen at any temperature whatsoever. The characteristic dark color most Jewelers see comes from the 7.5% copper added to it.

  15. These cats doing risk assessments and donning great to melt metal…..
    Average youtube wannabe in shorts, sandals and using furnace made of trash.

  16. I would love to ask if they have two types the gold cylinder available in their displays, one of pure gold, and one with a lesser metal core surrounded by a decent amount of gold which is much cheaper. I would also like to know what purity of gold they use.

  17. Great job! Amazing to see gold and silver to made into these large cylinders! Besides gold and silver, what other metals, especially precious metals, that have been made into this kind of large cylinders?

  18. I cant be the only person who thinks just making a solid cylinder of any high priced anything to put on display is a severe waste of resources
