- Part 1: • Silver Tree, Part 1
The second part in my Silver Tree experiment. Here, I collect the silver produced in Part 1 and melt it down into a bead using my brand new mini propane furnace.
This furnace, and all the accessories you see (except the torch), is made by a guy on eBay named canvasman34. He's got lots of great metalworking products and I'm very happy with my purchases from him. Here's a link to his store: stores.ebay.com...
6:47 the reflection on the silver looks like an eye looking back at you
that was a great demonstration. I really enjoyed it. Some advice for you..... when you remove your melt, you still have to keep the torch on the crucible for the pour. the metal immediately starts to cool when removed from the heat source. and actually you don't need the the furnace for a small amount. torch straight to the crucible will do it. holding it with tongs, not sitting on firebrick. great video . thanks for that.
That's the coolest part of the experience to me the result after the reaction is finished!
Thanks! I like to show a little more than just the demo in most videos, like disposal or other extra steps, so people get a sense of what hobby chemistry is really like.
What i do is i put scrap metals into a small crucible on a myca board and heat it up with an Oxy-Propane mix, it melts VERY quickly and as its molten i sprinkle borax onto it, let it cool (not completly, just to the point where you can pick it up) and drop it in an acid solution that wouldn't affect the metal but would dissolve impurities.
On another note, i have a crucible for each metal as i would not want a 99% 24 carat gold pour to be ruined by left over silver in the crucible.
Yay, fake white gold.
I know I'm late to the party but this was pretty cool! Personally Chemistry is my favorite science topic and I can't wait until I'm able to take it as a full out class in High School :3
I liked chemsitry until I actually took the class. good luck
Kevin O 3 years ago.... you taking chem now?
Wonderful stuff this. Takes me back to high school Chemistry and the wonder of it all.
Maybe a go at making a Bismuth "egg" might be a good use for your new forge. From what I've seen you melt down the Bismuth and cool it slightly and poke a small hole in it to reveal the crystal structure forming. Basically a Bismuth geode! Would also love to see that bismuth extracted from.. oh IDK Pepto Bismol?...
I haven't made an egg, but I've made lots of bismuth crystals - check my blog! I've also tried extracting Bi from Pepto Bismol, but it turns out it's very hard to melt the resulting powder into a metal bead. It prefers to oxidize to yellow bismuth oxide instead. I tried a few things to get around that but was never very successful. If I figure it out I'll certainly make a video!
So then you dissolve that in HNO3 and do the whole demonstration over again, right?
It would be interesting though to see how many times you could repeat the demonstration, silver collection and melting etc... before the losses accumulate and you're left with no more silver.
Yep! Redissolving and using cleaner copper would help with purity too by reducing that copper oxide buildup, I think.
Yeah definitely. You could probably also etch the surface of the copper with dilute HNO3 to clean off any copper oxides and sulfides.
Oh and I will be posting a "Happy New Year" video at 12:01 so make sure to check that out.
HI
Nice furnace! Enjoyed your video and looking forward to new experiments.
Dr.K.
Thanks very much! There's a link to the person I bought it from in the description, if anyone is interested in buying their own.
if you want bead in the end make a small indent in a wood piece and pour the molten silver in it.
I've seen that done, too. Usually a very hard wood is used; correct?
John Ratko
it is not that important, when you pour the molten metal (in such small quantities) the surface of the indent transforms into coal which doesnt conduct heat and it is hard so even if you use a soft wood it will be ok. the important thing is the wood should be dry because if dump the molten metal will splatter.
Hobypyrocom I see.
Really nice series, thank you for uploading. What was the final mass of the silver?
I think and this is only a theory but instead of pouring the silver in the water you should've just let it cool down and when it becomes solid then get it the water cuz it was in a sphere like shape in the crucible not a critic just an idea
The red may also be surface pitting of the copper. Probably the oxide though!
Gnarly! You should make Christmas ornaments out of this stuff!
I would think that possibly the copper oxide was a product of the silver nitrate being a bit decayed (as it was stated the powder was a bit grey in the first video)
Agno3 + h20 + cu = Ago + Cu(NO3)2 + H2, so it's not pure silver but silveroxide
The oxidation on the Cu wire is your problem. Just clean the wire next time.
did the mass of the copper wire decrease after the reaction?
put the torch at an angle so the flame touches the whole crucible. it just heats it up faster
This whole melting thing would go a lot faster if you used that other hole for your blower... like a hair dryer... also use table salt before taking your crucible out, it's
better than borax and takes the contaminates out. Also when you're pouring your
molten into anything make sure you do a steady even pour and all at once, don't
do a little bit at a time.
I'm not sure if you take suggestions, but it'd be great if you do a video on the "blue bottle" and "chemical traffic light" experiments.
I actually do both of those all the time for science educational outreach! If I can get the chemicals at home that'd be worth making a video about for sure.
mrhomescientist Good to hear that!
i got that same possible copper(I) oxide on the copper, but instead of doing the silver tree experiment, instead i made copper(II)acetate, but it is probably the same oxide
Nice job! I love your videos!
thank you dear friend so much also did you know how do tree gold. please teaching us
So how do you seperat the silver from the water do you pour the water though the coffee filter
Copper wears out quickly and needs to be replaced offen.
It would be really nice to see crystals of copper on an iron wire, or gold on a silver wire.
+Connor Steppie Copper tends to plate out rather than form crystals, for whatever reason. Gold I imagine would be similar, but I'm not sure!
mrhomescientist always worth a try!
From past experience, copper tends to form the ugly, clustered crystals like the late stages of the crystal tree.
+Connor Steppie How were you able to grow copper crystals?
I've also seen tin crystals grown electrolytically, definitely something I want to try.
mrhomescientist Simply by letting an iron paperclip lie in copper sulfate for a day or a bit. It kinda looks like a thick crust of copper.
Also, thebackyardscientist grew some pretty nice copper crystals with electrolysis
is this stuff profitable? let's say you wanna make silver in massive amount???
he's not making silver, he's extracting it from a solution that it's already contains silver. that's like asking if it would be profitable to strain the gold flakes out of goldshclager.
I just watch you melt metals into ingots I've looked for someone who achually does it for ages can you do a set up video I have no clue how to make a furnace or any equipment I would need to do things like this it would really help if you do thanks!
The Zebra Millatary Well I bought the furnace in this video. Check the description for a link!
would it be possible to make aprince rupert's drop out of metal? Or is that a glass only thing.
Great question! I don't think that's possible. Prince Rupert's Drops work because the outside of the glass is cooled rapidly while the inside cools much more slowly. This causes tremendous tension that makes them very strong (except for the tail). With metal being much more thermally conductive and less prone to contraction on cooling, I don't think the conditions would be right to form a Drop. Plus molten metal is far less viscous than molten glass, so you couldn't really draw it out to form the long tail.
Could it also be possible that the red copper oxide could be resulting from the degradation products within the silver nitrate crystals?
Not quite sure what you mean here.
mrhomescientist You mentioned that likely photoreactivity issues with the AgNO3 had caused the crystals to turn grey. I was just wondering if the chemical changes that caused the color to turn could've had anything to do with the unexpected results.
John Ratko Ah, well it decomposes into silver metal, oxygen, and nitrogen dioxide. The latter two being gases, I'd think they would have mostly escaped by the time I used it. I suppose it's possible the remaining NO2 dissolved to make nitric acid, but this would be pretty negligible.
what are those plastic sample trays called ?
They are weigh boats. Very handy items!
And can you clean a crucible like in this video were it got stuck to the side
The Zebra Millatary Not sure how! It'd probably require just heating it up again with more borax, though.
Were there shoes worn whilst making this video? Just asking ;)
Hey I was one of your students at Stem camp in PC you need to upload more ;-;
Cardenal Collins Yeah I do. I've been busy lately, but I have no shortage of ideas. So I hope I can get back in the lab soon. Hope you had fun at the camp!
Can you please make a video about how to make elephant toothpaste
Which is the limiting reagent? The copper or AgNO3? What if you didn't use up all of copper-would it be the excess?
Silver nitrate is limiting and copper is excess, yes. There's tons of copper available; it's a relatively small surface area though, so the reaction takes quite a while to complete. I designed this experiment that way to ensure I didn't lose any silver.
Thanks for the valuable content (and reply ;)). Great quality for chem
@@ihmintz Thank you for watching!
Looks like you paid a little under $20 for your 10 grams of silver nitrate. Ten grams of AgNO3 should potentially yield approximately 6.25 grams of silver; correct? Looks like an ounce of silver at this moment of writing is worth $15.76USD OZ. Assuming that's Troy Ounces; "One troy ounce (oz t) is equal to 31.1034768 grams" [source: Wikipedia]. Well, I'll just have to keep looking for my free -gold- silver mine!
Yeah by your numbers that works out to a little over $3 in silver. No free lunches!
mrhomescientist Nope, none at all.
Does lead iodide have any uses?
Is it silver
What is the dark bead in the middle of the silver at 6:40?
That's just some reflections from the shiny molten silver!
Oh okay.
Make new videos and do more gold panning and things with your furnace
Just an idea on ur next vid possibly-----) could you make graphene? :) thanks!
Ahm! Miracle!
is There an alternative fir borax? Borax is prohibited in Germany.
+wayne train Why? It's a completely harmless cleaning agent. That makes no sense to regulate it. I haven't heard of alternatives but I'm sure if you search for fluxes that would point you in the right direction.
+mrhomescientist They say That its carzinogen.
Why do you no longer post videos. I can see that you still like chemistry(science madness).
Yeah I'm still definitely interested, just haven't had a lot of time for chemistry lately. Lots of other stuff is fighting for my attention! I haven't stopped yet, so expect more videos in the future (I'm just not sure when).
Where do you get those gloves
White Wolf The welding gloves? Home depot, or a welding supply shop.
+mr home chemist why dont you make videos anymore :'(
+Seth Black Oh I'm around still, just haven't had much time lately :( I do plan to start up again some day.
hope u get back soon. i enjoy your videos
+mrhomescientist Can you give an ETA on a new video if everything were to go smoothly(I apologize if I sound impatient)?
+Elyjah Vasquez Well I'm currently looking at a new video camera, and I have an idea for a new series of videos I'm excited about. So who knows! I don't want to back myself into a corner by giving an exact date :) But maybe around the end of the month?
+mrhomescientist thats cool yo
what silver is it ?? 925 or 999
I've never tested it, but it should be extremely pure. .999 easy, I would say.
Where u at
If someone would make this with bigger scale would you earn money
No, unless you can get the materials for free. Same as with gold refining. Fun experiments, but don't expect to make a business out of it.
Upload more vids!
Do you still make videos? I hope you do
+Jeff and team One of these days. I've been busy with other things lately unfortunately.
+mrhomescientist but will you still make videos every once and a while
+Jeff and team Oh yeah I definitely intend to. My interests lately have gone more towards geology strangely enough, so maybe a video on that subject!
mrhomescientist weird i was into geology it was actually the first science i got into, i still love geology but now i also like chemistry. I would love it if you made a geology video, because i like both geology and chemistry
+mrhomescientist why are you not making videos
Remake the copper video
Here, have a subscribe.
eray lülecioglu Why thank you!
Now make Methamphetamine
Why can I not find a cute 20 year old who would like to do this with me?
first
ps:sorry >_
MEDIOCRE! 4/5
