You Sir are a modern day Alchemist!! I’ve been a huge fan of yours for a long time. I look forward to seeing what you release for us to watch.

very elegant example of clean precise chemistry. Thanks as always!

That pour was a work of art, a master craftsman.

Superb ! Love the way you just do these things as if you're just changing a tyre ;) The rate of Cl2 gas bubbles looks really high - it might go faster in a column rather than a beaker, with a slower gas rate, with the gas hitting more of the metal as it rises. With a column, you could also duct away the waste chlorine gas into a jar of caustic soda solution to neutralize the waste gas. Chances are that a UV light would also help in there. The UV would help the Chlorine gas to split and whack the gold quicker.

That was a really awesome experiment! I was a little worried at first, but that second batch was amazing! Great video!

I did a similar experiment a couple of years ago. I spent a lot of time dissolving a gram of gold powder. Then I found my mistake, corrected it and dissolved the gold with less chlorine used. You gave me an idea for a new video 🙂

That was probably the best looking gold bar yet! Keep the videos coming!

The loaves are getting more and more consistently perfect.

Your videos never cease to amaze me every time. You are an amazing teacher my friend .👏👏👏

Beautiful bar! Really enjoying all the different methods you have been demonstrating lately. Fascinating stuff.

I have very little comprehension of the processes involved in the chemistry voodoo you perform, but I love to watch the magic.

Love the chlorine gas dissolve videos. Next you need to precipitate with SO2. Always love watching that.

3rd person title and chlorine gas?!? Sign me up! That bar is absolutely brilliant. No film, looks perfect.

Pure(r) enjoyment! Thank you Sir!👍👍🤟

Oh Sreetips, I love the content but you know the old saying, "refine it more than twice, and you're just playing with it" 😆

Brilliant science tutorial involving our favourite metal! Cheers pal ✊

Interesting video Streetips thank you! Chlorine dissolution takes some hours but you don't have to deal with excess nitric acid. I guess the end result is also "cleaner", with less impurities?

I goofed. The bottom of the 2,500 ml beaker had a white residue on the bottom of the glass. I've got that light brown parcipitate all the way to the bottom of the beaker! Unbelievable!

Beautifully done! Start to finish!

Great video, sreetips. I like this method seems to a whole lot clearer and as always another beautiful gold bar

He gives a thumbs up.

I can't help but feeling that a lot of the chlorine gas went up out of the fume hood without reacting with any gold at all (although it may have corroded the fan). If you were doing this on a large scale then it would probably be worthwhile to capture the gas and cycle it back into the process.

Excellent video, try find an all glass co2 diffuser for fish tanks, that way you can go faster gas-wise without the losses

Such a beautiful ingot and the dissolving the gold with chlorine gas was fascinating. 👍

Wow, just Wow! It is fascinating to observe the many ways you know of extracting gold. Each one produces some of the coolest bars on the internet. Thanks for sharing your gift of perfection in refining metals.

Wow that second batch of gas totally went ape on the gold. That was awesome sreetips!

Nice work, as always....Thanks for sharing with us.

Great vid MrSreetips Always a good looking reaction.👍🔥

Sir just like Trump knocking it out of the ballpark during CNN TOWN HALL you knock it out of the park with every video another great video of real science

Perfect timing for a sreetips.. but then again...when isn't 😊

Nicely done. Atomization of alloyed gold and chlorination of hydrochloric acid is desirable because the gaseous emissions are easily scrubbed and abated. You chlorinated with gas and it's also possible to use perchlorate directly in the reactor instead but clearly the use of gaseous chlorine as the oxidizer is cleaner, resulting in a quick dissolution and fewer contaminants.

2👍's up sreetips thank you for sharing

the fact that only a gas has been added to dissolve gold would probably lower even further any risks of contamination, it's a great idea! I wonder though if it would be possible to cycle the chlorine produced back again into the beaker, because i expect alot of chlorine is being is lost in the air

Awesome video! Would you make a video on some odd gold alloys? Like purple gold(aluminum gold alloy), blue gold( gallium or indium gold), it would be interesting to see.

Great work sir

I never get tired of watching your stuff. Looks like you love gold more than Goldfinger did. You are really obsessed from gold.

Tips, can we get a small batch with lead in it? We would like to see the sulfuric precipitate lead out

Gooood afternoon from central Florida! Hope everyone has a great afternoon!

I had a nice watch like your Omega got it cheap because of the wear on the lens, buffed it super carefully using a glass scratch-removing compound on cotton pads on a dremel and it came up like new

This will be the cleanest gold on the planet. No pun intended.

I wonder if you could've put the gold foil in a nut / coffee bean grinder to break it down more. The stir bar was really laboring to get er done. You could probably put the Chlorine tabs. in there separately as well.

Better than watching p.rn ^^ Crazy how gold can stimulate our brains, made in super novaes only for our pleasure! MAGIC!!!

You never cease to amaze.

Such elegant, pure method of gold dissolving! But definitely, you waste a lot of chemicals and chlorine, the rate of gas production for such reactions should be such, that bubbles coming from tube dissolve and disappear before floating to the top of the solution. I remember someone in the past who wrote a comment about using a big flask filled only to 1/4-1/3 for this, bubbling to the moment all air is displaced from the flask by chlorine, and then stop generation and stirring to the moment chlorine is used up. An alternative could be a tall and narrow vessel, so gas needs to bubble through more mixture and gets more absorption and reaction time. I hoped only that at the end you will precipitate gold with SO2, making it full gas workup XD

That's a $3000.00 bar of gold

They are called transitional errors they are hard to find theirs only about 20 of them

Another excellent video! Thank you!

Hello Mrs and Mr sreetips. I love this clip sir Thank you😊 Arne

Bleh, i was hoping that when you dissolved the Gold with gas, that you would bring it back with gas. Nope, stump out. Fun one, ty for taking us along

I think that the aqua regia make a better drop this one barely turned black excellent video awesome experiment thank you for sharing this six stars

I dig those video so much. More please

Always a thumbs up for your videos.

Chlorine is a nasty, reactive chemical. I love how it rips out Au ions from solid gold like it's nothing special. :) I like the water gas trap you have there. That's a nice precaution.

To me it always looks like the rinse at the end could be a little less "rushed" to prevent the amount of gold washed into the waste container. I know you don't rush and the waste is refined aswell in time.

He thoroughly enjoyed this video

I have been watching your content a long time and I'm still today I find it just as fascinating today as I did the 1st time I watched years ago my kids and wife enjoy your content just as much with that said I would love to have a piece of Sreetips memorabilia no precious metal or anything but perhaps a piece of used "waste" like a "fingers board" you processed with your stamp on it or anything like that we don't have a lot of $ these days due to the whole made up medical stuff going on past few years but could pay shipping or whatever if possible if not it's ok my friend just keep on doing what ya doing you have some of the best content on KZfaq for sure you in the top 2% of quality content on the entire channel. From East Tennessee we hope you and yours have a wonderful day.

Nevermind you answered it later in the video. Thanks

Awesome video and nice gold bar thanks for sharing sreetips

I think i missed something. How did 37 g of gold powder and 11 g of gold ribbon which is 48 g make over 48 g? You were expecting more. Plus not all of it dissolved.

Next time you need some gas for dissolving something, give me a call. Prepare a pot of chili, give me 20 minutes and i'll produce some highly toxic and corrosive gas for you (for free 😁). Thank you for your great videos! I ❤watching sreetips!

Amazing video Sir … there is always something new to learn in each video

Enjoyed the video, thanks!

Are you loosing much Cl2 out the top of the reaction beaker? Might be worth giving the bubbles more time/surface area to dissolve.

Hey Sreetips, I wonder if a gas dispersion tube would help diffusion of the chloeine gas allowing faster and more thorough breakdown of the gold.

You forgot the stannous my man 😂

20:52 brought taco bell to mind. Neat video, interesting process.

Love to see more gold ribbon dissolved maybe in aqua regia

I wonder if a flat glass plate with small holes in it, in the beaker, with the gold on top of it and the bubble tube underneath, would give you better contact surface area

I remember in one of your past videos, you dissolved the SMB in water, filtered it, then precipitated the gold with the solution. I thought it gave great results, I was wondering why you don't use that process each time? It seems to me like it would never be a bad idea to filter/purify a chemical powder that is meant to be thrown on a tree stump, in case the manufacturer wasn't as careful as they should be.

Do the tablets have more free Chlorine than the already powdered stuff for pools or the powdered stuff not available in your area?

While I like that it saved on rinsing in the end, seemed like it took more effort up front with the gas generation. Had me a little worried it wasn't going to work in the beggining!

Would like to see a case where lead actually comes out

I'm pretty sure they sell powdered chlorine instead of tablets. I know because I used to make my own reactions back in high school.

What is the mechanism involved here compared to aqua regia? Merely increasing the concentration of Cl- ions such that they attack the gold? Also RE: efficiency, I suspect something like the chamber process could be used. Put just enough distilled water in with the gold (no HCl), then fill the chamber with an excess of Cl2, seal it and wait.

Love that poured shiny

Thank you for all of the very interesting videos. The city water that we have is fairly hard and actually contains grit from the city wells. Are you using a purified water to make the ice? The stump remover used to precipitate the gold at the end, any concerns related to impurities getting into the gold? Just trying to understand which aspects are important or not. Thanks

Great video Sreetips! Just one question though. Did you " grease " the addition funnel with HCL at the joint before adding it to the beaker? I've seen many professional chemists lubricate joints with the relative solutions that they're working with ( ie - HCL when using HCL, H2SO4 when using H2SO4 ) in order to make a good air tight seal.

LOVE your videos man keep it up! where can I find your eBay?

@6:50 Could you use an upside-down glass funnel in the beaker to increase the liquid-gas surface area and the contact time of the chlorine gas ? THX.

Getting good at pouring those bars.

Is it possible to make a gold cell set up, same as a silver cell ?

Besides not having the nitric acid in the solution, are there any other benefits from processing the gold using this method? I enjoyed the experiment, but I can imagine chlorine gas is rather dangerous to work with if not careful.

Woow🎉🎉🎉🎉🎉🎉🎉234k melbers😊. Come on folks.....

I see you use a different Watch glass , What is it called? . I wonder if Mixing HCL with Clorox if I could generate more Chlorine gas

Have you ever made a video or performed any experiments for gold recovery with gold plated alloy 25 electrical contacts/pins? (Biryilium copper)

Would be cool to see some rolling action. Awesome if you got a punching and stamping machine

Could you use the electro method to for plated goal?

Im guessing by setting your hot beaker in a dish keeps the breaker from cracking

The master 🙌 😂❤

That’s a beauty

Cool stuff Sreetips.

I watch all your videos and i always have a question in my head. it might be a stupid question but it drives me crazy. You ended up here with 48grams of gold at the end. how much however does the gold powder weigh if its dried and before its melted? Also and this one really gets me. when you have the gold solution dissolved completely sat in approx. 500ml of solution lets say. Does that 500ml of liquid in that container weigh 48grams more than an identical container just with 500ml of liquid and with no gold dissolved solution ? like i say might be really stupid but it drives me crazy thinking about it

Any Book recommendations to help learn the process of refining precious metals

Bravo 👏 👏 👏

Wasting most of the gas. Vessel should be enclosed and put on a shaker.

Chlorine Gas Oh Man that stuff is Dangerous. Please be care full.

Nice 👍

When u going to do that old stock pot video my man 💪

Im surprised you didn't use any heat to spead up the reaction

Sreetips your a genius but where do you get all your bulk gold also you need to start a gofundme to build a bigger lab I will chip in
