The one off the back, but there was also a small chunk near the front bottom corner. Then you could see all the gold drops along the sides of the melt dish. A little borax along the sides and he might get a gram or so out of that melt dish.

Yes

I’ll get it and add to my next batch of karat gold - no worries.

I was just thinking, “There’s $30 just sitting on the brick…”

Ya I was wondering about that 🤔 lol

Thank you!

@@sreetips Pls help i need advice..Im new at this but was fasinated by few vids back you growing the silver and im a rookie and wanna start doing the same so equipment wise looks like your using a laboratory power supply found one on ebay is a maximum of 30V 10A DC Power Supply Adjustable 4 Digit Display Laboratory Power Supply..Also you said you were using nitric acid but what percentage is that?..Because the ones i can find online is rated at 68% so will that be suitable and what outher acid where you using might have been sulphuric also what percentage?..Im a total rookie at this but really wanna learn but not die in the process anything you can tell me chemicals percentages would be awesome..Looks like it uses a really small amount of electricity as well for being left on 24/7 so i can't see it hurting the power bill too much as well..We all gotta start somewhere and just in the learning stage appreciate any help thanks

Thank you!

came here to see if it was just me - thanks

Your answer its in the fist video this serie.

haha, same. Also, this is my first time bother to read any comments on a sreetips video. Sree's got a high booty bot ratio.

Yep, I'd guess a 1 to 2g chunk of powder. There was also a smaller piece that fell off to the left in the last batch he put in the dish.

@@menotume and a few beads around the sides of the melt dish

He won't do that. He avoids those details to protect the system that he and his wife have of acquiring the material they refine for themselves.

I’ve tried to convince Mrs sreetips to let me shoot video of her in action. But she refuses because it very cut throat. And I must respect her wishes

And good evening from just north of London.

Goooood evening!

@@essexfarmer9610 howdy! 👋

And from south Florida

My dear friend...hello🙂🔥 God bless yoy🙂

I noticed that.

@@sreetips never mind, I'll delete my own comment...

Adding the note here now... @sreetips since it smelled like wood I am going to guess it was sulfur dichloride. Was there briefly a cherry red liquid? No, I did not see that since it was dry enough so that makes the allotrope a whitish gas and pungent like burning wood! Bingo! That is what it was, not trapped H2O in the powder gold at all. I stand corrected from my earlier comment of it being just traped H2O. It was trapped SCL2 (g). That is a nasty gas, would have been better to have your respirator on you old salt dog! It forms chlorine containing acids on contact with your damp mucous membranes and as a red liquid rather than a whitish gas is highly corrosive and toxic. As a gas it did little harm if you rinse your nose and mouth with 1/2 normal saline and an infant nose syringe made of soft rubber or now a days silicone -if not done you will have a bit of membrane peel and that would be the extent of it over the few times you were exposed, take care in the future to pulverize any gold sponge better while drying please or use a respirator as you have in the past. That explains the thick whitish gas discharged several times, make a note in the book so someone else reading it will be warned as well. Folks, all is well, this (gas precipitation) is the best method, still, it was a lesson for ALL. That is a great camera and lighting when I went back and looked it is just as I have heard it described by and in my uncle's crabby hand written notes.

I didn’t see and red liquid.

@@sreetips as was said in the comment where I was talking out loud to a dragon naturally speaking app... I too did not see any red liquid so it was a gas form of the compound...

i think the hydrogen proxied gas precipitation makes the cleanest. that i have seen you do so far.

H2O2 dissolve, SO2 gas precipitation. A good combination for pristine GOLD.

Thank you

I’ve found that the key is getting that graphite mold real hot.

Let me tell you, I’ve experienced some spills recently, not much, but in refining every little bit counts. These never would have happened if that pesky camera wasn’t in my way all the time.

Thank you

It was all 800 parts per thousand silver flatware.

He was relocating some of the gold during rinsing and pour offs into the waste refining stock pots, eventually that will be recovered, but to me that is a waste of time and resources if you've already got the gold nearly pure to pour it off into a lesser pure mix then means you are wasting that effort. Instead to pour it off into one dedicated container to let it settle out and then after it has settled out you could pour that solution off, but i think that would be a good base to see if you could work with just that solution to get the gold out without recontaminating it with other metals. I'm not sure how that would go, but perhaps some aquaregia and then an SO2 bubble precipitate... Also I've already mentioned that he's wasting a fair amount of nitric acid in later boils and rinses that could be reused for his initial acid boils. Pouring that into a silver stock pot loaded with sterling silver is a big waste of time and effort because later he's having to reprocess the silver out of those solutions again. Getting huge buckets of cemented silver to then reprocess again to remove the copper and other metals. Just adding extra work for himself. Sorry to harp on this, but I think it important to be efficient with time and resources. :) And sure if you are happy with what you are getting than you can easily ignore my thoughts, but for others who are reading along I think it worth to think about. I think of it this way, when working on a project I don't want to introduce more Gremlins by making it more of a mess. In gardening this means weeding from the uphill and upwind areas (energy and time flows and edges are important). In metal refining it means not doing things that push your results backwards towards the other contaminants if you can help it.

Excellent, thank you

Waste treatment is easy and cheap.

There’s a way to grow high purity gold crystals. But it’s complex and requires special apparatus. I can grow pure four nines gold in my electrolytic gold cell. But the gold doesn’t look the same as the silver crystal does. It’s more nodular. But still beautiful in its own rite.

Thank Netherlands.

I’ve never tried it.

A large mason jar full would be cooler lol 👍

This is gold refining, pure and simple.

To be honest, mine is the only one I watch.

@@sreetips gotcha thank you Sir

Stump out is easy and cheap but the gold will have salts in it. The SO2 gas is a little more time to set up and take down, but the gold is very clean.

I had an extra light shining on it

Waste treatment.

I’ve got a bucket full of filters that I need to process. I’ve done them in the past. Now they’re due again.

New word for the day, denouement: the final part of a play, movie, or narrative in which the strands of the plot are drawn together and matters are explained or resolved

@@sreetips 😜 It was your closing third act. 😂

I always learn new things by reading the comments. Answering question (if I know an answer),is the best part of the experience. I get good tips and ideas

I accumulated it over the last 14 years. When I thought of an experiment I’d figure out what glassware I needed, then went on eBay and ordered it. I had a small chemistry setup in my basement when I was about ten or twelve. But I abandoned it when I got in high school and discovered partying and girls. My current setup is a continuation of that time. Only now I can afford nicer stuff to practice with.

It’s finally here! Enjoy those warm sunny days Arne.

Thank you my friend..And same to you Sir ❤️

Sounds like your flame isn’t getting hot enough.

Thank you and welcome!

Yes - purple is the color of colloidal gold.

@@sreetips maybe that could also account for the missing ten grams, between that and the two chunks that fell out of the dish I mean.

Unfortunately I only work with gold and silver. No experience with dead cell phone lithium batteries.

Yes, but there is stuff out there that can deceive. After viewing thousands of pieces of karat gold over the years, I can spot fake stuff just by looking. But every now and then some junk can and will find its way into my melt dish.

None that report in an assay. The gold comes back three nines - every time.

@@sreetips Really impressive that some home chemistry with careful technique yields such a great result!

The poison cloud gets exhausted outside away from my work area. You wouldn’t work on your car and in a closed garage with the motor running, would you? The poison cloud from the cars exhaust would concentrate and kill you. And the exhaust from an automobile is far more harmful to the atmosphere than my occasional chemistry experiments.

Powder

I should have noted it in the video. I knew that there would be many comments about that and the other crumbs that escaped.

Stock pots are due

I’ve no experience with gold plating solutions. But if it were mine, I’d cut the cardboard with the gold plating solution out, burn it to an ash in a melt dish, place the ash in a clean beaker and try a little Aqua Regia to see if I could detect and gold in the solution.

Those were tenths only. Not enough to make up ten gram loss. Some of the karat scrap was probably fake. Fake stuff does get by me from time to time.

No, some compound from gas reaction. It smelled like burning wood.

MAP torch to heat the mold. Oxy/acetylene with a cutting head for the gold melt.

@@sreetips Thank you Sir!

Waste treatment.

@@sreetips that would be an additional cost per gallon am I right and would also depend on what chemicals

It’s all pretty much the same process. Cement out the precious metals on copper in the stock pot, transfer the copper nitrate from that to the bucket full of angle iron to cement out the copper. Then all I have is an acidic iron solution. Add NaOH to pH9 to drop metal hydroxides, filter out the metal hydroxides, raise filtrate to pH7 (almost drinkable) then add to the normal waste stream. Nothing acidic or harmful gets poured down the drain or in the toilet.

@@sreetips at that point then it's safe for the drain. I'm almost at the point of trying this process just working on the beakers and molds. I've been collecting sterling silverware and a bunch of other stuff for silver shots. Just want to make sure I get it all down right but I'm sure I'll be making a few mistakes along the way

It smelled like burning wood.

I use hydrochloric acid 31.45% nitric acid 68% to 70% and sulfuric acid (Rooto Professional Drain Opener) 93%
