Bigstack is how I found sreetips so I love when I see people mention him. No surprise there's a lot of overlap in their fanbases, even if their methods and materials aren't the same.
I love that you show all of your processes. It would be easy to just show the successes and none of the set backs but you always seem to show where things go wrong and I love that. Thank you.
The crucibles cracking was a bummer. I leave a gap between the fire bricks wider than half the crucible and position a weeding torch to engulf the entire bottom in flame. It reduces the thermal energy required from the top and keeps temperatures more even from inside versus outside the dish. All that silver represents a lot of refined gold, very impressive work!
Bravo Mr Tips, bravo sir. I always knew you would keep your floor and bench sweeps but I liked the way you recover the metals in them. A very simple but efficient process.
Allways a pleasure to see your videos. This time, I dont know how much silver recovered with a spoon of ash, but you lost a lot with that craked cricible, in my opinion... You must have a strong hart.
Good evening Sreetips, 37.4lbs...L0L. Just pouring 6 or 7lbs of cement silver is enough of a pain in the butt. 37.4lbs is an undertaking in itself. I'd personally would like to see you melt the low grade sweeps next time in the last melt just to see what you ended up with. Experiment idea: Your silver shot is extremely contaminated compared to what I see when I processing my own pounds silver shot. I was wonder as an experiment if you were to put your contaminated silver shot back into solution and re-cement it out on copper. To then re-melt it back into silver shot. Would it clean it up leaving contaminants behind instead of in a $10 filter which is soon to be going up in price? That left over solution could then go into the Stock Pot to recovered any precious metals still floating around to be processed at a later date. Just an off key interesting video idea I would be interested in seeing. I'm sure the TH-cam views will be well worth the nitric acid costs. Could be something extra that could be done in the background of the next silver cell series. Best wishes and have a wonderful Thanksgiving Mr & Mrs Sreetips.
Thermal shock is annoying. Silicon Carbide is tougher in that regard. Or maybe if you used two melt dishes (or crucibles) one after the other. Let one cool slowly and use then the next. Followed by the previous one now that it has cooled down, and so on. This way there is no thermal shock between the large cold mass of silver and the hot ceramic. You could go all day that way.
I'm curious why not use something like a crucible and electric furnace or even gas powered? Seems like it would be a bit easier to manage than a melt dish
Sometimes Im glad to not have the means or space to do something like this, but I do enjoy watching you doing it safely and not hiding anything when it comes to failures.
Things always seem to happen just as you are about to pour. My own furnace mishap a while back also was at that point. Like the universe is purposefully picking the most dangerous few seconds for stuff to happen XD. Glad to know you're OK and the metal didn't cause injuries! Always use PPE, folks.
Perhaps get a 55gal steel drum to replace the pot setup and even ditch the board. The height of a full drum of cold water should be enough to solidify it before it hits the bottom. You could then run 5+ lb crucibles out of the big propane furnace.
You are welcome. It looks like the crucibles performed admirably. Being that the mass of that cup of silver is 10.5 times compared to a cup of coffee that’s a lot of weight for that heavily cycled vessel to haul around. Better for it to break there rather than going into the drink. Looking forward to seeing the shot become shards! Thank you Sir!👍👍🤟
put the heat source shooting straight down in the center, dont try to rush it with the handheld torch. i think it causes the crucible lattice to warp and fracture when one part gets hotter or cooler as you swirl the mixture
I had a good chuckle when I saw that big bucket of silver and little dirty melt dish you intended to use. A modest gas furnace and crucible would seem sensible at that point.
I’ve come to dislike processing the silver from my gold refining. And so I’ve let it build up. I need to get it moving or else I’ll run out of time, on earth.
That's a wicked cool color coming off that new crucible after the yellow one broke. It's like in. stuff with the Blue Flame coming out of the torch and hit that crucible must be like a bunch of copper and stuff in it that burns off. It reminds me of that stuff you pour into a fire pit that makes the fire change colors. That's really cool to watch.
Very nice! Love how well u handled busted crucible i didnt handle it as well win my crucible broke with 100g of gold! It was bad day but i eventually got most of it back still missing around 2g tho
With the price of gold being the way it is, I have been selling ALOT of silver paydirt lately. People that pan gold paydirt have begun looking at silver in a whole new light!
Maybe get out the furnace and pour a couple dozen bars instead of making the shot and having to deal with the mess/cleanup that goes along with it? Might be more efficient to grab a bar or two from the stack, lift the anode up and place them right under the anode whenever its needed? I did this in mine and it works quite well given the anode is the same shape as the feeding silver (blank round) and it fits nicely in the :)
Your kind of set up (melting silver powder with blow torch) is for hobby only. When you are doing it on commercial scale, you must have induction melting arrangement. An added advantage of Induction melting is there wont be any invisible silver powder that gets blown away when you use blow torch.
I’m not a professional refiner at the commercial level. I’m just a hobby refiner. I have so much cement silver because I’ve grown to hate processing the silver. As a result, it builds up on me. Don’t get me wrong, I love silver. I just hate processing it. It takes a long time and it’s messy. The pure silver that I produce is for my retirement.
I'm still impressed that you waste nothing, it's all a nice closed loop. We should all strive for that, and yeah a decent sized graphite crucible should work. Not sure if the small furnace can handle it, but give it a go. Pouring it will be a pain, it will be heavy, and you don't want it clumping together. Good luck, I'm interested to see what you come up with. Thanks again!
Hey Mr S why don't you add a kinda speedbump to the slide part of your apparatus like a couple of wires so the silver will stay small thanks love your show
Yeah. You might consider a devil forge. But use a long and slender crucible which will fit down the vent in the top so you can do induction style. I think for these melts, you just had your oxygen level a bit too high on that oxy-ace torch.
Have you considered a stir bar or second pump creating a rotational flow inside the cooling water? It would help prevent the molten metal droplets from sticking together
Thanks for another great video Sreetips😃 Sad that the crucibles broke, lucky you didn't get hurt 🙏🏻. We can call it "shorter interruptions in production due to replacement of consumables😂". /Dennis
I wouldn’t take ten thousand of them. Don’t you know that dollars are worthless? I’d be a fool to trade my highly valuable silver for paper currency. Especially if I didn’t have to.
I wonder if you could make a filter system when you first refined your metals instead of vacuuming the vapor collect it like moonshine because they’re still precious metals In the vapor
Oof, glad you didn't get hurt, that could have been bad! I wonder if they broke because you were dumping the cool powder into a hot crucible? That second one didn't that old, that sucks!
Extremely dangerous!! It’s good that nothing happened to you!! How were you able to come up with so many buckets of cement silver I wonder? This is the most unique channel I’ve ever watched! Hands-down!
I refine gold. I use sterling silver, that I buy at estate sales, to refine the scrap gold. I recover the silver from that, melt into shot, and run it through my silver cell. Silver is a by-product of my gold refining. The cell converts the impure silver (about 980 parts per thousand silver) to high purity four nines fine (9999 parts per ten thousand) pure elemental silver metal. So I’m refining the impure silver, into high purity silver, not creating silver out of thin air. When it’s full, I harvest the pure silver crystal, put it away and forget about it. Then I repeat the whole thing again.
@@sreetips I’ve NEVER… heard or witnessed your line-of-work being performed. It was like seeing a new earth with never seen before human beings! YOU are one of those beings!! Say hi to Paul and Bubba!!! LOL!!
I would love to an update on if you manage to salvage the spilled silver and how you went about it. I'm sure it would be a major PITA to film it, so maybe a community post or story time during your next refining?
For what you are doing, there's a better way to do it. Get a cast-iron mortor and drill small holes in the bottom. Make a steel frame to hold it over the water board. Get it orange red hot and add the silver to it. It will melt and drip onto the water board to make shot.
IIRC, melt dishes and crucibles _are_ considered consumables for work like this - the rapid thermal cycling when in use makes cracks form and spread increasingly quickly.
@@sreetipscould be the cooling from adding more cement silver to a still hot crucible? Might be better to do fewer cycles on a larger crucible, or do sequential melts in different crucibles.
@@sreetips Excellent really cool that you got him at an estate sale. They look very coffee. there. I was going to say they reminded me of my old Red Wing boots. Mine were like a red color. Man, I wore them things until the souls fell off.
Yeah it would be simpler to just BigstackD the whole thing quickly but unfortunately sreetips does not like to use the foundry he finds it very loud and scary for what it is meaning too much can go wrong and he is a simple man with a torch
Get a devil forge and use clay-graphite crucible and melt that stuff fast. You might need a 50 gallon drum to pour the shot into but you could do your pre-processing very fast that way! I suspect this one bucket represents a small percentage of your cement silver so a devil forge is probably well worth the investment since time is an invaluable asset.
My friend, it’s time to get a good size induction forge, drill drill a small hole in the bottom of the crucible, and hang the crucible over your water bucket.
What would happen if you just put the silver powder into your silver cell? Would it not conduct electricity? It seems like your vacuum bag filter would be sufficient to keep the powder isolated from the electrolyte
🤔 How come you have to melt the cement to shot? Could you just pack a custom filter basket with cement. Melting that stuff is a lot of work not that I don't enjoy it on my end.
Thank you brother, I have a question when I melt gold in aqua regia and then I want to destroy the nitric residue by boiling the solution boils but does not smoke nitric acid does not come out, what should be the reason? Thank you for helping me
I evaporate the gold solution down to a syrup until all the red fumes are gone. Then it’s safe to conclude that all the excess nitric has been driven off. Rehydrate with hydrochloric acid.
I wonder if the crucible being very full of cement silver is insulating the bottom of the crucible from the heat that is expanding the sides and that’s what is leading to the crucible cracking. One broken crucible might be a coincidence but two makes me think there’s something going on here.
I think it's time to go BigstackD on that cement silver. Break out the furnace and the what is it #8 crucible? 😅
Cardboard under crucible helps prevent sticking to firebrick!

In my mind a single run of the big propane furnace would be way less risky than repeated heat cycles until failure in little crucibles.
Bravo Mr Tips, bravo sir. I always knew you would keep your floor and bench sweeps but I liked the way you recover the metals in them. A very simple but efficient process.
Well that should keep the beast fed for a few days sir. thank you for sharing this enjoyable video with us six stars sir
@5:00 I still think that if you poured from a bit more height the liquid metal would form more droplets so it wouldn't get stuck together so much.
Allways a pleasure to see your videos.
This time, I dont know how much silver recovered with a spoon of ash, but you lost a lot with that craked cricible, in my opinion...
You must have a strong hart.
Not really lost just more headache to recover
Great video nice silver shot can't to see the start up of the silver cell it always beautiful to see silver crystal thanks for sharing sreetips

I could be mistaken, but I believe he has used a gas furnace a time or two, but is more comfortable this way.

Have you ever tried running the cement silver directly in the silver cell? It might be worth… a shot?
It clogs the filter
Big furnace would definitely be quicker and more efficient
I'll give you $1 for that bucket of cement
I wouldn’t take ten thousand of them. Don’t you know that dollars are worthless? I’d be a fool to trade my highly valuable silver for paper currency. Especially if I didn’t have to.
How quickly will your silver cells eat through that almost 9kg of impure silver shot and what do you think the yield will be?
Should take about two weeks. For every kilo of 98% impure shot I add, I should harvest about 980 grams of high purity silver.
I wonder if you could make a filter system when you first refined your metals instead of vacuuming the vapor collect it like moonshine because they’re still precious metals In the vapor
