You would be better off pouring with the tongs straight out of the furnace. You have less than 10 seconds to 'finish' the pour from the time you shut off the propane, the melt will cool immediately down below pouring temp if you wait any longer - you also have that massive cone mold which is cold and pulls all the heat out of the melt. Try setting the cone mold on top of the furnace for 30 min to preheat it. Also put your crucible back in the furnace and close the lid so both the furnace and crucible can slow cool - rapid cool of either is what destroys them. Soda ash is also extremely corrosive to crucibles, so go light on SA and heavier on the borax. You're doing great! Happy to see your making progress :)
Thanks for the tips Gold Miner! I will definitely try to do the pour a bit quicker and see if there is any difference. Sounds like you've don a bit of smelting. On the second pour, the BIG button turned out to be lead n gold on the bottom and iron n gold lightly coated in lead on the top. The iron cap has gold in it and seems to be a bit of a "refractory" possibly from the addition of some graphite from the crucible. Any idea on how to go about smelting that?
@@ColoradoGoldCamp It's best to heat your furnace up to temp first, then add the crucible, preserving the graphite crucible. You will prob be better off with some greenAP cheapy crucibles if you are going to be using soda ash. Borax is your friend ("Anhydrous" borax over the store bought water laden borax)
@@ColoradoGoldCamp You likely have several issues going on in your charge, one is the sulfide amount, the other is iron content. Pre-roasting helps off gas the sulfer, and you will need less iron in the charge then, or if you have a lot of iron in the mix from your pulverizing machine, that can be removed with a magnet. It's a fine balance iron/sulfer. It's better to pull the iron with a magnet and add a steel rod into the top of the crucible that way the smelt will only consume what it needs, nothing more so it's self regulating. Too much soda ash can also cause the lead to suspend. You might want to add some glass ( silica ). You saw the difference of the slag from your first to your second pours, so you have a good eye. Smelt fluxes recipes are not easy, every ore is different, even in the same sample vein, but you have obviously done a lot of research as you are doing way better than most this early on.
Your doing great. You might consider using a different pair of pouring tongs. Those look quite difficult to flip which is the last thing you want around dangerous temperaturea, cheers
Cool video! I work in a machine shop but we also pour all of our parts that we machine. I don’t know if you did this off-camera but it might help you if you put your cone mold on top of the furnace and get it good and hot right before you pour also if the cold mold is too cold you could have a explosion from the different temperatures they are not fun! In the first pour it looked like you didn’t quite have the material hot enough but it’s kind of hard tell. I don’t know if I would really be any help with this kind of foundry work but I do live in Colorado if you ever need help.
Cool Stuff, sounds like you do interesting work Lmeyette! At times it can be difficult to tell when the melt and reactions is completely done. The first one cooked for 54 min and appeared to be done. Once, poured....clearly not. That pour also resulted in a matte throughout the slag but did yield a decent gold bead. I did semi preheat the mold but it likely needs more, for that, I'm gonna need thicker gloves ;)
Hello Mr Colorado. You truly live the American dream life.🇺🇲. I whis i could some day live the free life like you. You working hard to. You passion shining to us who follow you. You truly deserb many more to follow your great canal🌹. Thank you, and god bless you, and the famely sir. Arne from🇳🇴Norway
What did the parting reveal , you only went to precious dore and color means nothing till the cornet. What was the final cornet weight. Your 100 plus grams is industrials and everything else that can be reduced.
I don’t know much about this stuff that’s why it was so interesting to watch. I do know fumes are dangerous so I worry that you were downwind as you poured. I guess once you start you can’t easily move so if the wind changes it puts you in a precarious position. Maybe you should wear a respirator to be safe. Maybe I’m worried for no reason...I tend to be overly safe or worried about safety sometimes. Anyway, that is quite the process. You have all this fancy stuff to melt the metal...how did the old timers do it?
Thanks SCS. The use of a high quality respirator with the proper cartridges is Extremely important! I do use one :) The process is fascinating and ever evolving as all rock types are different.
Get yourself a surplus fire approach suit. It looks like a silver suit with a gold face shield. It will make pouring gold so much more comfortable. You won’t catch on fire. I used them when I used to pour gold bars.
Ya maaan, that is the Devil Forge. It is the version with 1" kaowool, 1" refractory. Really well made and high quality parts compared to others I have seen. Smelting with flux makes a quick mess of a nice clean furnace though ;)
Man I'm loving your vids!! Although I was so ready to see the second one!! Lol my jaw dropped at the end. Hoping its coming soon! Thank you for showing us the process!
I need to get a kiln and learn how to do this, I can not wait to melt some gold and pour a big bar or try casting something for jewelry. Great video!!! it blew my mind to see the Cupel absorbing the lead, soooo cool.
Long before I started placer mining I was milking and smelting gold & silver ore that is a hoot! You definitely should try it out heck make yourself a impact mill & a kiln "fairly easy" and I know for a fact you have refractory ore all over your area that would yield gold after the process.
Ooooh, it's so wild Andy you would love it! Look into cuttlebone casting as an easy cool n fun way to make some crude jewelry or custom coins. Melting straight gold is easier and cheaper to get started with, let me know when you pour your first 10oz bar!! Cheers Mate!
Why don’t you preheat your mold that way the dense gold at the bottom of crucible gets enough time to settle at bottom evenly? Most you tubers advice is to preheat molds.
Need a little potassium nitrate or similar to eat up those oxides a bit better. A pre roast may even help a bit? Should leave that iron bar in a bit longer too would help some. You can lose small (and not so small) BBs into that matt layer and its just a pain to bust it up and fish through it or crush and smelt it again.
Awesome man!! Maybe one day I can collect enough to make a heck of a bead. We will be out your way this next week making a couple videos in Blackhawk and then in the desert out west wish us luck
Are you supposed to stir the contents of the crucible? I've never seen it done before and assume the contents are supposed to separate into layers before the pour.
Connection with the earth and the components that make it up. Smelting seems to invoke ancient instincts that fullfil long ago felt pleasure. Lol make sure she's good and hot before pour. Stirring and drossing seem to interrupt metal sinking process in my experience but hey your rockin here. Thank you for your humility and knowledge. I hope you get more gold in your future. ☺️
Your skatting uphill young man ;) While fire assays work, way too much effort and energy to pay. There is a reason the oldtimers went strait out of the stamp mills into quicksilver ;) Same reason if they ran into too many sulphides, they hunted better rock ;) Propane, cupels, Graphite, and time exceeds the extra bit of gold you gained with those sulphides. Trade that junk for a good tumbler, a bottle of mercury, and a retort or a bit of nitric to reclaim your mercury. It is also far more dangerous than amalgumation!! One drop of sweat hits that, you got an explosion and 2000 degree metal goes all the way to the bone!!!

@@AUMINER1 I just commented about a pre-roast, A good idea for sure how about changing out some of that SA for Potassium Nitrate?
Cool video! I got a ton of stuff to melt I should make a video 🤔
You should do it Paul! Melting rocks is almost as fun as blowing them up!!
Make a king size candy bat bar !

He who "smelted" it, "dealted" it!
(As bad puns go, I think this was golden.)
Ha some of the sulphides mite smell like fart lol
This flick did the trick ! Gold tricks are my favorite! Fun vid bud
Hehe, yes they are Adam! Voila!!! Magic!
finally we get to see some shinyG :)
Yea buddy!

Definitely worth looking into. That heat is no joke, one slip could be disastrous! When it's cooler, I wear a Nomex jacket.
Love a good cliffhanger😂
That looks like my devil forge.
Is that what it is?
Ya maaan, that is the Devil Forge. It is the version with 1" kaowool, 1" refractory. Really well made and high quality parts compared to others I have seen. Smelting with flux makes a quick mess of a nice clean furnace though ;)
bust up the crucible and cupel each piece with some base metal. possible.
Definitely possible!

Always, always, always, wear your eye protection!!! 🤠
Absoultely Ronald! I wear UV eye protection🙌
Can you do a video showing the ingredients/fluxs you use and quantity for smelting gold from black sand cons Thanks
Did u make that cone mold,i like how easy the slag button comes out.
I bought this one and it was definitely worth it.
Why don’t you preheat your mold that way the dense gold at the bottom of crucible gets enough time to settle at bottom evenly? Most you tubers advice is to preheat molds.
Absolutely Louis. I preheat the mold on top of the furnace.

Awesome video I wonder how much gold you’ll get out of the second one
Time n heat will tell!
Soooo??!!
Your pulling metal that had absorbed in the graphite thats where it materialized its why you alway process your crucibles after there done
Great videos 👍🏼
Awesome man!! Maybe one day I can collect enough to make a heck of a bead. We will be out your way this next week making a couple videos in Blackhawk and then in the desert out west wish us luck
Enjoy the mountains n heavy pans!!
Also preheat your button mold before you pour your melt into it.
awesome
Awesome!
Great video
Thanks Rip!
Nice! I tried cupeling some karat gold jewelry. It didn't work out. I don't think my kiln got hot enough. I'll give it another go.
Borax is the key and a gas mask.. the soda ash will eat up ur stuff
Absolutely right Sara!
Perfect working hot . I should try to make more videos
Thank you so much,pls can we smelt goldpin dust with soda arch and borax pls Sir give me the idear.
الله يهدي قلبك للاسلام لانك علمتنا الكثير عبر هذي القناه وانا اتابعك الف شكر لله ولك
Super video! New here. You are added. I melt metals. I haven't started refining yet. But it is in the plans!
Welcome SS, melting metal is great fun! Just be careful, fluxes and smelting can quickly and easily wreak havoc on your furnace.
I will definitely keep that in mind. Might refine the chemical way
…it wasn’t done. It was still boiling away,
Correct Joel. It had settled down dramatically at 54 min and I jumped the gun a bit on the first one.
mercury. then some nitric acid to get rid of the mercury. pure gold. watch. two toes. northern california. have a good day.
Wow so cool, I will take a guess on that second button and say 8.45 grams of shinny:)
I'll take that Dig! I will be working on it here in the next day or two.
May you tell me and how much amount of borax and soda ash for 500 grams of sulphide, Sir
Your first pour might have not been quite up to heat. Also, preheat the cone mold.
Absolutely, thanks Xe!
Did he ever do the second one?
Are you supposed to stir the contents of the crucible? I've never seen it done before and assume the contents are supposed to separate into layers before the pour.
No. Maybe for small assays it's ok. But no, don't stir.
Well, looks like I’m buying a furnace
What is the ratio of flux to cons?
How did ya smelt ..smelt good .. did singe a coupla nasal hairs .. burrt you.ll get that ..😁pip pips
Cara membuat alat pembakaran nya..atau harga alat pembakaran nya..
A lil arm hair singe is to be expected ;)
Little mire borax? Thin the mix an let the gold settle better
Hi sir ! Nice video . Where did you buy your cône mold ? Please share the info
What is the material that was placed with the soil?
So, you mean mining is NOT like in "Treasure of Sierra Madre"? 😳
I live in the UK where can I get a cone mould like that?

Did you ever cupel that giant button?
Sux when it's already hot outside.
Heheh, sure does Ron! Smelting is about as roasty toasty as it gets!
So where's the 2nd one?
That's a nice button of shiny ohh buddy I want to play☺🤙
Where'd u find the big cone mold?
