Excellent job Andrew! Very well explained. I love watching your videos!
Wonderful video with step-by-step explanations of melting gold. This is great video to rewatch as a refresher,especially before melting gold in one's own studio. Thanks a million!
I just bought this tip. Thanks for the demonstration.
Delightful informative video as always. I often put soot on molds like this. Saw someone do it a generation ago, as part of casting Tin soldiers of all things. It just became my general method. Especially if using an Acetylene torch, you have a free soot-generator in your hand!
I love watching your videos! Thank you for all the tips on melting gold using the rosebud Smith torch nozzle.
i`m an amatuer with this . just got my first crucible and have about an ounce of 12 - 24 karat gold cut into bits to work with . today i found i need a better directional head foro my torch as i cannot get into the depths of my cup with a standard hand held plumbers torch . any advice for someone who will have to buy low end hand held torches? OH and a fun thing i discovered years ago , if you happen across an "ove glove" at a drug stores as seen on tv isle or where ever , absolutely buy it . t is made of kevlar and nomex , you can reach into a burning firepit with the glove and hold a flaming ember besotted stick for a full 3 minutes before you feel and heat XD.
I think it was your best nice and clean video in melting ... very exact and essential tips and tricks explained very nice and briefly ... cool ! ♥
Thank you for your informative videos.
Andrew, thanks for your videos. I'm semi-retired after 52 years in this game, was never work as I always enjoyed the trade too much. I recently purchased one of these tips, but at the time didn't realize it was for propane, I'm set up for acetylene and was wondering if you've herd of any one being able to switch this tip over? Something you might want to try, I use a 3/8" carbon rod, coated with a bit of boric acid to stir my melting pot, picks up the impurities, springs, and excess dross keeping my crucible clean for next time. Cheers, Bill in B.C., Canada
I just got a little torch and a multi orifice tip... I need to make a silver ingot today. Thanks for the help!!
I love my rosebud smith little torch tip!
can you use the disposable oxygen/propane tanks with this tip or do you need tanks with a regulator on it...hence the larger $$ tanks?
Very clear. Thanks.
Great videos! All informative & humorous! Quick question please. I have mixed scrap and some rings have small precious stones. Can I just melt with everything and hope the borax captures it on side of crucible? Oh, also how would I recover those stones?
Hi,thanks for your helpful video. I want to ask if you use any exhaust hood when using torches indoor?
that looks like it works very nice. how does it work on really small gold? the gold i am getting from my groups claim is 30 to 50 mesh in size.
andrew berry, i been watching your tips videos which im very happy and thankfull.
im beginningy jewelry designer &jewelry maker carrer here on the UK .
I been having problems with my new welding equipment i bought in Rio Grande U.S , i bouth both of the smith regulators. to fit in a 9. 16" outlet oxygen cilinder but uffortunately the outlit uk size is to small to fit in my us regulator.
its allmost imposible to find the oxygen adapter. is theres anything you recommend?
kind regards
Eduardo Delgado
Great video. I run my torch on oxygen and acetylene - can I use this tip?
Thank you so much Andrew!!
Is the borax and flux the same thing or are you using two different powders?
I noticed that you have a little fire box that your working in can you tell me what it is made from. By the way very good video on that melting gold. Thank you
Thanks! Question: Since my shop is in my garage everything gets dirty. No way to fix that. So I have the special tip called "rosebud" here n the US. It's very dirty and I have to melt some gold. How can I clean it? There's a layer of dirt and grime all over every sq. mm of it. Should I soak it in something? Vinegar maybe?
Your videos are the best! A bonus is that the way you narrate reminds me of Michael Rosen's Hot Food poem :)
Very curious if this tip will screw on to the bernzo wk5500ox mini torch
Can you use this rosebud tip for alloying gold. I am have 10 grams that I want to do is into two 5 grams bits to then alloy each into yellow and white 18k. Can this be done?
Thank you! Great video! Have to buy that tip! Should you have dedicated crucibles for silver, brass, etc.? Also, the borax you coat the crucible with and the flux you sprinkle over the gold are one and the same, correct?
Yes, buy seperate crucibles for each metal and also for each coloured gold too.
Yes, its the same powdered borax.
oh this is very helpful.
I think I also need a bigger tip...takes ages to melt metal with a pinsized tip, feels like im pumping out more fuel than I should need as well
and getting the metal ready for the pour, is something I also need to fix.
lots to learn, lets hope I wont get lost and become a jeweler...
Are u using the Rosebud tip
What psi pressure are you gas & Oxygen set at to give the flame that strength/hiss?
Hello Andrew, thank you for the nice video
I’m trying to melt a silver spoon marked
15 DWT with my mapp torch, torch, specs says that it can reach 1900 C
It gets red hot but it doesn’t want to melt
What am I doing wrong
Where can I get heat box or whatever it’s call that he is using the crucible and flame in ?? Is there a name for it?
Hello, I've got a different torch that attaches directly to a cartridge (which is 600ml of propane-butane mix), and yes it melts silver in small quantities, however, if I put a little bit more, like a solid piece of 40g (about 1.5 oz.) of 925 silver it just won't melt. I've been trying to melt it for almost an hour and nothing. It turns the silver into one solid glowing piece. Can anyone help? I don't want to saw it into smaller pieces since I feel like it's just a waste of material
HI Andrew, How do you set up your smith mini torch to oxygen tank and can you make a video on that?
I can’t get this to work using the tip and torch he’s using. I am using propane and oxygen. I’d like to see what tanks and regulators he has.
Nice sir, were to buy that kind of tourch I'm from Philippines, tnx
I’ve tried this and can’t get it to work. I’m trying to melt bronze which is a lower melting temp than gold. Using the same rosebud tip plus same Smith mini torch and same gas (propane). Andrew, what tank system are you using? I’m using disposable tanks and the oxygen runs out after 20 minutes. The metal never gets hot enough to pour out of my crucible. It turns into a rock before I can drop it into the ingot mold.
Hi what psi is your oxygen and gas?
You can do that with a propane torch and i make a channel in a kiln brick for the mould
Hi! Where do you get your square crucible and handle/holder? I’ve never seen that shape and it looks like it would be very easy to control while pouring ingots. Thank you!
Here in the UK you can try Betts metal sales in Birmingham
How do I clean a crucible? The solder area you have(with the side wall) does that help maintain the heat. If so where did you buy that? It seems to take me a lot longer to melt the gold, I did purchase that porch tip after watching this video. Thanks for all your great videos.
Hi try this video ua-cam.com/video/P3K9RHyyWRk/v-deo.htmlsi=iG_jEgVbRF-F4izJ
hi Andrew I have a cast iron crucible never used it but I do intend to, what please is the right thing to coat it with do I just use oil or flux, how are you getting on with the engraving?, great tips spot on advice enjoy the vlogs thank you.
albert partridge Hi Albert. Use oil and NOT flux to coat the mold.
hi Andrew sorry to bother you again , what do I coat the cast iron crucible with please not the mold .
A cast iron crucible? The coat it with flux. The mold that you pour the molten metal into, use oil.
Engraving? I have used it a couple of times but nothing serious with it yet.
If I were to make something like a signet ring or class ring, would it better to start by casting it? or with a silver/gold bar?
??? Well, I think people cast such things to economize on material and to allow very elaborate work. If you start by making a solid piece, will you end up carving it into the form you want? People DO that! It might generate a lot of waste? I think it's something you have to decide based on your design.
Thank you! A great video!
Can we use boric acid instead of borax? Thank u in advance!
People often mix them to make flux. I do that. More boric acid though. I think I know one jeweler who uses Boric Acid exactly, the stuff that comes in a big squeeze bottle and is sold as roach poison. Borax is common and cheap! Sold in ordinary stores.
Good day Mr. Berry. What type of acid should I use to remove the remaining flux on the gold ingot?
Sparex #2. You can find it on Amazon. Also works with silver and other metals.
Great video but I have a question that how long can we keep on using that burner or torch?I mean can we keep on igniting it for hours or do we need to give it a rest?it is dangerous to keep it on ignition for hours because it could get too hot or can we use it for as long as we want?
why would ur torch be on for hours ever?
Would oxy/acetylene be too hot ?
Can you use just a propane torch to melt 925 silver
Do you use a O2 concentrator? If so do you use for a backflow preventer? I see a lot that say don’t use anything on the o2 but Do on the propane?
I don’t use a back flow preventer on the oxycon as there is no need but I always have one on the propane
Andrew I am new in the jewelry game do you have to prep the crucible before using and if so how do I do that thanks
Hi. I did a video many years ago now. Take a look here search for Preparing Your Crucibles Before Use
Hello . What LPG gun name ?
can you use the same set up for melting sterling silver for sand casting jewellery?
thank you for your reply :)
it would be moisture in the mould which creates splatter
Thanks for this video. My melting rose bud is in the mail as I was not successful with my no 6. Now my problem is, I use acetylene (propane not available in Sarawak). Can you make a video on how to control the acetylene?
Sorry. We don’t use acetylene in our workshops so will net be able to help
You can't use this propane tip for acetylene.. Smith does sell the same one made for acetylene.
yeah thanks .so if you had spring or debri under the flux in a cold crucible what would you do ? heat it up and try to get it out ? before your next melt thanks
Steve Green Usually I would stand the crucible on its edge and heat up the crucible for the excess flux to run out. Even if you did not do this, the springs will be held in the flux and won't go back into the moulted metal.
right thanks iam calling it a spring not right sure what it is but can see some thing dark under the hard / cold flux .I will try that and thanks for your quick response
Steve Green I don't understand. The flux holds a spring in place while the gold pours out??? Huh??
huskyfluffy yes. The flux hold onto any of the debris such as ash and the bolt ring springs
can i use oxygen concentrator over oxygen tank to melt gold???
Can you use disposable propane cans to melt and do you need flashback arrestors for propane cans
Yes you can and no you don’t need flash back aresters on disposable cans
Hi, are flashback arrestors required with the Smiths torch?
Yes most definitely
Good day from Canada. Please let me thank you for all your help. I have been learning so much watching your videos on UA-cam. Since my retirement I decided to start doing rings with silver and been having a lot. Of fun doing it. I keep all my scrap and test that I did and decided to melt them down to make new project. I get my silver to melt nicely then I poor it in a little mould that I got and make little bars. Then the trouble starts. Since I don’t have a press I try hammering down my bar and it cracks on me. What do you think I’m doing wrong. Since I’m doing this for pleasure I don’t want to invest in a press do you have any suggestions thank you in advance
Francois
scrap metals have impurities like solder, ur bar will crack because its not pure metal, best bet is to use fresh metals and casting grain. thats just my theory. but no one has seemed to answer ur question yet.
Try aneling the metal every so often to soften it , hammering it hardens silver and it will crack.
Great video, Thanks for sharing. My inner H & S nerd kicked in.
1) Do you have air extraction over your casting area, the burning oil gives of some seriously nasty chemicals?
2) I do melt silver and find that I get a green burn to my retina, if you are regularly looking at molten metal should you not at least use a darkened glass? I find polarising sun glasses prevent the dreaded green spots.

With the amount of infrared light being emitted, you can in fact do permanent damage to your eyes. Best to use some flip-up torch glasses that will filter out that infrared. A complete guess, but I think shade 4 should be sufficient - people silver brazing bicycle frames generally use shade 4 or 5.
I have this old rolex lady’s watch that can’t be fixed I would like to have it melted down for its gold can any one help me or send me in the right direction. Thanks jim
Hi I have one of these tips for my little smith torch, which I used to try melting down 18kt white gold containing palladium but it would not become molten. I’m using oxygen and propane .what might I be doing wrong?
Certain alloys of 18ct white gold just wont melt down and you have come across that alloy. You won’t be able to melt it down at all not even using the smiths little torch. I would send it off to the refiners and get some fresh gold in return albeit a lot less in weight
You're using the wrong torch, you need a Hoke.
I would like to ask you, which torch to buy if i want to melt 1kg silver bar. Same torch i would like to use for small amount of silver or gold. It gona be my first torch, but for a long time i hope. :))
Edgaras Pavardenis You won’t be able to get one torch that does both of those jobs I’m afraid
Edgaras Pavardenis A sievert torch that runs on propane tank with a pencil nozzle is good as you can change the pencil nozzle for a larger one too
Hello I am come from cambodia
where can i get those brick housing for melting metal?
You can make your own ua-cam.com/video/7GZPsXYgRWI/v-deo.html
Andrew how do you know when you are burning the metal?
Sparks.
I bought this tip from PMC Supplies in USA. It is hard to find and was a total of 68.59 US dollars. It arrived 10 days late, the tip was broken off. I took it to be repaired and they said it must have been a returned item that they attempted to repair and failed. It has fire scale all over the copper and the break was just the solder blob that cracked off. So disappointed, i have tried to contact them but the email contact on the site says their is an error and I cant get them on the phone......
You said to burn off the oil in the mold, but you showed pouring the gold in with liquid oil still IN the mold?
Me Now I was wondering that too. I think he meant that the oil will burn off, when the gold is poured on top of it.
is it dangerous oxygenated flame with oil?
It’s only a small amount of oil and it burns off leaving soot on the mould.
It was so nice the gold came out. Can you send me one
Will this method melt platinum?
No.
That tip is called a rosebud in the pipe fitting trade.
Hi, why only number six??
huskyfluffy Once you know how to handle the torch and the flame you don't need to change tips. Experience plays a big part in this. It's not all about the wand but how you use it.
I see what you did there!
What happened to the tiny springs? 🙄🥺
was upset you did not show how to clean that ingot
There was a bit of copper that burned up there. Sneaky jewlers.
Wouldn't paraffin used in candles be better than oil for non-residual effects? 🤔
It’s the carbon that is left by the oil that makes the metal not stick to the ingot
@@Atthebench Yup. It is clear. What I say is, if it is not less harmful for the alloy to settle in paraffin than in oil. I am referring to the possible creation of more toxic and dirtier waste. I have always used paraffin, which is more volatile.
A Hoke could do that with a regular tip.
I have the old Rolex ladies
You don’t use a lighter to a torch like that bad on your part
orthophosphoric acid
I took a gold nugget n just put a torch on it and it exploded
It had quartz in it.
You said to burn off the oil in the mold, but you showed pouring the gold in with liquid oil still IN the mold?
Me Now when the ingot mould is new, that's when you should burn off the oil initially. This ingot mould is many years old and has plenty of carbon on it. So the ingot pours better with excess oil in it.
Me Now so put the flame on the oil?? Before pouring in the gold?? All the time Or once?
