Can you please do a video tour of your bench and talk about setup, ergronomics and the tools you use the most!
You're the best, Andrew! Thank you so much for sharing your knowledge :)
Your advice is very delicate, careful and detailed. It shows experience. It is really appreciated you are sharing this knowledge with other people :)
Always remember to remove any magnetic materials from your silver jewelry Like Steel springs and pins (from the clasps)before putting them into the crucible.
so these are not ideal for copper since you would basically need the maximum temperature to melt it?
Hi there I just purchased myself a electric melting furnace and I'm am I inquiring on how long does it take to melt gold and and is this a safe device to you vice to use and what tricks and things do I need to do to the big graphite is graphite crucible do I have to prepare it with borax it would be a really good insight if you could tell me how to use this thing before I get carried away
It take approx 30 minutes to melt a large amount. You can put some borax on the melted metal and stir with graphite rod. You do not have to prepare the crucible before hand. Use as it is
On the furnish there's a little white hole with some sort of white stuff in it is that supposed to come out or is it supposed to just be is that a feeding area where you can put your gold into the crucible I'm just asking because I don't know
The white stuff could be fire blanket that should stay in place
Would you recommend pre-heating the graphite crucible before you add the silver? Does the crucible need preparing before use? Thank you
No need to preheat the crucible. No, no preparation is needed. Use it as you buy it
crucible should be heated to 350 degrees c for 10 minutes. Pre-heating a mold is for burning off the moisture to prevent ''explosions'' when stored inside this isnt necessary
In South Australia Electrcity is the most expensive in the world, a friend uses a gas furnace, I stick with my oxy/acetylene welding set up
Excellent video!
Fantastic. Always looking for alternative ways of doing things. Thanks for sharing.
Excellent video!! Thank you so much for making this. I have been recently shopping for an electric melt furnace. This video answered so many of my questions! 🙌🏻🙏🏻
Hi Andrew! Thank you for sharing the knowledge! It will be very appreciated if you will make a video on the casting machine. I struggle with bubbles on my cast. Thanks again!
No dislikes good job!
Hi there. You said that you shouldn’t take this up to it’s full heat (1100 in this case). What temperature would you recommend to set it at for gold ? Would 1095 damage the heating element as it’s pretty close to its full setting. I’m thinking about buying one and as I do lots of remodel work in gold it’s essential I could use it with gold. Xx thanks x
good year Sir
What kind of oil are you talking about?
My automatic electric melting furnace is stuck on top number says HHHH and the bottom number I can change and won't turn on, do you no how to fix it so I can use it.
how does the furnace work? induction or heat coils?
Thanks Andrew another interesting vid. Question for you. I've dabbled a little jewellery making & casting, bone carving etc but looking to get a little more serious, my workbench has always been a normal straight edged bench. What are the advantages of a proper jewelers bunch, is it worth changing my setup.
Can you show us price points on your tools and where one can find cheep srap?
Melt down 5 g of gold then mail it for me!!! now that would be awesome
What kind of oil? A cooking oil line canola or olive oil? Or a clear oil I might use on my rolling mill rollers?
How do u scrape slag off such a little crucible ?
just what I needed - been having problems pouring into my mould - now I know why Thanks
I have this exactly mold you just used but I am still saving up to get my furnace like you have to melt my silver in. I watched another video and they sprayed the mold with WD40. Is that ok, or should I use something else?
Hi personally I have never needed to do it. As the crucible is graphite then there is no need to line it with anything at all
Wich oil you take?
When you melt a lot of silver, it gives off a dangerous gas, so always to so in a well ventilated area. Plus I think you left a spring in the clasp.
The silver necklace was broken and the clasp had lost its spring. It was one I had in my scrap pot. I did make sure there was no spring in the clasp when i put it in my scrap pot and so I actually forgot to mention it in the film.
Should we be concerned about removing the clasps? The spring in those are usually steel.
Ideally you should make sure you remove all springs and steel from the scrap. The silver necklace was broken and the clasp had lost its spring. It was one I had in my scrap pot. I did make sure there was no spring in the clasp when i put it in my scrap pot and so I actually forgot to mention it in the film.
Andrew, Thank you. I thought that, but then saw that clasp go in and thought maybe it was ok with larger amounts of silver and couldn't wrap my head around it. Thanks for another great video! Keep them coming!
Hi Andrew is there any thing you do to a brand new crucible before using it for the first time.
Take a look at this video Preparing Your Crucibles Before Use th-cam.com/video/YCels5IEqss/w-d-xo.html
I purchased a new crucible dish, a smaller one. I tried to season the thing using borax. I put sprinkles inside and every time I hit it with my torch the borax just balled up on the dish. I tried several times but got the same result. These balls of hard borax chipped right off my bowl. What am I doing wrong here? Thanks.
Oh I DID watch your video on seasoning the crucible and followed your directions. Forgot to say this in my previous comment.
Hi, how do you know if that bar of silver is 925? How can you measure the content of silver?
Very nice handy piece of equipment. Thanks for the film Andrew. Very interesting. Another item on my shopping list.
Do I need to use casting flux? I’m using the same kind of foundry for lost wax casting, previously used a torch and crucible where I needed to use flux.
Hi i melted gold rings in a electric furnace like that but it came out silver.
Probably fake rings or they were gold plated
When you say to add oil to the mold, what type of oil exactly are you talking about? Love the video, very educational for a new smelter!
Thank You! Awesome video with specific details and safety pointers!
So you don't need to line the crucible with borax?
No not if you are using a graphite crucible
Brilliant Andrew ive been looking at getting a furnice great advice as normal thanks
Enjoying your videos, finding them easy to follow, much appreciated. Can you show how to set a open back bezel for a pendant if possible.
When I use my electric forge to try & melt copper or aluminium I get left with powder & very little molten metal? Even if I leave it on full for over a hour? Where am I going wrong?
Very informational video, appreciate all the tips and tricks.
oh TH-cam channel i thought he said you cheap channel. i felt attacked for a second XD
You forgot to remove the steel spring in the lobster clasp on the chain.
Hey, I have the same one but my internal settings got changed and don’t know what they’re suppose to be. Can you hold set and tell me what your values are set for each parameter
What material did you use for your pouring station please
Just got one today very helpful your video thanks 👍🏻
Thanks for the great video! Can I ask, do you have to prep the ingot with oil every time or just the first?
Also I am looking for a new crucible for my furnace and unable to find one the same size. So long as the diameter fits ok is it fine to use a slightly shorter one or does the crucible have to touch the bottom of the chamber?
Thanks :)
Can you use it for melting copper and drink cans
Good video on this thank you and thumbs up. What type of oil did you use ?
Great vid as always. A suggestion perhaps for a future vid..I had to use the old Plaster of Paris technique for multiple solderings on the back of an handmade piece recently. Surprisingly couldn’t find a vid on TH-cam for this so could be cool to teach the newbies this old tip...(the original PUK/Lazer hack!)

Hi Andrew, I really enjoy your videos and I am always looking forward to a new one.
In the past you did a video on how to protect your fingers, but I'd love to see a video on how you choose proper protection for your eyes and mouth masks as well. I'm looking to buy protective gear, but I have no idea which protection is best agains gases released when making jewelry. For eye protection I find it difficult to find goggles that fit my small, female head as well as a good pair that doesn't scratch easily or fog up. I'd also really appreciate you pointing out when situations occur when you would need to use protective glasses/mouth masks and when not. Thank you!
Can you overheat the metal, and if so, what would happen to it?
You can overheat the metal but not in this furnace. If you did overheat with a torch it would render the metal unusable. You would not be able to roll it and you wouldn’t be able to get a good finish
@@Atthebench Thanks Andrew. Is there any way to recover it?
Neil Harris only by sending it off to the refiners
@@Atthebench great, thanks for the info =)
You must've been fabulous fun when you're kids were small...
Thanks for sharing, awesome information as alway!🖒😊
What's the name of the oil you used ond mold?
Can this furnace melt bronze or brass as well or does it not get hot enough?
It gets up to around 1,100 degrees. If the metals melt below that temp then yes
@@Atthebench thank you for the answer, I missed that part in the video. Sadly, bronze needs around 1200°C
I am very interested in recreating iron age jewelry from Scandinavia, which is mostly bronze, other copper Aloys and sometimes silver and gold. There are also pieces that combine all materials and lots of technique's.
If you want to see a masterpiece of metalsmithing for decorative purposes, look ob box brooches from the Viking age on Gotland. Some pieces have a casted body, several riveted pieces, have silver plating (as in soldered on sheet metal that is also engraved and enhanced with Niello, some garnet set in, and then thin gold sheets with relief punching, decorated with filigree work attached.
If you are interested, I can give you links to the digital archives of the Stockholm historical museum to view a few exceptional pieces
Myself thinking learning fixing . 😗😗😗
I think gold & sliver ring ? Cool .😗😗
What kind of oil should you put on the ingot mould
Thank you for shering.
Why do you need to add the new casting grain into the mixture of scrap silver? Why can’t you just use the scrap silver only?
You can use just the scrap but it is best to add new metal so it flows and works better.
i have a few oz of .999.... what would be the best grade of copper to use for making it 925......Or what would you do to alloy it for use in rings? would love to hear your take on it..
I think from my experience you need brass as just copper seems to give more fire scale. But I not found much information about 925 types as I imagine some must be better for casting and others for working?
good day Andrew, can you please do a video on making your own silver solder
Timely video, just looking at my silver scrap wondering what to do with it. Don't think it would be worth it for me to buy an expensive furnace like the one in the video. But this points me in the right direction. P.S. A reminder about safety is always relevant.
Yes it is when ge said if you pour into a cold ingot mold it will explode he's not lying. Happened to me a while back with a melt job I was doing I'm sure if I looked around I'd find some small gold around the floors of my garage. I had water and an extinguisher on hand. Nothing got burnt or lit up but I do remember seeing it explode good thing I had safety goggles on and all I remember was it looked like when a firework goes off to early and doesn't even go in the air lol just exploded and time red dots went everywhere so listen to any advice when dealing with fire flame and metal 😅
So I am planning to get a furnace to give myself more options when it comes to silver material choices. I liked the heat resistance area and am getting the boards. Did you screw them together or nail them. It was hard to see, thank you
+jarlath mcnee I used long panel pins
I have never melted any metal myself but I have a suggestion. I would think that if you preheated the stir stick before stirring the molten metal, then it would not rob the molten metal of so much heat energy. If it was heated to the same temperature of the molten metal then I would think that it would not steal any heat energy at all.
The cooling down of the molten metal is negligible when a carbon rod is used. You could also use a stick of charcoal instead
You mentioned coating the ingot with oil, What is the best type of oik to use? Thanks
We use 3 in 1 here in the uk but any light machine oil would do
Do you have to glaze this crucible with Borax
No. No need to coat a graphite crucible with borax. Just use it as it is.
Felicitaciones, muy didáctico....
nice video..amazing ty
So I’ve been trying out jewelry stuff and I’ve got some issues. My soldered joints pop open or melt if I try to come back to solder on a crown or bezel. I’m not sure what the issue is there. Second, what type of silver do you use? I’ve used a few varying gauges at varying hardness and I’m not sure if I’m using the right types of silver for the rings I want to do.
Surely if you used a harder solder for the join and a softer solder for the embellishments. The latter will always melt sooner than your join
Ad4msk1 thank you. Do you have a solder you use?
Okay since you said use a different curable with each different metals does that mean for say silver .925 and 999 in the same one or use different curables for each kt of metals?
Use a different crucible for each finess. So one for 925. Another for 999. One for 18 yellow. Another for 18 white.
Andrew Berry okay that what I thought thanks love you’re videos buddy they help a lot
would you be able to provide a link to buy this?

Great stuff Andrew. What type of oil for coating the mold?
Just any light machine oil. We use 3 in 1 here in the uk
Love the end 😂
Very helpful video. One question here, do you recommend oiling the ingot every time you use it? Thank you.
We coat the moulds every few times. There is usually enough carbon left for a few uses
@@Atthebench Thank you so much.
Very nice 👍
Hello andrew, im a goldsmith and i just bought an electric furnace but bubbles appear after annealing. What can i do to reduce the bubbles in the sheet? Thank you
