How to Make Your Own Jewelry : Jewelry Casting: Part One


So the first thing that we need to do, this
is a typical centrifugal caster or a spin caster is go ahead and spin it up. We have
spring loaded casing here at the bottom. The first thing that you want to do is balance
it so that when the force of the metal is pushed to this side it will balance and keep
the machine nice and smooth and even and make your throw much cleaner. I’ve already pre-balanced
this so we’re not going to need to get into that too much. First thing I would do, and
I’m starting at this pin here is wind it once, twice, three times and I’m going to
catch it with this pin here. It’s got quite a bit of strength in there and it’s going
to give it a nice spin when we let it go. But we’re not ready to do that yet. The
first thing that I am going to do is heat my sterling silver metal in this crucible,
this is what we call a crucible. You do want to coat your crucible with a boric acid which
gives it a nice glossy surface and keeps your metal from getting contaminated and keeps
everything nice and clean for your shoot. So we slide that into your center fuse, get
the appropriate size cradle which just basically holds whatever size flask that you’re working
with, or mold. And then we would pre-heat the crucible and what I’m using here is
an oxygen and a settling torch. Most people use propane, which burns much cleaner, this
is more for welding purposes, this is what I use here. Propane and oxygen work just fine.
Go head and light my torch, give it some oxygen, that’s a pretty high flame for casting.
We want it just a little bit more lighter. And right now all I’m doing is preparing
my crucible so that I can insert my metal and have it nice and ready to melt. That takes
just a few minutes here. Going to go ahead and coat the base of the crucible with boric
acid, like I said to keep it nice and clean to keep contaminants out of your casting.
That will just bubble up and make a nice glassy surface on the base of your crucible. Once you get the
crucible pretty warm I made a little shovel type contraption to insert my metal and keep
my hands away from the heat and the flame. I’m going to go ahead and put that in, keeping
the torch on there nice and heated. I’m using here some old metal I used for another
casting. It is reusable you can remelt old sterling silver, I wouldn’t suggest just
grabbing anything but you definitely can have it tested to make sure it’s pure and clean
and all of that. And a little bit of casting grain which I buy from the local jewelry supply
store. You can also order it from catalogues. You want to heat around the metal more than
directly on the metal. To make sure it has a nice even heat on it and not overheat or
boil your metal. Silver melts much faster, it’s much softer than gold and other materials,
including bronze. Bronze is pretty hard to melt in an even matter. I think we’re going
to go ahead and add a little more boric acid to make sure it gets nice and clean. As you
can see it’s creating
a nice pool and it’s pretty close to being ready to insert into my flask or my mold.
And I’m going to grab that right now and cut off my torch.

  1. I've noticed that technical vids bring out rather vicious attacks. It is possible to be much more polite about making suggestions.

  2. Good videos. Kind of hard to find all the ones to put together in order, but good when ya do!

    Such a tiny amount of molten metal is way too little to even hurt you even if it ignores the laws of physics & flys out of there 😀 Them people that are worried about your safety should have a gander at my videos! Now, that's SRSLY some dangerous stuff..

  3. …then, there's your videos. One is of soldering a plate, and the other is melting gold. Very well scripted, I might add.

    Blatant Egotism. I don't think so. It's a video on YOU TUBE for christ's sake!

  4. Are you serious? it's a spring, a ceramic crucible, a washtub, and a balancing mechanism. I can go to my grandmother's house, and get everything I need to make this in an afternoon, because she hasn't thrown anything away since 1934. The crucible can be made with a fire resistant clay, or bought for relatively cheap, since it's reusable. All that's left is to have the cast, which you would have anyway for this project.
    Do you always talk yourself out of doing cool stuff because you're lazy?

  5. @panzuman Borax comes from the town of Boron in California and it's not been in the grocery stores lately, the factory, which mines Boron (a mineral for calcium uptake in the bones) there and calls their laundry whitening product Borax (but it's mostly Boron), keeps the entire town running and they are having serious factory union problems now and locked the employees out of work. I used Borax (in my laundry) for 35 years now. Boric Acid from pharmacies, kills cockroaches and used for eyewash.

  6. @kaleluk31 There's a bunch of make-up tutorials on youtube aswell, now since im not female nor extremely flamboyant & gay I should be complaining about them?
    Not everything applies to everyone.
    And exactly like ''Shookings'' said, one is easily built by yourself.

  7. @kaleluk31 Jasne, dla ludzi, którzy wszystkie narzędzia woleliby kupić w sklepie zamiast zrobić je własnoręcznie, jest to zdecydowane "mmmmm".

  8. @kaleluk31 My english is not as good as yours 😛 So, this tool or machanism is definetly DIY. When you prefer buy it than build it, you would be called lazy or unable to build that machine. Unable = with lack of mechanical skills. Why don't you use a translator? I think that google has a translator. And it's more fun than me vs. english or you vs. polish 😉

  9. I guess that I see goggles on the artist. But those uncovered arms frighten me. It seems a bit casual to trust that no accident could happen! I am watching this You Tube video bacause it was assigned as part of an on-line class at Sinclair Community College. On-line, right there, you know that anything can happen!

  10. @shookings not everyones grandmother is a packrat. Im sorry but I would love to do this but have no idea where to find those things nor how to assemble them. I cant speak for kaleluk31, but I am absolutely not lazy and find it a bit rude for you to assume anyone who doesnt have supplies lying around from 1934 as such. If you have a more productive suggestion Id love to hear it.

  11. I don't mean to be a downer…but you probably shouldn't have a caster in your room. If your investment blows out there is a chance that your metal fly out the back and out into the room. Molten metal is never a good thing to have flying around your room.

  12. @SLPgoogle comment was 9 months ago, but I figured I'll chime in. Oxy-acetylene will go through pretty much anything faster than a human can react. I personally wear thin gloves because the torch body can get kinda hot, but there is no way that they would help if the cone of the flame went over my hand. As far as casting safety goes, though…. It's quite dangerous to be anywhere near that thing when you release it. Ideally it would be in an enclosed metal box in case the silver goes flying.

  13. Melting Silver for Making Jewelry needs the Extreme Temperature. do you mix diff type of alloy to make handmade style silver jewelry.

  14. Hey! Thanks for this helpful video. By the way, I notice lots of people keep on talking about tutorial known as Jeweluxory Making (do a google search), but I'm not sure if it is good. Have you thought about Jeweluxory Making? I have heard some great things about it and my cooworker finally learn how to make jewellery easily, but she refuses to tell me: (

  15. Hi,
    So if you added casting grain to your old sterling silver, the result is a lower grade silver, not sterling anymore right? Why did you need add to add casting grain?

  16. That's a hawt fahr! Lookat me maw! no safety anythang, jawss mah tanktawp an mah blew juuyns! Laak muh burd taatew? 

  17. What about fine silver? I haven't been able to find anything about casting pure silver jewelry. To be honest, my problem is that my silver will not flow into the cast, it just clumps into a ball…do I need a centrifugal setup to make if flow???
