Making a ring using the lost wax casting process.

I am getting going in garage. I can weld and a decent sculptor but never anything this small. Tedious process as well but it’s making me more methodical which I need. I have a centrifuge and a similar furnace. Getting started. Thanks for the videos

This is very similar to the way it was taught to me in college, except we used a torch to melt the metal rather than a furnace. Such a fun class! Thanks for the refresher!

[@MrLuvbizwar]

Nice! Do you have a video discussing how to mix the gold and silver, such as ratio?

[@arcticserpent]

This was white gold; you don't mix gold and silver.

[@marvinearl3423]

Usually, the silver content in 18K yellow gold can vary between 10% and 13%. A typical 18-karat yellow gold alloy contains the following metals: 75% gold, 12.5% copper, and 12.5% silver. Another common 18-karat alloy contains the same metals in the following proportions: 75% gold, 15% copper, and 10% silver

[@Preacher_.]

I have a silver ring from my father that's unlike anything I've ever seen anywhere else. It looks like a thin round silver band (like a single band of a keychain ring) with silver dripped over it in a cool almost eye shaped pattern on the top, with a hole through some parts, and silver overlapping itself on others. There's tons of little crevasses and buldges down the side and literaly looks like silver dripped down the sides. He had told me it was a dripped silver ring that he made in his 20's but I never got to ask him more about it before he passed. Is this basically the processed he used, but instead of a carved wax mold, he just dripped wax over a band of wax? It seriously looks like someone just painted/dripped a plain, thin silver band with molten silver, is that something people can do? Or do you think the processed you used sounds more likely? Wish I could post pictures.

[@davedoessomestuff8176]

That sounds like a very very cool ring. Thank you for sharing.

[@bezeir]

Post a video and we can maybe help you discover the process.

[@Preacher_.]

@@bezeir wow.. that's actually a great idea and I have no idea why I didn't think of that!

[@lucawendel7644]

Yes i do this process by dripping the wax onto a band and using that as a mold. You can make dents into the band to make the wax droplets sit better and they should be just around the melting point so they cool off very fast.

[@GMezzacapo1]

Nice Cast, How much time do you degas after the plaster boil in the flask? thanks

[@VintageJewelersGiftsWindsor]

I usually mix for two mins, then degas the plaster before I pour it into the flask, for about two mins, then pour into the flask and degas another two mins or so. About 6-7 mins to invest total.

[@davidho7744]

[@macykeovilay6010]

Hi i have a question if you can help me, if the investment isn't mixed properly will you not get that suction pulling the metal through casting? I'm having a problem I cannot seem to figure out, I just purchased the dura bull which is identical to the kaya cast.

[@VintageJewelersGiftsWindsor]

I use a 39:1 ratio. I Doubt it’s the investment ratio though, probably the seal around the flask. However I did have a problem with the flask one time. The flask had developed a small crack around the lip and wasn’t drawing the suction through the investment. Thought it was a problem with my vacuum for a few casting until I figured it out.

[@HeinHtetAungJames]

Hi I don't understand one thing. When you put the flask into the kiln at first the flask was upside down but when you took out the hole was up top. Did you change it in between?

[@VintageJewelersGiftsWindsor]

Yes, we did flip it. Having the flask upright, makes it so it’s easier to grip it at the top, so the flask can be placed into the vacuum chamber.

[@HeinHtetAungJames]

[@sitgesvillaapartmentneilsc7924]

Excellent video, My daughter is now doing at university a design and fabrication degree, basically she will come out with a silversmith and or goldsmith, one of the things she is worried about is that they do not seem to want to do very much casting , we live in spain, its quite weird here in the "arts" , anyway she is a little worried that she will have the degree but not a huge amount of experience in this type of work which is primarily what she intends to do. You obviously have an awful lot of equipment here and I have a few questions please, first of all is on the vacuum machine, I understand the process of how you remove the air from the mould with the bell cover on the vacuum pump but I dont understand how when you pour molten gold into the mould on that machine what is does then, I though it pulled it under a vacuum but you dont cover the crucible, is it possible to explain that part of the process please. Also the kit you have adds up to quite an investment, burn out kiln, electric furnace, vacuum and casting machine , ultra sound bath. i have the last piece and I want to try and help my daughter so she can practice at home and gain experience. Of those tools are they all totally essential to make a casting? The kiln I would say yes as it can be used for a lot of other jobs as well, the vacuum and Casting machine I am not sure about, over here in spain this retails at 700 euros more or less I can buy a purely vacuum pump with vessel and valves etc for 99 euros , its made by the same people who make the big machine, Vevor. It purely removes the air from the investment mould by utilising a steel vessel, polycarbonate lid with valves and seal etc, you would not be able to use it for the casting though as it would be too slow to do what ever your machine does. I can though pick up a centrifuge for around 100 euros or do you think your machine is 100% essential for a new jeweller to get for casting or would using a vacuum pump be enough to remove the air from the investment and the centrifuge to cast. Moving on the furnace is obviously a sort of a nice way to melt the precious metals but I have gas tanks that run air oxygen and propane mic, I also have acetylene but i wouldn't like that in the workshop down stairs, that gas is inherently dangerous. Propane and oxygen will certainly melt silver, gold i don't know the melting temperature as i type this, as a student she is using silver a lot because of its cost over Gold. the iltrasound bath i actually have and can see its put to good use to remove the investment material, I also have a polishing machine, several dremels and a ceiling mounted type dremel as well for finishing, georgie does know the process as she made a gorgeous ring but they did not cast it at uni, the wax impression was sent away and the cast was returned a few days later. Im trying really to set up for her a space in the home workshop where she can feel she can do a lot more work that she is doing at university and possibly earn some money on the side whhile she does her degree. I have already built a proper heavy Jewellery table in the typical fashion with all the drawess, cut out area and bar for you feet and lockers underneath and she loves that, They were silly money to buy and as a carpenter it was easy to make one. Would you please mind helping me out here and advising me on where i should put my money and explain the use of the main machine and how it works on the casting sie as i dont understand what its doing or how it does it. Hopefully you have some time to answer my questions, this is going to be a total surprise for Christmas, her very own workstation, I also have from the us the tiny gas soldering system which is lovely but for melting silver i have a larger tank array and torch if necessary. I dont mind investing the money if its all absolutly necessary , I would prefer to do it in smaller chunks if thats possible. Many thanks and the ring was quite beautiful finished.

I pull the flask out of the kiln a few minutes before casting to inspect it to make sure the model has burned out completely. Then I put it back in to with the hole on the top, so it’s ready to pick up and set into the vacuum caster.

Great video! How long does it take to get the final product once you have the mold?

[@VintageJewelersGiftsWindsor]

I let the kiln run overnight to burnout the model then cast in the morning. Then the ring needs to be cleaned up, pre polished, stones set, a final polish and in the case of white gold, a rhodium plating. Simple castings I can finish within a few hours, but castings with complex setting can take a few days to finish up.

Thanks, this was the solus emerald green resin, but we’ve since switched to X-one castable resin. I get good results using the 12 hour burn out cycle recommended by plasticast. Some casting with resin use shorter burnouts, but since I let it burn out overnight, the longer burnout time is not an issue.

Hi could you tell me how the metal flows into the mold without breath holes in the mold itself, like you do with delt clay?

[@VintageJewelersGiftsWindsor]

The metal is poured into the mold from the top, through a sprue to reach the negative void. The mold is a plaster called investment that is porus enough to allow the vacuum to suck air through the mold.

[@tammywhittenham543]

Thank you very much for letting me know so quickly. I tried to do it today but the white gold just didn't flow properly. It might have been the fact that my sprue was not wide enough for the metal to flow.

how do you calculate the amount of gold needed per ring any karat and if the same calculation applies for silver?

[@lordsathariel4384]

im rather new to making jewellery but my grandfather always taught me to have a little extra then what i think i need cus you will probably need that little extra

[@VintageJewelersGiftsWindsor]

So every metal alloy usually has a density/specific gravity specs provided by the manufacturer. If you weigh your wax model and sprue before casting then multiply that by the S.G. It will give you the amount of metal you need to use for the casting. Example: Model and sprue weigh 2 grams and the 14k gold has a specific gravity of 12.6. So, 2g x 12.6= 25.2 grams of 14k would be needed. Also I usually add a few more grams for the button.

No, it’s not necessary to use flux with the graphite crucible of the electromelter. It’s actually better, since you won’t get flux contamination in your casting. I just clean the gold casting sprues really well that get recast along with the new casting grain.

Good catch. Yellow gold and Rose gold alloys definitely need to be pickled after casting, white gold usually comes out fine, but I may have pickled it, since it helps to break down any residual investment, and just not shown it in the video.

[@throesofrejection4012]

So in theory could I dewax with steam, and put the investment in a propane forge to get up to temp to pour.. dont have a kiln

[@VintageJewelersGiftsWindsor]

Yes, if you’re using wax models you could use steam de-wax it. I suppose it could be done, but I doubt you would achieve very good consistent results using a propane torch to burn out the mold. Investment breakdown, incomplete burnout, mold cracking, partial fill, and porosity are just a few problems that can occur.
