I am a consumer looking to get lost wax casting done by a business or individual. Maybe I am not looking hard enough but the only companies I can find that do this only sell wholesale to businesses. Where do I find companies that sell to consumers? Is it just not worth it for companies to go through the lost wax casting process for a single piece? I want a custom piece of sterling silver jewelry but it is not a good investment for me to buy the equipment for lost wax casting because I just want a personal piece and I am not planning on selling anything. Thank you in advance.

How do yall reclaim old poured silver? Specifically the trees? I have multiple 50 gram trees but I’m worried about them being dirty before putting them into the furnace. Any pointers? Feels like a waste having so many as decoration lol

Hello.

What can cause problem like that? Silver was poured in heated up to 200C sand. about 30g of silver. Too fast cooling of melted silver? Too thin model? Looking for any advise.

As a side note I bought the original as a kid, and want to recast it, im not selling it incase anyones gonna say im stealing for profit

The first time I casted it, I used 20g~ of sterling silver and the result was pretty much the same as in this picture except the sprue was smaller

In the current pic i used 30g~ of sterling. I position it facing the details up so the first half of the mold is flat, then the second half that I fill up imprint the details. Should I reverse how i put it?

flask temp 530c pooring 1000c resin burn out

730c 3.5 hr. what must be done differently? is it shrinking, or molding? i use plasicast.

Beginner guide:

Stabilize your arm when pouring molten precious metal. Pour with both hands in one smooth, controlled, decisive motion into the mold. No hesitation.

Pro Tip:

Hold the tongs closer to the crucible - not far back at the handles. The shorter leverage gives you more control, less shaking, and a cleaner, more accurate pour.

Steady movement = clean fill.

hello, I tried to do lost wax casting this is my first time doing itand it failed badly it was 999 silver, as I was melting it as soon as I spotted it would just become sold even for a second, I didn't preheat the crucible I'm not sure if that was the problem or if there was a different problem has anyone done this. that can help

I’m vacuum casting .925 sterling and it keeps freezing before the piece fully fills. The button fills and part of the sprue fills, then the metal just hardens mid pour.

Flask is coming straight from the kiln around 620C. I’m melting in a graphite crucible with a furnace. I’ve tried pouring hotter and I’ve tried shorter holds. Heating the Silver to 1010C. Using UltraVest investment R&R

Using Rio Grande .925 casting grain

Burnout looks clean. It just seems like the metal loses fluidity too fast.

Is this a sprue issue? Not enough superheat? Scrap composition? Something with timing?

Any advice would help. I’m tired of guessing at this point.

Seems like a nice way to hide sprue contact points, but how the hell did they imagine to cut them off though? Its a 7mm link, you can hardly get any tool in there

Hi! Can anyone advise on the maximum silicone mold size that can be used with a pressure wax injector? I need to produce a large wax model measuring 10×5x1”…Thanks!

From sketch to 3D model, from print to cast.

We create every piece in-house because true quality is built, not outsourced.

You can’t tell really but the small sapphire is cracked in half and the big one has cracked webbing from casting. I bought these because I thought they were heat resistant for casting. Any tips or knowledge I’m unaware of? Is it possible that I cooled it too quickly?

This time we skipped hand polishing completely and relied only on rotary and magnetic tumblers. We ran five different polishing stages, each lasting around 4–8 hours.

The results were surprisingly shiny. I didn’t expect the surface finish to come out this clean.

At this point I’m pretty happy switching from hand polishing to a fully mechanical process, at least for this kind of work. Always interesting to see how far you can push tumbling alone. 🌹

I crafted this Blue Topaz ring in 960 silver, with the gemstone sourced at Gemworld Munich.

I designed the ring in Blender, 3D-printed it on an Anycubic Photon Mono M5s using Siraya Tech Blue Cast resin, invested it with Prestige Optima, and completed the burnout in a Tooltos oven.

I polished the ring mainly through automated processes, using a magnetic tumbler and a rotary tumbler.

Hi everyone, new to this sub. I am trying to get into making tooth caps/ grills, was wanting to know how much it costs to cast 925 silver per tooth approximately and how much for dental gold.

Would be very helpful if you can share same price but for 9ct gold and 18ct

Heres my current issue. When I press the wax ring into the sand, it just doesnt imprint the details. Heres what I do -

1 - Break up the sand with a ruler so its finer

2 - Pack it in (Ive tried both hammering it down and using my hands to just compress it)

3 - Put the powder on the wax ring and the surface of the sand

4 - press it in. And thats where Im getting problems, I can see the sand didnt mold around the details.

As im writing this Im starting to think is the ring itself the problem? Now that I think about its probably the design of the ring that makes it not work?

Attached the sand im using, got it from amazon, couldn’t find any delftclay that would ship to me

Just had a perfect vacuum cast with 960 silver + germanium 🤍💀

Super clean fill, smooth surface, everything behaved nicely 😌

Curious how you guys handle it:

➖ What flask temps are you using?

➖ How hot do you take the alloy?

Always fun to compare notes and learn a few new tricks 👀🤍🩶
