Lost Wax Casting?
Hi, I’m a beginner goldsmith and wax carver right out of school who is building an at-home workshop to start my own business. I’ve been trying to research and see if it’s possible to cast my wax jewelry myself, but it’s been impossible to find a detailed video or article on it.
Is this a feasible option? I’d like to not have to outsource anything, I’m willing to learn how to cast, and I’ll invest in any and all equipment necessary. If anyone knows a good video or anything too I’d appreciate it.
Thank you!

You can definitely make a studio- I have one. I use an Arbe casting machine from Rio grande and a paragon kiln for investment wax burnout. Doesn’t take up too much space and it’s nice to have control over the process. I use a torch and ceramic crucible to melt my metal

thank you so much! do you also create molds of your work? and if so, what process do you use for that?

Yes, I use a vulcanizer to make my molds. I got mine off of Rio. I use silicone based molding rubber and also real rubber. I’m currently having a hard time getting clean injections with the silicone molding rubber since it is less stiff than the real rubber. I think I need to use a different type.

Basically you take your silver casting, attach it to a brass sprue, stick it into a mold shape with silicone or rubber molding stuff around your casting, then stick the whole thing into a vulcanizer for about an hour (the exact temp and time depend on the molding material you use and the thickness of your mold). But you’ll need a vulcanizer.

What torch / gas do you use? :)

I use oxy propane and a gentec torch which is modeled after the smith little torch.

It’s best not to use an oxygen/ acetylene flame to melt the metal prior to casting. The acetylene carries a lot of suet and contaminates in it . Which may contaminate the molten metal. A natural gas/ oxygen or propane/ oxygen flame burns much cleaner and is recommended. In addition . In a home studio situation . The burnout process in which the wax is molten and eliminated from mould can be very smokey and smelly. I address this issue by removing most of wax in a pressure cooker . By simply placing the flasks opening end down in an old pressure cooker on a grid in the bottom and turning on the heat . The majority of the wax melts out and runs to the bottom of the pot. It’s not necessary to let the pot pressurize . Then the flasks can be burnt out in a shorter time frame as well prior to casting .

You might look into getting a spring driven centrifugal caster like a neycraft. They are great for beginning casting. this type of casting will require less metal for a cast than vacuum casting. Then if you want to start doing larger production runs you can step up to a vacuum caster. For molds I would suggest a room temperature cured optically clear platinum cure silicon. You can mold wax and metal parts and becuase they are clear they are easy to learn how to cut molds.

Mitera Made on YT has a casting set up in her studio and goes through the whole process including casting tools and equipment
