I used to live in a neighborhood that had natural gas and have a really nice burn out oven that I could stack full of flasks but the home I've been in for the last few years has no gas. If I want to use that oven I need to get my really large propane tank filled but it tends to freeze up on me after awhile, just don't quite understand that but at the time I need the most heat it almost quits flowing because it is caked in ice. Some less than clever folks us propane as a refrigerant substitute in their cars but it's like driving around with an explosive under the hood. Anyway I still need to get that oven fixed if I want to do any casting, strictly a winter sport now for me.

With me it's a battle of time. I have the equipment, stones and desire but stuff like preparing income taxes, waiting in line to get the car smogged to avoid huge fines, the never-ending upkeep chores around the house, dealing with the evil ways of machines that quit just when you need them most and seemingly endless obligations of one kind or another -- wow, I'm tired just writing that! But everyone faces the same hurdles. I guess I'm just slowing down a lot.

Gemfeller's photos are breathtaking. Up until a couple of days ago I had no thoughts about casting jewelry. I have just come in possession of an old and rusted Emesco Senior casting machine, which I am trying to fix and learn about. I have no idea how to use this and have found no information until this forum. I have an old small furnace and some silver. I just obtained a cabochon polishing machine that I am learning to use so the casting thing is of secondary interest. The question we have is what do you do with all those cabochons after they're made? I have some opal and some nice stones which I would like to use, mostly for my wife and children. I guess, what I'm trying to say is thanks for the information and I will try to find a jewelry class or just do more research about how difficult it will be to make some jewelry pieces like you've shown.

Thanks for the kind words Daulton. I'm not familiar with the Emesco brand but assume (from Google) it's a centrifugal machine. There are several excellent books about casting and I imagine YouTube has a host of casting videos. If you're looking for a good general manual to gain an overview of the process I highly recommend Tim McCreight's "Practical Casting." One important safety concern with centrifugal machines is making sure they're inside an enclosure. Many people use a small metal washtub so that if something goes wrong the molten metal is contained inside it instead of burning holes through the user. I use a Neycraft machine that incorporates an enclosure as part of the centrifugal design. There are commercial enclosures available through most jewelry catalogs but galvanized wash tubs are cheaper (I think).
The creative part of casting is working with waxes to create your own unique models. Taking a stone from its rough state, polishing it, then casting a one-off design for it provides a lot of personal satisfaction. One gets the same satisfaction by fabricating a setting as well but casting opens design possibilities that are sometimes impossible with fabrication. Good luck and let us know how you're progressing.
