Build a furnace, create custom molds, cast a piece of jewelry, then mount a custom cut stone

Step 7 Closing Remarks

This a great way to make a very special gift. But it really can be used to make anything small and metal, the only limit is your imagination.

Depending on the metal that is being used the amount of detail obtainable varies. For example I was unable to obtain very sharp, clean edges, they always came out with a slight fillet. At a certain point you may need a centrifuge to force the metal where you need it to go. I'm currently working on a design for a home made centrifuge and will post the design on here when it is complete. In the meantime about.com has an article on lost wax casting which explains the use of a centrifuge

*warning*
Make sure you dont make jewelry out of lead. It is toxic. And tacky. And really heavy. But mainly toxic.

THe paint can /quickcrete furnace idea is pretty cool in theory- I'm concerned about the chemicals in the quickcrete- I checked out their msds - lots of hazards which could be exacerbated by heating the concrete up to metal melting temperatures. Furnaces are never made with commercial concrete, they are made with special bricks that are designed for high temperatures. The only reason I am concerned is that I've thought about making my own furnace but decided not to because of the hazards. Otherwise a great idea! I LOVE your mold/casting demo!

Lead is deadly,and shouldnt be used for anything,craft or household wise,we dont even use it in plumbing anymore because of the toxic effect and it dosnt take much.
