This Instructable is about casting and finishing a ring using the art of lost wax metal casting. In lost wax casting, a wax positive of the final product is carved and embedded in plaster. The plaster is then heated so that the wax drips out. Finally, molten metal is poured into the negative impression left by the wax.
My ring has dual snake heads emerging from the ringband. I picked these because snakes seem to symbolize power, prowess, and deadliness, which are cool to display on a ring. You could use a different design, as these instructions apply for a wide variety of lost wax casting projects.
Your finished product will be shiny, smooth, and handcrafted by you! You could use the ring for yourself, for a gift, for a secret weapon of power, or for displaying your handiwork.
Enough talk, let's get casting!
First off, you will need some wax to carve into the ring. I just used old broken crayons. Grab a bunch of crayons, remove all the paper wrappers, and place them into some sort of melting pot. Unless you want to spend hours scrubbing wax off of your cookware, avoid using eating stuff. I used a cut-down soup can, and it worked very well. Place the crayons in your melting pot and begin heating the pot over the stove. If you have a range hood, you may want to turn it on now, as melted crayons can make some annoying fumes. When the crayons are all melted, pick up the melting pot with some pliers and smoothly pour the wax into a mold. The mold should be something like a small popcorn tin lid. These are great because they have a small diameter and smooth, straight sides. Thus, they create a nice-sized disk of wax that can be easily removed and carved. Basically, the mold needs to make a chunk of wax that can be removed and carved into a ring. If you pour the wax to be as deep as the ringband is thick, carving will be easier. Once the crayons have been poured, let them cool and then place in the freezer to chill them further. When they are nicely cold (cold wax seems to be easier to remove than warm wax), pop the wax blank out of the mold.
