I’ve just discovered some wax materials that I’m very excited about! Yes, that’s right, I just said I’m excited about wax….what of it?
I’ve been diving more seriously into the world of casting, and I like some of the creative doors that the process opens up. I wanted to start creating my originals from something other than the expensive brass that I’m used to using, but I needed the tolerances and machinability that I’ve grown accustomed to. I’ve found a couple of professional grade materials that will work great!
The blue stuff is really rigid, and is referred to as “Machinable wax”. I can throw it on my machining tools, and cut it to close tolerances like it’s brass, but it’s MUCH cheaper, and is easily recyclable. I can then make molds of the finished shape. Once I have a mold, I can either make pewter castings, or make a wax positive for bronze casting. The latter is where the red stuff comes in.
The red wax is called Protowax. It’s also very rigid, pours detailed and accurate, and doesn’t distort when it cools. This can be used to pour the final positives which can be used for lost wax bronze casting. It’s possible it will be too brittle for my work, which is typically pretty thin. We’ll see.
Casting metal can be a long tedious process, but I think it’s safe to say I’m used to that. Every new technique has a learning curve. I’m excited for the things I’ll be able to do once I have my particular application of this process down.
