How to build a verneuil furnace for synthesizing corundum? Answered

I've been researching the verneuil process for a good while now and I'm absolutely sure i could synthesize gemstones in my garage, the only problem is that I haven't the faintest idea how to build the device I need to do it. Aside form the few demonstration pictures I've found and a hand drawn sketch of the original furnace I can't seem to find any technical information on the design. Anyone have any ideas on how I could do this?

I just started looking into this and basically came to the same conclusion that this could be done in a garage. I know that if you were to use electrolysis you can generate Hydrogen and Oxygen gas but splitting water molecules. As far as the hopper for the alumina and the rest of the combustion chamber, your best bet would be some kind of ceramic, because metal would melt at that temperature. Generating the vibration in the hopper can be done in a number of ways and really just needs to be done in a way that does not crack the hopper. I should probably mention that I am in absolutely in no way an expert on this or designing such devices, these were just the thoughts I had when I read about this process. The best way to figure out a device would probably be to come up with something, try it, asses its performance, come up with a solution to a problem, rinse and repeat.

Well for one thing, you'll need a large source of hydrogen and oxygen gas.....
