Not quite - but it's close enough that I'll tell.
It's a small hot isostatic press, for pressing very small silicon nitride parts at 1600C, 50,000 psi.
HIPs are usually filled with argon at very high pressure, but I thought that would be too dangerous for my liking, so I'm going to fill it with molten glass instead. Pressure will be applied by screwing a bolt into it.
The tungsten wire heats it up from the inside (the EN24 shell is cooled with water). The cubic zirconia is for thermal insulation, which goes inside the EN24 pressure vessel - perhaps strangely, jewels were the cheapest source of CZ crystals I could find.
