Carbonate Flange (IMAGE)
Caption
This is a carbonate flange on the side of the Z mount, fluid is coming out underneath the flange and is ponded underneath it. The fluid is at 290 C and it's in contact over a few mm with 2C seawater. That sharp interface between two fluids that have different refractive indexes, or changes of speed of light which makes them a reflective mirror like surface. You can see the image of Subastian reflected.
