I’m not sure if this is some unvaporized mercury or some of the emissive coating from the filament, as these lamps have some use.

Take a magnet and check if those participles are magnetic. May be some iron particles that went into the lamp during the manufacturing process. Have seen it happen. But probably some excessive mercury in the tube. But worth a try! If they are iron particles, you can make yourself a clear tube by scratching off the phosphor.

New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.
We shall reinforce ourselves with good old full mercury t12s and HIDs made to surpass one's life, and give them all the middle finger ;

I have one of those preheat Benjamin fixtures that looks like yours. Really well built vintage fixture. The unique lampholders caught my eye.
