Prusa Glow-in-the-Dark Filament Abrasiveness

I've read in a few places glow-in-the-dark filament is abrasive. Just how abrasive is the Glow-In-The-Dark filament Prusa sells? Can I get away with printing a few hundred grams without killing my Nickle plated nozzle?

off hand I would say yes, I have printed lots of glow in the dark and iron filament and it hasn't been too bad. and that's with brass nozzles

I have a Prusa,therefore I research.

Well - the data is in. Nickel-Plated Copper and Glow in the Dark is a very bad combination. Especially bad if you use GRID infill.

From installation to last print using up about 500 grams of Glow the nozzle was seriously worn. 1st Layer adjust had to be changed from -0.650 to -0.850 to get 0.2mm first layers again.

When questioned: E3D says "do not use the Nickel-Plated heads with any abrasive material." I'm not sure I'd use them again with any material unless I had to have the high temp properties E3D claims. Even then I'd expect the life of the nozzle to be less than 1kg of material.

ps: some more research. Zinc Sulfate is the glowing additive material. It's hardness is about 1500; silicon carbide (sand paper) is only 2500. For comparison, brass is about 150 on the scale, hardened steel about 1000.
