I was thinking of the RCC tiles, probably should have considered that the white ones would just be health problems city. But the carbon fibers in the RCC ones are bound pretty completely in graphite, so from all the reading I just did (please help me I desperately need a job all this free time is going to kill me) it should be safe to eat those so long as they’re not reduced to, say, a fine dust. Ground down to the consistency of cornmeal though, I can’t find anything that indicates it would be a particular risk?
