It's a thing. It has a name and you can buy it. It's in brake pads and other friction materials, gaskets, cutting wheels, and apparently rope. It is in the air i breathe and on my clothes.
I know (if you read the fine print) you're not supposed to breathe it, touch it, or wear your clothes home after exposure.
So what is it? Well, it's definitely not asbestos. It says so right in the name.
The tests I took after lunch today conclude that it's 38% caramelized ketchup, 12% crystalized catsup, 27% natural and artificial flavorings and 17% glycerol ester of wood rosin, with less than 2% soylent green.
