I just got back from eating sushi and it looks identical. That's what prompted me to upload the video. I was thinking about that call the whole time I was munching down on my flying fish and smelt eggs:laughing:. The smelt eggs are orange and the flying fish eggs are black. It looks just like the stuff coming out of the faucet.
I don't think that is zeolite. Ion exchange resin is one thing, zeolite is another.
This isn't my area of expertise but I think IER is a polymer that has extremely polar covalent bonding sites for ion to bond to which is what allows the ion exchange process to take place. Zeolite is sort of a "molecular filter" it has pores that are so fine that large molecules can be trapped by them. Kinda like an RO membrane but the pores aren’t as small.
I could be wrong about that though. Time to google.......
