What gasses can pass through ceramic? Which ones can‘t?What kind of diffusion would a solid ceramic filter be used for?
one ceramic has a hole and the other one doesn't.
I don't know which I like more: the fact that a group called Potters for Peace actually exists, or the fact they seem to be quiet superheroes. Specifically, they make a ceramic water filter which, it would appear, is high-tech (colloidal-silver-saturated earthenware), low-cost, easy-to-use and filters out approximately 99.88% of most water born disease agents. They also make energy-efficient kilns. It makes me inexplicably happy to know that the potters are throwing down for sustainability.
