Clay

Transcript:

Sarah: I want to play with the material reducer a little bit more. So we've used it on other rocks. We've used it on our quartz, and we've seen silicon and oxygen. We've used it on diorite and we've seen silicon and oxygen, and then right now I have some... well, there's some sandstone -- silicon and oxygen -- it's made of sand, but we have this terracotta here, and that's what our walls are made up of, and in the game you, get it by drying out clay, and if I put terracotta in the material reducer, I get something very different from what we've seen before. So I've got silicon, aluminum, iron, magnesium, calcium, and oxygen, and this is the same thing I get if I put wet clay in here. So do we want to talk about that, and why it's so different from all of the other stuff we've been putting in here so far? 

Kim: Sure. So, I mean clay is just really a fine-grained rock that's made up of minerals that have all of those elements in there, so the serpentines, and the micas, and the complex minerals that are maybe a little bit more complex than quartz. So we get into the aluminums, we get into the irons. The iron is actually what's giving it sort of that red color that you see, that rusty red wall that is in your um in your world. And magnesium, calcium, those are very, very common clay minerals, for sure. Elements, for sure, to makeup clays.
