Huh people really don’t think about actual materials anymore. I was hoping for stuff like: metals, concrete, plastics, ceramics, biologicals

Well, I was starting off with solid, liquid, gas ... plasma(?), empty space(??). OK, I can't get to 5 and keep it folks(onom)y, but the first three seem like pretty commonsense categories even though also science-y. Unlike the alchemists by 'materials' do you assume solid?
