Marble
Marble comes from the marble face in the quarry by your base: each break gives 4, and the face closes up again, so it never runs out. It is hard work, though: it needs Building mastery 7 and a pickaxe.
Marble Plates and the rest of the marble line wait on The Concept of Marble (80 red, 30 blue). It is an alchemy ingredient with three red runes, and studying it costs 5 Science and 2 Faith for 20 red.
