II. The Scientific Reading
What the lattice actually does.
Mugglestone, or tiger iron, is a banded metamorphic rock composed of alternating layers of red jasper, silver-grey hematite and golden tiger's eye. It formed in Precambrian banded iron formations of the Pilbara region of Western Australia, where fibrous crocidolite has been silicified into tiger's eye between iron-rich bands.
