Metallography of an iron age slag showing the matrix with fayalite and wustite and several cavities. Around a large irregular cavity a unknown layered structure is visible.

On #FindsFriday I present a question! This #metallography of a late iron age #slag has an inclusion I cannot identify! The slag contains fayalite and wustite indicating iron #smelting, but what is this layering around the cavity?
