What are the red cracks? On three dark vessels in pieces 1901–1950, a crusted band or zone splits into fissures, and the splits open onto rust-red to plum tones underneath — like dried mud cracking over embers. 1902 carries the seams across a dark crust band; 1904 cracks wider; 1911 shows the look best across three photos.
The term names the look — rust-red to plum tones opening in the splits — not the cause beneath. The fissures are observed, never characterized as damage. A different fissured look has its own term: fissured crust webs a sandy body with nothing revealed beneath.
