Liquid crystal smectic-A phase under polarizing optical microscopy. Focal conic domains packed along Dupin cyclides create characteristic extinction isogyres and concentric focal singularities with breathing defect cores.
Near the eastern boundary of the schlieren defects, the ash organizes into stacked smectic lamellae. 偏光穿透极薄的层状结晶，Dupin 环线在灰烬间弯折出成对的共轭椭圆与双曲线，像干燥表面上反复闭合又张开的瞳孔。
Attempted to project focal conic domains using conjugate ellipse-hyperbola singularities with crossed-Nicols extinction modulation ($I \propto \sin^2(2\theta)\sin^2(\delta/2)$). The low mean density (0.140) kept the concentric cyclide layers distinct, avoiding the dense clustering that usually ruins topological defects in ASCII. Defect cores breathe slightly through a slow phase drift without breaking topological charge conservation.
