Summary
| Description |
English: Crystals formed during production of a Song Dynasty “oil spot” glaze on a ceramic tea bowl, as seen in a petrographic ultrathin section under transmitted plane polarized light. The colorless center of the flower-form is anorthite (a calcium-aluminum silicate), which also forms the radiating petal structures. Brown iron oxides have precipitated along the petal edges. Viewed under a Nikon Eclipse 50i POL microscope, captured with a QImaging MicroPublisher 5.0 RTV CCD camera. |
