Photomicrography was used to
present the patterns of a Song dynasty
Jian kiln tea bowl. The glimmering yellow
dots that look like stars are feldspar
crystals. The blue areas that appear like
nebulae are comprised of clay and glaze
that are rich in iron. After firing at high
temperatures, they produce two types of
crystals. This ingenious combination
forms the image of a starry sky in the
universe.
