Comments:Published PDF date : Northern Song early 12thC Room 95 label text:PDF 61Bottle with copper rim mountSong dynasty authors describe the Ru glaze as containing powdered agate which was mined locally to the Qingliangsi kiln site. The fine bluish colour of this glaze is in fact due to dissolved iron-oxide, together with very low levels of titanium dioxide. Titanium has a yellowing effect on glaze-colour and usually encourages a green tone in most Chinese celadons. A yellow cast can also come from coal-firing but the Ru ware potters seem to have practised wood-firing, even though most north Chinese kilns at this time were fired with coal. Archaeologists discovered a related slim-necked vase with flaring foot and mouth in the Qingliangsi kiln site.
