This mosaic is made out of numerous different old cups and plates. There's a large blue marble on the knob of the lid, surrounded by beads, there are lots of different smaller blue marbles round the rim and the mosaic parts are edged with blue mosaic glass. I grouted in light blue and as usual left the beautiful gold edges on the vintage teapot base showing. 

The teapot is about 22 cm tall including the marble on the knob.
