A new purchase, 20cm across the rim, 9cm high.
It doesn't resemble its beautifully-lit photo on the Etsy listing, which showed a bowl of glowing golden yellow with greenish stripes. The reality is a milky tea colour with grey stripes within colourless casing, but it does liven up with the sun behind it, becoming translucent golden brown with yellow threads and 'eyes'.
The reticulated pattern is not formed in the more familiar Ikora manner (quenching followed by dipping into a metal salt solution) but with elongated bubbles and thin ochre yellow threading. The bowl doesn't have the usual foot, but a few patterns were made without, and I assume in those designs there would be the pontil mark you can see in my photo. The glass body has the look, feel and heft of Ikora.
All that said, I'm still not sure my attribution is correct. Any thoughts?
