Woweee Chamekke, that is gorgeous. Here's hoping some of our resident artisans decide to explore that glaze!
***This organic blend is earthy & spicy, with a fragrant aroma & smooth flavor to captivate the senses. Naturally sweetened in the Kentucky sunshine & infused with natural energy. Equally delicious when served piping hot or crisply chilled.***
Wow, that is stunning Chamekke! And the perfect shape too!

This is a zinc silicate (orthosilicate) glaze. In its naturally occurring form, it's often known as Willemite, but the glaze too is often given that name. I gather that it can be a bit unpredictable; Katy's first effort to produce a yunomi with this beautiful iridescent glaze had exactly two rather tiny crystal "blooms" on it - no more! No doubt it was a bit of a challenge, since the surface area was quite limited compared to the usual bowls and vases that potters seem to favour.kymidwife wrote:Woweee Chamekke, that is gorgeous.

There's a webpage here devoted to the work of potters who use this distinctive glaze.
I became interested in this glaze after I bought a (mass-produced) gaiwan with a similar glaze - made by Eilong of Taiwan and sold by Hou De:
Unfortunately I broke the bowl shortly afterwards, and to my dismay I found that neither TeaCentre nor anyone else was still selling the gaiwan - although you can find some vendors who sell a similar set of spouted gaiwan and two cups.
P.S. Very informative Powerpoint slideshow on Willemite glazes here:

Chamekke, that is gorgeous!! I actually like your new one over the one you broke. Bit of a jammy outcome there 
Many of the folks on that website echo the sentiment that the glaze is very tricky to work with, but some of the pieces are very stunning (a lot of them were just a bit too gaudy for my tastes). I loved the article about the science behind the crystals. Geeking on glazes
Cheers and enjoy!

well..halfway a local potter here in the knoxville tn area.. the glazing/firing was done this weekend at the annual pottery show...by me 
...I still am going to have to seal the inside to make it food safe though as it was a Raku firing. it did turn out pretty cool though I thought! had to get a a nice thick glaze on it to make it crackle like it did
