Kobachi (small bowl).



I love how gravity merges a melting glaze into another.
The blue glaze inside this bowl has a lovely depth when held in the light. Unfortunately it really needs to be held in person to see.
I continue to be amazed by the nuka (white) glaze. It has 33% wood ash (saved from my studio fireplace over Winter) this glaze has a solid white obtained from the ash and some lovely yellow specs from what must be little bits of iron (I know it's from the course black bits of ash). The other ingredients are Silica_33% Potash Feldspar_33%.
This bowl along with some others is on its way to Planet furniture in Sydney. If your in the area perhaps drop in and have a look. 
Planet also has a great selection of other ceramics.

Hi Andrew, the blue on this bowl is stunning!
I was really happy with the nuka recipe- I put it on the rims of some porcelain bowls that were fully glazed in temoku and they went through the wood fire I mentioned. Really beautiful combination. Thanks for sharing Lyn Cole

Thank you so much for adding 'nezumiiro' to your blogroll, Andrew. That's ...quite an honour. Wishing you a happy new year and hoping for a lot of your beautiful works in 2012. Greetings from wintry Europe. t

Lyn, The blue glaze has a little bit of iron oxide in it. That's the trick for a richer blue I think.

Tamara, I love your blog 'nezumiiro'. How could I not list it.
I wish I could be in wintry Europe.
We had a dust storm today. The light went yellow, and I could not keep my eyes open, and the wind tried to rip the roof off.
Have not seen that kind of weather tantrum for years. And they're saying this Summer is going to be a hot one, not happy (a little scared).

lotta, Thanks for starting my year off with an award. Happy New Year to you too.

Hi Andrew, I too think the blue bowl is stunning. I've made a note of the Nuka (white) glaze recipe which I will try with my own wood ash - mostly sweet chestnut here in rural France with some oak. It will be interesting to see the results. I am new to your web site so haven't seen the blue recipe. have you given it before?
Love your pots. Best wishes Roger Bailey

Hello Roger,
Thank you for your comment.
I've made the Nuka glaze with both Ash tree and Iron bark (Eucalyptus). With no discernible difference. I do see a difference between porcelain and stoneware. So suggest clay body does give up some material to the glaze, as is the nature and beauty of high firing.
I would love to see images of your results.

The blue glaze is as follows:
WHITING-500
KAOLIN-500
SILICA-950
POTASH FELDSPAR-625

COBALY CARBONATE-50
RED IRON OXIDE-50
