The unofficial/official HAGI topic!

Kymidwife,

Wow yours has progressed quite a bit. There is this thing called the 7 stages of hagi which may catalog the typical stages a piece goes through.

In my mind from what I have seen, while each piece is different (probably true for pieces in the same run) but the general progression seems to be inside, outside, then color change of the clay exposed in the foot. With possibly Crackling being the first thing that happens (if it did not occur in the piece naturally).

Those in my mind are the first 3-4 stages of hagi, and I'd love to hear what people think may be the next 4-3 stages.

But Like I said each piece is unique, my Sansai has fairly even crackling and crack staining on the entire inside. But Due to seeing the effects in other pieces, it might be that the glaze on the bottom inside of your piece is thinner. As I actually have a piece from Deishi that has a very thin glaze on the inside, and despite many uses the inside shows little effects, though there are slight stains in cracks on the outside.

I do not know the physics of glazes, the clays, or their interaction when it comes to heat expansion and contraction, but two things seem possible:

Thin glazes either handle the expansion and contraction of the entire piece better as the clay and glaze undergo the temp changes at roughly the same time so there is less of a need to crack.

OR

In the thiner glaze after a rinse or rub it cleans out the tea close to the surface of the glaze in the cracks, but with thicker glazes it gets stuck deeper in, but is still quite visible.

Like I said, each piece is unique, and thats part of the attraction of Hagi yaki.

ky - great photos!
My response is that I just think the crackling on your san sai wan is gorgeous. I can hardly wait until mine looks that good.

Whatever the science is behind the crackling process, I really love this piece! My Deishi white pieces are very dear to me too, as they were my first Hagi... and they have crackled beautifully too, but in a totally different pattern/process and MUCH slower than this piece. This one has literally only held tea 2 or 3 times.

In answer to previous questions... I did pretreat the piece before its first use, soaking it in a boiling/simmering bath for a couple of hours... but it was completely submerged the entire time. And in regard to prewarming, I prewarm it before each use by filling to the brim with very warm water.

Ours is not to question why, I suppose... and now, I am thinking I really MUST get out my matching kyusu and give it a bath so the crackling will match.

Oh, and here's my Seigen Blue Tebineri Yunomi... finally got a photo of it as well...

Wow, that is awesome. I wish I had bought one.

As far as I know you still can:

Yes Sarah, you must break out the kyusu for the matching effect!

Beautiful Blue Tebineri!! Nice pic.

Still can! http://www.teachat.com/viewtopic.php?f=36&t=11646 PM me ... we may not do another Tebineri SO for some time.

Both the Sansai and the Ao (blue) are really astounding and beautiful to behold and hold ... feel great in hand.

Thanks for sharing the Ao Tebineri with us, great shot Sarah.

Thanks everyone for your comments on my Hagi in Paradise. So far Hagi has been to Kihei, Wailea and Makena. Stay tuned for Lahaina up next. And then the burning question is ... can Hagi survive the Road to Hana?

Love the Hagi in Hawaii pictures...ahhhh, the sun is shining somewhere!

By the way, during a two-week vacation to Hawaii way-back-when, we decided that we wound up "wasting" a day of our awesome vacation on the road to Hana. Hopefully, if you're going to do the "hiway to Hana" thing you will have a great time. I would not take my precious Hagi on that trip!

Hope you're really enjoying your trip...I am surely loving it!

LOVED the Hana drive last time we did it. IIRC, it was at exactly this same time of year, but they had just had a tremendous storm blow through, so we couldn't swim or snorkel anyways. We spent the day on the drive, it was beautiful, sunshine, warm. We had a convertible for the rental. Fantastic!

[edkrueger]

Hmm. It is a bit pricey. I'll just see what comes along later.

Hagi in Lahaina

Just loving the 'hagi in paradise' Vic.
Imagining you reveling in Maui makes me smile (me and my sweety might go there for honeymoon this spring ).
Cheers.

A few more shots of the Hagi blue chawan I showed off in the Today's Matcha thread. I've had this one for a while, purchased from eBay. It's got a gorgeous glaze, but a flat bottom rather than a carved foot. Hasn't altered my enjoyment of it thus far.















Sorry for the poor quality of this last photo... didn't realize it was so blurry until I viewed it on the computer, and by then I was too lazy to reshoot. I just wanted to show size scale between the chawan, the Ao Tebineri, and the little blue wan:



Thanks for looking...

I don't know everything but crackeling is poducted because of a difference of superficial tension between the glaze and the clay. Warm and cold are producting an effect on the glaze that is moving on and on, use after use. Here it seems that the upper of the bowl is more thin then the bottom and that in the bottom the glaze is applied more thickly. Perhpas that's why the upper bowl is more crackled that the bottom. In fact differences thikness of the clay are also a factor that can put the crack in the clay but also in the glaze.

Thanks Ginkgo, that makes sense. I was puzzling on why it was behaving differently than some of my others, when I'd treated it the same way. I really enjoy seeing what happens over time... even more-so now that I know the pieces won't all be predictable and similar in their progression. The thickness of the clay and glaze seems a logical factor in determining how the crackling occurs.

I thought of taking the shot holding the cup out in front of the waterfall, but this seemed safer.
