Default Brewing Properties: Porcelain vs. Zisha

...but residues in those little holes can react slowly with air
and other things, absorb odors from the air, and otherwise store a lot of
unintended flavor. Adsorption (note the d vs. b) onto clean clay surfaces is
a dramatic, so a room with a little garlic, onions, fresh paint, soap, or
anything else smelly is likely to load tens of micrograms (i.e., a lot) of
smelly stuff into the pot to be released at varying rates into the tea.

That's it! I give up.
So maybe *that* was Luk Yu's secret recipe?

Default Brewing Properties: Porcelain vs. Zisha

Oops my misspelling. It s/b eddy. It's the scientific name I give to
the 'agony of the leaves'. There is an eddy from heat convection of
the water causing a viscosity at the surface of the leaves for
leaching. Different tea pot materials cause different eddies which
changes the viscosity at the surface of the leaves. If you had xray
vision the agony of particular leaves in a clay teapot would be
different than porcelain. I used a glass pot for so many years I
could tell ideal brewing time just from the visual clues of the leaves
in the infusion for any given favorite tea. The other thing I like
about glass it adds nothing to the taste which makes it an excellent
reference standard for comparing tea taste to other pots. My love
affair with glass pots came to an end when one shattered in my hand.
I broke other tea pot materials but you're not going to cut yourself.
The other day I put a lawn mower pebble through the exterior pane of a
double glass patio door slider. It started from the chip break and
continuously fractured for a couple of hours till the pane fell out.

It's nothing new to me that the same tea taste different enough in
teapots of different materials. In my case, blacks in stainless
steel, oolongs in porcelain, and greens in clay. There are other
factors such as size, glaze, eddie viscosity.


Jim,

Who's eddie?
Or perhaps I should ask, What's eddie?
Eddie viscosity?

It's supposed to do that. Tempered glass breaks into little pieces instead
of dangerous big ones. Too expensive for teapots, alas, and there are some
engineering diffculties.

It's easy enough to make chemically tempered glassware, though. Lightbulbs
treated this way don't break when dropped on a hard floor - quite amazing.
Wonder if there's enough market to make the product?

I can empathize with that pane of patio door. Sounds like my life sometimes:
Slow, but inexorable and irreversable shattering.

Thought they imploded like TV picture tubes. Do they still have TV picture
tubes?

Drinking Rou Gui Wuyi Oolong, a yummy and joyful tea, but ya gotta use lots
of leaf and really hot water, and a minute or so of steep. Got this one from
TeaSpring. I understand that of all their Wuyi Oolongs, this is the only one
from young trees, but still excellent balance with just hints of fruit and
flower showing through the warm rich round and friendly light wood and
custard of it, true and balanced from aroma to aftertaste.

Listening to Bob Marley Jamming. Joyful as the tea. A perfect mating.

The window replacement shops have thicker thumb and forefinger
calluses than my local tea shoppe owner. The total glass pot is
almost a dinosaur. If I use glass it is a French press with plastic
cradle.

You need to listen to classic country music. One time a Jamaican
offered me some ganja and I thought he was talking about gong cha. I
wasn't disappointed.

If you want to start in country first listen to the women such as
Patsy Cline followed by Tammy Wynette both who could sing the paint
off the wall. Ganja made me comatose.

Ganja? What's ganja? Don't answer, just joking. Ever hear of Bang?
Obviously not, you're still walkin' and talkin'. So, what classic country do
you recommend?

Once upon a time in Quetta...but that's a story for another day.

Drinking Bai Mudan and listening to Lonnie Johnson this fine morning.
