Take a look at this celadon incense burner.

The photography is wonderful, but wouldn't you love to hold it in your hand?
How the heck does he get those incredible plates of crystals?
If you've been to this site before, you know what great ceramics are here,
but check out the new arrivals page.
I love to start the day looking at beauty. Most often wonderful natural
scenery does it for me, but vessels such as this fill the bill too.
Cheers, Linda

Dear Linda;
Those are not crystals, they are conchoidal fracture planes which come
from a thick application and a recipe that encourages them. They are
pretty, indeed.

Linda,
Believe it or not those plates of crystals are a very easy effect to
achieve. Try starting with 90% Custer spar and 10% whiting. Apply it real
thick 5mm or more. The blue colour in the samples you show comes from the
clay body mostly. If you are working on a white stoneware/porcelain you can
add some yellow ochre.
Try it - you will get it in a few times with the exact basic recipe above or
with some minor adjustments.
peace,
rod

Thanks Hank.
That makes sense and since I've been looking at it daily, drooling actually
on my keyboard, I was beginning to see that they weren't like crystals I was=
familiar with. And thanks for the new word; gotta go look it up.
Here's one:
A mineral's habit of fracturing to produce curved surfaces like interior of
a shell (conch). Typical of glass and quartz.

ADJECTIVE: Of, relating to, or being a surface characterized by smooth,

Hank,
Actually they are non-conchoidal fractures. ;)
Conchoidal Fractures - Have a circular pattern in their break are much like
broken bottle glass. i./e Obsidian
Non-Conchoidal Fractures - They have no directional cleavage planes or
swirls in there structure. i/e Quartz.
Which explains why high feldpar glazes applied thick develop non-conchoidal
fractures - it's quartz nature ;)

Dear Linda;
See, you weren't far off with your reference to obsidian. I imagine=20
that high silica and a body with a different expansion coefficient=20
would do the trick with concomitant fiddling..
Rained in LA hard last night! So that's over with and won't spoil=20
