Where did you learn to get your china so thin. I was never able to get
it less then 1 mm and have it survive. Though to be fair I normally use
standard clay. (my website
http://bytehouwer.nl/visitekaart/en/ceramics.html needs urgently an update)

A well kept secret ;-) Although, looking at your examples, the (white)
compound vases come close to my bowl.

Raku fired, not celadon glazing. Both ancient asian techniques, but
rather different.

I saw a few other raku ceramics on your site if I am not mistaken. One
of my favourite techniques. I am not a ceramist myself but I highly
appreciate the work.

Nice! do you mind if I use it as a basis for one of the materials shared at the
below link?

You have my permission :-) You may even change rgb to srgb in the
pigment. Makes the colour a bit fuller. However, Celadon comes in
several hues.

It is an interesting technique. Problem is that after you reduced the
oxides during firing, they start oxidising slowly during the months
after that.
I made also another set of compound vases (using a 3D printer to create
a mold) those colors are totally different (mostly greens and red) even
if I used more or less the same pigments.
Mainly fired my recent work in a more traditional way. I might return to
japanese techniques when I have objects that are suitable for that.
Perhaps another set of larger compound vases?

That's interesting. I didn't know that but seems logical indeed. So you
never know what to expect in the end. I think I like that :-)

Slight variations in temperatures? in burning times?

This is going a bit OT but... As raku, I particularly like the rougher,
simple objects. They are only simple at a superficial glance though.
