I've been thinking about rendering ceramics for a while, and I finally had time
to start playing with some textures. This is the fired, unglazed ceramic texture
- there's still quite a lot that could be improved, but it's at least looking
plausible to me.

The glaze will be much harder. The crazing from the glaze shrinking at a
different rate from the clay when fired is probably not possibly in SDL, which
is a shame.

The best way to do glaze would be physically with an actual layer on top of the
clay using media, but that presents a modeling problem I don't want to solve.
Perhaps you might be able to do it with an enormous number of very small blobs,
but that would probably be extremely slow to render.

Cheers,
Edouard.

   Looks perfect for me... in fact, I would have recognized perfectly this
kind of ceramic even if you didn't tell us what it was (it's very common
around here).

   Perhaps a clever usage of crackle will do... but looks very difficult, no
doubt.

It's anyway a fantastic (pov)shot! I'm not sure it needs the glaze...

or with facets. I got some acceptable results.

This is a VERY good texture. It looks glazed to me because of the speculars. 
It is not the shiny glaze of course, but the one I personally prefer, a 
discrete one which you see on stoneware utility pots for instance.

You may try an extra texture layer with a semi-transparant pigment, a 
specular finish, and a normal using either one of the crackles, or facets.

Great texture, once again!

I really like the material! It looks very attractive to the eye.

yes i think crackle with poly_wave and reflection may get close  also 
black hole warp to vary the scale

It looks great already!

Very convincing. It looks like ceramic at first sight.
