Years ago, I made a celadon texture. I was curious to see how it would 
appear with SSLT added.

The superellipsoid has James Holsenback's marble texture (see Paradise), 
also with SSLT.

Or, finally.

For those interested in the texture:

//-----start code
#declare TdG_Celadon =
material {
   texture {
     pigment {
       bozo
       pigment_map {
         [0.0 color rgb <0.762025, 0.883775, 0.762025>]
         [0.2 color rgb <0.855688, 0.935979, 0.855688>]
         [0.5 color rgb <0.728519, 0.896481, 0.728519>]
         [0.8 color rgb <0.937467, 1.000000, 0.937467>]
         [1.0 color rgb <0.548054, 0.722746, 0.548054>]
       }
     }
     normal {
       crackle 0.5 solid
       warp {turbulence <0.1, 0.1, 0.1>}
       scale  0.1
     }
     finish {
       diffuse 0.6
       specular 0.5
       roughness 0.005
       conserve_energy
       #if (SS)
         subsurface {translucency <0.45, 0.38,0.33>*0.5}
       #end
       reflection {
         0.01 , 0.2
         fresnel  on
         falloff  1.0
         exponent 1.0
       }
     }
   }
   interior {ior 1.5}
}
//-----end code

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.
