Thanks Mark.  No, nothing missed.  That test render was as far as I took 
things.  In fact I don't think the render even includes the grunge 
effect, that was going to be for a second cut which would have also had 
a nice fabric for the display surface.  But I lost interest as usual. 
Funny, Jaime and others have put fabric capabilities into our hands in a 
way that it wasn't when I did the model.  Really should finish this one 
off. Actually the other necessary component, lighting for such a model, 
has also been improved by the efforts of others including Jaime, and I 
am learning it on my current project, so maybe I can roll it all 
together and make a good final render of that chalice.

That latter I think.

pigment {
   average
   pigment_map {
     #local I=0;#while(I<90)
       [1
         object {
           object {
             k13_texture_
             #local J = rand(S);
             scale <.9+.2*J,1,.9+.2*J>
           }
           pigment { rgb  CHSL2RGB( <70,.12,.29> ) }
           pigment { rgb  CHSL2RGB( <65,.24,.08> ) }
         }
       ]
       [1
         object {
           object {
             k13_texture_
             rotate y*(-10+20*rand(S))
           }
           pigment { rgb  CHSL2RGB( <70,.12,.29> ) }
           pigment { rgb  CHSL2RGB( <65,.24,.08> ) }
         }
       ]
       #local I=I+1;#end
    }
  }
