Sorry, I've been gone for a week. Here's the code for tha glaze. I used the
blobbing technique, but reversed part of it to make a smooth csg difference
operation.

#declare Thr=.0000001;

isosurface{

function
  (1+Thr)
  -Thr^(sqr( x^2+z^2-.6 )+.7+sqr(y*1.8)+cub(noise3d(x*4,y*4,z*4)/5))
  +Thr^((y+.8+noise3d(x*4,0,z*4)/4)^2)

 threshold 1 sign 1
 contained_by{box{<-1.1,-.5,-1.1>,<1.1,.35,1.1>}}
 pigment{rgb<.6 .5 .2>}
 finish{phong 1}}
}
