Plate 17 in the OpenGL Red Book has 24 teapots all rendered
in different 'materials'.
The source code for that program lists all the material properties it used.
(I can't remember where the source for that program is - but I kept the table
of materials handy):
(My apologies for the 'tab' characters)
Material Ambient (R,G,B) Diffuse (R,G,B) Specular (R,G,B) Shininess.
