<p>[QUOTE=&quot;Bronwen, post: 2289554, member: 5833&quot;]It&#039;s not true of everything.&nbsp; I think maybe the material has to be porous.&nbsp; Pieces I have that are made of antler that retain most of the original material bounce the light off their outsides.&nbsp; Little pieces made from the core of the antler soak it up.&nbsp; A piece made of &#039;fossil&#039; walrus tusk barely changes color.&nbsp; Stone &amp; whole shells reflect.&nbsp; On helmet shell cameos, the shiny brown background shines back purple while the white figures are only faintly lavender. Celluloid seems to take up the light to some degree, going sort of brown.&nbsp; One Celluloid cameo I have looks whiter than in ordinary light.[/QUOTE]</p><p><br /></p>
