My previous render finally finished and now I could make a new SSS test,
this time with textures. The edges between red and white are actually
completely sharp. It's the fact that the light enters the object that we
can see some smooth edges. My trick was to use multiple media statements:
one with scattering media (type 5, eccentricity -0.2) with extinction
turned off, the other with simple absorption media. I'll make the source
available if I can clean it up some more.

One more thing. The texture itself was a density statement in the first
media.

This is a really interesting effect...
I actually did something sort of similar a while back - I was trying to
simulate an actual rock I have on my shelf. Parts of it are totally
transparent, and parts are milky white. It's not quite the same thing as
you're trying to do, but now you've jogged my memory maybe I'll post it...
This is the first time I've replied, but I've been watching your experiments
on this stuff with interest - keep up the good work ;-)
Andrew.

I'm not sure this looks too real / logical ?
Considering the angle of light.
