Sure did. I was wondering if those red hot pixels from before might be purely a
side effect of SSS or if somehow caused by a small amount of reflection in the
texture or external object (floor).
Apparently I never asked about it before, and I can't see any reflection in
either of the marble texture renders.
Not that the other marble looked too transparent to me, like what do I know of
marble in all its possible appearances, but I can see how this one has more
solidness or perceivable larger size compared to that.

Indeed! Did you use the "finish_map" trick?

nope ... it's procedural. the underlying pigment is a single color with
a touch of irid ( also changed irid_wavelength in global_settings to
that color ) for the normal i used f_ridged_mf

I like the brass texture too.
In fact I tried to reproduce it - here is my attempt...
Perhaps you want to correct my mistakes?
global_settings {
irid_wavelength srgb <254,182,89>/255
}
texture {
pigment {color srgb <254,182,89>/255}
normal {
average
normal_map {
[1 bumps
scale 0.0175
bump_size 0.2
]
[1 bumps
scale 0.35
bump_size 0.2
]
[1 function {(f_ridged_mf ((4+x)/0.3, y/0.3, z/0.3, 0.5, 2.7, 4,
1, 1.5, 0)-1.8)*0.5}
scale 0.35
bump_size 0.3
slope_map {
[0 <0,1>]
[0.25 <1,0>]
[1 <1,0>]
}
]
}
accuracy 0.003
}
finish {
ambient 0
diffuse 0.16
specular 0.8
roughness 0.11
metallic
reflection {0.2, 0.4 metallic}
irid {0.07 thickness 0.5 turbulence 0.2}
}
}
