Not quite was I was going for, but after numerous searches I found Friedrich A.


After some tweaking:

#declare P_cells = pigment { cells scale 1/10 }
#declare dark_char = pigment { rgb 0 }
#declare ember = pigment { red 1 }
#declare P_clear = pigment { color rgbt 1 }

#declare Burning = texture {
pigment {
   pigment_pattern {
     planar
     rotate -90*z
     color_map { [0.1 White] [0.15 Black ] }
     scale 1
     turbulence .2
   }
   pigment_map {
     [ 0, P_cells ]
     [ 0.85, dark_char ]
     [ 0.90, ember ]
     [ 1, P_clear ]
   }
 }
} // Burning

The pigment_pattern is the solution I'm looking for.
