EHLO

I have some computer generated .INC files with this type of object :

#declare essai = object {
union {
sphere { <0.000000, 0.000000, 0.000000> 0.300000
    pigment { color <0.500000, 0.500000, 0.500000> } }
sphere { <0.361449, 0.271070, 0.291044> 0.251914
    pigment { color <0.000000, 0.000000, 0.000000> } }
}

In the main scene, I try that :

object { essai finish { reflection 0.9 ambient 0 diffuse 0.1 } }

And,  noway to have all my little bubbles be a mirror...

It just can't work.
Any texture that is explicitely applyed to any object are never replaced 
nor layered over by any texture or finish applyed to the CSG object.
object{sphere{0 1 pigment{rgb<1,0,0>}} pigment{rgb<0,1,1>}}
Will result in a pure red sphere, without any hint of cyant.

If you where to add some untextured object, then, that object will get 
reflective.

A possible workaround would be as follow:

#declare O_Default = texture{}
  // Save the original default texture.
  // An empty texture block always return the current default texture.
#default{finish{ reflection 0.9 ambient 0 diffuse 0.1 } }
  // Set a new default texture with the reflection that you want
object { essai }
  // Place your object
#default texture { O_Default }
  // Restore the original default texture
