I have used this technique my self from time to time, however, because the
vessel is defined from two mesh objects, one slightly smaller than the
other, if made of glass refraction does not look correct as there is
'nothing between the inside and outside.
but for an object which only plays a minor role in a scene, it is not
notacable.

I haven't tested it, but I think you can get away with
union {
object{ patch_object_1 texture{...}}
object{ patch_object_2 texture{...}}
interior {...}
}
and have the refraction handled correctly. Yes, patch objects aren't supposed
to work in CSG, but I think this will work anyway based on what I know of the
way POV does refraction.

Well... i found myself in your same condition (sPatch + label image_mapping)
and my quick solution corresponded *exactly* to the one suggested by Nathan
Kopp .
If you want to look to the image i made, here is the direct url:

Feel free to ask me everything about the image, and of course any criticism is
welcomed :)
