Help with name of technique used?

[tam bam]

I aquired two Franco Moretii doves about 6 to 8 months ago. I would love to find out more regarding the technique that was used in the pieces, if anyone could help me out on the board. The heads are a dark green and as your eye looks throughout the rest of the body the green gradually gets lighter. The pieces are really made well and the pictures do not do them justice. You can feel and see the intentional indentions made by the glass blower where the wings are suppose to be. The pieces are signed by Franco Moretti as well.

Here are pics of the pieces. They are both a like, except one is slightly bigger than the other.









Thank you.

Tam Bam, I've never seen a name for the technique, though I am sure it has one. The only way I've heard it described is "color fade to clear" (or shade to clear). I would also like to know if the technique has a name.

I was reading an article on Stephen Fellerman yesterday. The article mentioned that he started out doing graduated colored pieces. Maybe there is not a name for the technique beyond the terms commonly used. (The Italians probably do have a term that we don't know -- they have a name for everything! )
