I would think that if graal technique was used it is a very strange result. ![Smiley :)](http://www.glassmessages.com/Smileys/classic/smiley.gif)
Now that I see the face, (doh) I can understand why you say Graal. But without more information, I still think the face looks more like torch work with canes than graal technique, using a method similar to that used by Siddy Langley, Richard Jolley or William Bernstein as well as myself.
