Dear Pin and Adrian,
I remain with my idea that we are too easily surmising that a bottle is carved from solid block. In my opinion a carved bottle is easily identifiable. Even if perfectly polished, the surface structure is different from a normal glass surface. In this bottle for example, if you look at the surface inside the neck you can see a different surface than that of the interior. The inner neck surface has been grinded to make it perfectly round, the rest of the inner bottle not. As for the variation in thickness, remember that by looking at the bottle, the same way we see the picture, you are not looking at a cross section. A light variation in the curvature has a more or less pronounced lens effect, thus showing the thickness bigger or smaller than it is in reality. As you turn a bit the bottle, you see the apparent thickness changing. For example, in that picture if you look the thickness of the glass near the mouth, you will see that in the transparency it seems that it goes almost to zero, while indeed by looking at the top you see that the thickness is relevant there. The image below shows what I mean.
Kind regards
Giovanni
