To bend glass you need to heat it, bend it, then allow it to cool in a slow and controlled manner. If you're talking about glass beads it's a different story, although the cool slowly still applies.

Yes, light bends when it travels from air to glass due to the change in speed caused by the different optical densities of the two mediums. This phenomenon is known as refraction and is responsible for effects such as the bending of a straw in a glass of water.
When light enters glass, it bends due to the difference in the speed of light in glass compared to air (refraction). When the light exits the glass back into air, it bends again, this time away from the normal line. This bending of light is due to the change in the speed of light as it transitions from glass back to air.
It bends in water or a magnifying glass.

The blue light is refracted more.
Curved glass bends light rays due to refraction, where the change in speed of light as it passes from air to the glass causes it to change direction. The curvature of the glass surface also plays a role in how the light is refracted, which can be used in technologies like lenses and curved displays to manipulate the path of light.
Nothing but shape. A lens is just a curved piece of glass, as well as glass being a straight lens. A lens bends the light while glass does not*. *Assuming the glass is straight
Because the surface of the bottle is curved - which bends the light passing through it - just like a magnifying glass does.
The ray of light gets refracted. Depending on the medium it is entering, it will bend either to or away from the normal. For example, if it is entering a glass block from air, it will bend towards the normal, and if it leaves a glass block and enters air it will bend away from the normal. The amount the ray bends depends on the angle of incidences and the refractive indices of the two mediums, and are governed by Snell's Law.
