When glass is heated to a certain point it becomes easy to shape. It can be bent and shaped into many ways.

Its an amorphous solid. When the glassblower blows into the glass, it expands just like a balloon. Crystalline solids can't expand like that because their atoms are held together in a rigid lattice. But amorphous solids have many of the proprties of liquids and can flow past each other, allowing the glass to stretch like the skin of a balloon.
Glass is heated in a furnace until it begins to flow. It can then be blown or molded into shape.
A physical change; you're turning the solid glass into a semi-liquid molten state, forming it into a desired shape, and then allowing it to cool and harden.
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
A flat piece of glass. Also, any lens where the shape of the convex part matches the shape of the concave part. An example would be a flat piece of glass bent over a sphere.
This depends on what the materials are. If it is glass, for example, then a glassblower heats up glass and blows it as it cools to create the form and design they want. Metal vases are made from molds, and ceramic vases are made using a spinning wheel to quickly and evenly shape the material.
Jars are made from glass. Glass is made from sand. When sand is heated over 1000 degrees it becomes a liquid. It is then moulded into a shape while it is hot.
It is a plastic that cant be heted again after is been heated and been put in a shape.
