Cone:
In common usage and elementary geometry, a cone is a solid object obtained by rotating a right triangle around one of its two short sides, the cone’s axis. The disk swept by the other short side is called the base, and the endpoint of the axis which is not on the base is the cone’s apex or vertex. An object shaped like a cone is said to be conical.
Cylinder:
In mathematics a cylinder is a quadric, i.e. a three-dimensional surface, with the following equation in Cartesian coordinates: This equation is for an elliptic cylinder. If a = b then the surface is a circular cylinder. The cylinder is a degenerate quadric because at least one of the coordinates (in this case z) does not appear in the equation. By some definitions the cylinder is not considered to be a quadric at all.

ALES LOMBERGAR is one of the few artisans in Europe who still practice the ancient art of glass acid etching which flourished in the late 19th century. Decorations are applied with resin resists by hand and then exposed to acid baths, with no machinery used. More information here.
