Glass pipe are usually one-of-a-kind sort of thing, but blowers will frequently repeat popular designs and patterns. A glass piece can run from five, or even up to hundreds of dollars depending on the amount of color and work the artist puts into the piece. Glass pipes come in; Cliliums, bubblers, bongs --ooops, Don't say the B-word-- I mean "water pipes", color-changing, and uh, almost every imaginable shape. It's up to the glass blower to decide what their skills and imagination will allow.

Common names for styles and patterns blown into pipes.

Double/triple blown - Color and design is inside a thick clear glass coating.
Inside out - Color appears on the surface.
Fritz - Crazy, random speckled, dotted pattern.
Rake - Lines dragged across the pipe.
Cord - Thick lines of decorative cording made from a pre-blown kane.

Color changing?
To give glass its color it undergoes a process called fuming. Metal alloys like, silver and gold, are mixed into and heated to vaporizing point. Entrapping the ions in the glass, giving it the tinted hue that's best viewed with a build up of resin in the pipe. Giving the color-changing pipe the name, the color doesn't change but becomes darker when more resin collects in the pipe.

Cleanliness is next to godliness
A clean glass pipe will provide a pure tasting hit up until point it becomes filled with resin. On the other hand, a metal pipe will have a metallic tinge up to the point it becomes dirty. After that point, any dirty pipe is considered seasoned and will taste like whatever has been smoked out of it. Glass also, is the easiest to clean compared to wood, but there is not as much difference between metal and glass. Wood will add a nice taste, metal is durable and can stand up to the rigors of life, but glass is by far the cleanest toke.
