Are you talking about a pipe stem triangle? It's composed of twisted wire running through three clay pipes in the shape of an equilateral triangle. It is placed on an iron ring attached to a ring stand, and is used to hold a crucible over the flame of a Bunsen burner.
A pipestem triangle is made from galvanized steel and porcelain pipe. It is used to support a crucible on a ring when it is being heated by a burner.
To find this you need to imagine the pipe slit straight down and rolled out. At this point what you have is 10 right triangles, with the base of the triangle being the circumference of the pipe and the height of the triangle being the height of the pipe divided by the number of wrappings. The hypotenuse then is the length of one wrapping. Multiply that number by the number of wrappings and voila, you have the length of the wire.

A pipe clay triangle's use is similar to a gauze mat; to steady/hold apparatus on a tripod while usually they are being heated by a Bunsen burner.
USE in the process of heating substances..
A pipe clay triangle is used to support e.g. a crucible on a tripod over a bunsen flame.
A mountain?? Doesn't make any sense!!
I've seen them refered to as "tavern pipes." Supposedly they were kept in the tavern as a kind of community pipe. Patrons could use one of these pipes and then break off a piece of the stem before returning it to the rack. I've also heard that this is not the reason for the long stem, rather it is for the same purpose as a briar churchwarden style pipe. Which is of course a cooler smoking pipe.
