Meniscus is not composed of anything its a physical properties due to surface tension of liquids.
It is dependant on the:
cohesive forces - binds similar molecules together.
adhesive forces - bind a substance to a surface.
Water for example in a glass tube the meniscus is U-shaped, we say, that the adhesive forces between the water and glass are greater, than the cohesive forces between water molecule, but for Mercury, the meniscus is curved downward therefore we would say .....
One other thing in narrow tubes the rise of liquids is called capillary action.
A meniscus, but whether it has a positive curve or a negative one depends on whether it wets the glass.
The Meniscus is the name for bubble in the metric system
As the diameter of the container decreases, the meniscus becomes more pronounced. The meniscus may be convex (curving upward) or concave (curving downward). Most of the time you will find that the meniscus is concave. The most notable exception is the meniscus that forms from mercury. When taking measurement readings it is important that the reading is done properly. The following rules must be adhered to: I. Read the meniscus at eye level. Do not read the meniscus from above or below eye level. Significant measurement errors may occur II. Read the bottom of a concave meniscus and the top of a convex meniscus.
You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.
The meniscus rule states that you always measure the volume of a water-based solution from the bottom of the meniscus when you are using a graduated cylinder.

It's called Ya Mum's Panis
Water's meniscus curves up. Mercury's meniscus curves down.
Do you mean is a meniscus always concave? If so, then no. For example, the meniscus of mercury is convex.
Meniscus
meniscus is the level of a liquid in a cylinder.
You measure from the bottom curve of the meniscus.
You measure at the bottom of the meniscus.
Omobranchus meniscus was created in 1975.
