SAND GLASS Meaning and
Definition
-
A sand glass, also known as an hourglass, is a device used to measure time. It consists of two glass bulbs or chambers connected vertically by a narrow neck or tube. The chambers are usually made of transparent glass or plastic material and shaped like inverted cones. The neck or tube in between is narrow to control the flow of fine sand or sand-like particles.
The sand glass works on the principle of gravity. Initially, the sand glass is set with one chamber positioned upside down and the sand flows from the upper chamber to the lower chamber due to the force of gravity. The amount of sand in the upper chamber indicates the measure of time. As the sand flows continuously from the upper to the lower chamber, it gradually fills the lower chamber, indicating the passing of time. The duration it takes for all the sand to pass from one chamber to the other is usually fixed at a specific period, varying from minutes to hours.
Traditionally, sand glasses were used in various domains, such as maritime navigation, culinary practices, and scientific experiments. Today, they are more commonly employed for decorative purposes, as reminders for short durations, or as educational tools to illustrate the concept of time. The sand glass remains an iconic and aesthetically pleasing device, capturing the essence of time-keeping in a simple and classic form.

Etymology of SAND GLASS
The word "sand glass" is derived from the combination of the words "sand" and "glass".
The term "sand" originates from the Middle English word "sande", which can be traced back to the Old English word "send" and the Proto-Germanic word "sandam". These Germanic roots connect to the Old Norse word "sandr" and the Proto-Indo-European (PIE) word "*bhsam". The PIE root "*bhsam" meant "loose material" or "grains", which eventually evolved to specifically refer to granular material.
The word "glass" comes from the Old English word "glæs", which itself shares a common Germanic origin with various related words in different Germanic languages, such as Old Norse "gler" and Old High German "glas".
