WATCH GLASS Meaning and
Definition
-
A watch glass is a shallow, circular glass dish that is utilized in various scientific experiments and laboratory settings. It typically resembles a small saucer, with a flat, round shape and a slight concavity. The primary purpose of a watch glass is to act as a cover or lid for containers, such as beakers or evaporating dishes. It is commonly placed on top of the container to prevent the escape or contamination of substances during heating or evaporation processes.
The watch glass is typically made of durable, heat-resistant glass material, allowing it to withstand high temperatures without cracking or shattering. Its smooth surface and slight curvature make it ideal for holding or collecting small quantities of liquids, powders, or solids. It also serves as a protective barrier, guarding against potential splashes or spills and minimizing the risk of contamination in sensitive experiments.
Furthermore, the watch glass provides a clear and visible surface for observation, enabling scientists to closely monitor chemical reactions, crystallization, or any changes occurring within the covered container. Due to its versatility and convenience, the watch glass has become a staple in many scientific disciplines, including chemistry, biology, and physics laboratories.

Etymology of WATCH GLASS
The word "watch glass" is derived from the combination of two different terms.
The first part, "watch", originally referred to a small timekeeping device worn on the wrist or carried in a pocket, known as a wristwatch or a pocket watch. The term "watch" can be traced back to the Old English word "woecce", which means "watchman" or "guard". It evolved over time to refer specifically to timekeeping devices.
The second part, "glass", indicates the material used for the watch glass. Historically, watch glasses were made of glass, hence the term. Glass comes from the Old English word "glaes" and the Germanic word "glos", both of which refer to the substance.
Therefore, the term "watch glass" combines the words "watch", referring to a timekeeping device, and "glass", indicating the material used.
