Pronunciation: [wˈɔːtə ɡlˈas] (IPA) 
The word "water glass" is spelled with a silent "e" in the first word and pronounced as /ˈwɔːtər ɡlæs/ in IPA phonetic transcription. The "w" sound represents the initial consonant cluster, "wa," while "a" and "e" form a diphthong sound /ɔː/. The second word, "glass," is pronounced as /ɡlæs/ with a hard "g" sound and a short "a" followed by a double "s." This term refers to a glass container used to store water or other liquids.
Water Glass, also known as sodium silicate, is an inorganic compound commonly used as a binding agent for various applications. It is a translucent or clear liquid with a high viscosity, consisting mainly of sodium and potassium silicate salts dissolved in water. The term "water glass" primarily refers to a solution that contains sodium silicate, one of the most widely used forms.
Water glass has multiple uses due to its adhesive and sealing properties. It can be used as an adhesive to bond porous materials such as paper, cardboard, woods, and certain fabrics. Its adhesive capabilities make it suitable for various crafts, bookbinding, and box manufacturing. Additionally, water glass can serve as a sealing agent for concrete and masonry, preventing the entry of water and other liquids.
This versatile solution also finds applications in the preservation of eggs, acting as a coating on the shell to extend their shelf life. It can form a protective barrier, preventing bacteria from entering through the porous shell. Moreover, water glass is sometimes used as a fire retardant in textiles and as a corrosion inhibitor in coatings for metals.
While water glass offers advantageous properties, it is important to handle it with care, as it is highly alkaline and can cause skin and eye irritation. It should be stored in a cool and dry place, away from flammable substances, to avoid potential hazards.
Soluble glass, silicate of sodium or of potassium, soluble in hot water but solid at ordinary temperatures; used for fixed dressings.

The word "water glass" is actually a compound noun, composed of two words: "water" and "glass".
"Water" originates from the Old English word "wæter", which has Germanic roots. It is related to the Old Norse word "vatn" and the Gothic word "wato".
"Glass", on the other hand, comes from the Old English word "glæs", which is derived from the West Germanic word "glasam".
Hence, the etymology of "water glass" can be traced back to the blending of these two Anglo-Saxon words referring to the transparent, liquid substance called "water", and the material "glass", respectively.
