vandglas

Vandglas, also known as water glass or sodium silicate, is a chemical compound with the formula Na2SiO3. It is a soluble silicate, meaning it dissolves in water. Vandglas is typically produced by fusing sand (silicon dioxide) with sodium carbonate (soda ash) at high temperatures. It can also be made by reacting sodium hydroxide with silicon dioxide.

In its solid form, vandglas is a glassy, amorphous solid. When dissolved in water, it forms a viscous, alkaline solution. The concentration and alkalinity of the solution can be adjusted by varying the ratio of sodium oxide to silicon dioxide.

Vandglas has a wide range of industrial and domestic applications. Industrially, it is used as a binder in detergents and soaps, as a component in adhesives, and in the manufacturing of ceramics and refractories. It also plays a role in the production of silica gel, a desiccant. In construction, it is used for concrete hardening and waterproofing.

Domestically, vandglas has been used historically as a preservative for eggs, creating a seal that prevents spoilage. It is also found in some cleaning products due to its ability to emulsify grease and oil. Its alkaline nature makes it useful for cleaning ovens and grills. Due to its versatility and relatively low cost, vandglas remains an important chemical in various sectors.
