The mineral used for making laundry detergents and glass is soda ash, also known as sodium carbonate (Na₂CO₃).

Here's why:

* Laundry detergents: Soda ash acts as a builder, which helps to soften the water and improve the cleaning performance of the detergent. It also helps to increase the alkalinity of the detergent, which aids in breaking down dirt and grease.

* Glass: Soda ash is a key ingredient in glassmaking. It acts as a flux, lowering the melting point of silica sand (SiO₂) and allowing it to melt and form glass at a lower temperature.

While soda ash is commonly used in both applications, it's important to note that there are other minerals and chemicals involved in the production of laundry detergents and glass.
