The deep blue crushed glass used in laundry is typically referred to as "laundry bluing." It is added to white laundry to help maintain or enhance whiteness by counteracting yellowing or dinginess caused by mineral deposits or detergents. Laundry bluing works by reflecting light, making clothes appear brighter and whiter.
Quartz is a colorless mineral found in igneous rocks that is commonly used in glass making. It is valued for its hardness and resistance to chemical weathering, making it an ideal ingredient for a variety of glass products.

Sodium carbonate, also known as soda ash, is commonly used in laundry detergents as a water softener and pH balancer. Silica, in the form of sand or quartz, is used in glass production to give strength and clarity to the material.

I would think that the answer is simple and resides in the simple business economic laws of supply and demand. The supply of glass for recycling is abundant whereby the material for making mineral glass countertops must be brought in and processed before making it into a countertop.
The two main constituents of glass are : Silicon Dioxide , Sodium Carbonate. Alumina or borosilicate are added depending on the nature of the glass required. Glass is a 'supercooled' liquid. , that is a liquid below its natural freezing point. Supercooled liquids do not have a crystalline structure, which pure solids have. However, glass if left for long periods of time (hundreds of years) may start to 'cloud', this is the crystals forming from the supercooled liquid.
Volcanic glass is not a mineral. It's composition is complex, and their is no crystalline structure.
Gemstones are a mineral.
Glass doesn't have a crystalline structure, or a specific chemical composition, so it is not a mineral. Obsidian is not a mineral for the same reason.
Quartz will scratch glass but not pyrite. Pyrite has a Mohs hardness of around 6 to 6.5, while quartz has a hardness of 7, making it capable of scratching glass but not pyrite.
