Why are manganese compounds used to make panels for stained glass windows?

Manganese compounds are used to make panels for stained glass Windows because they can create a range of vibrant colors when added to glass formulations. Manganese can produce colors such as purple, pink, and brown, which are commonly seen in stained glass Windows. Additionally, manganese helps improve the durability and workability of the glass, making it easier to shape and manipulate during the stained glass window-making process.
