Which consequence arose historically when Islamic glassmakers added manganese?

💡 Explanation

Increased transparency occurred because manganese acted as a decolorizing agent, increasing light transmission through the glass via chemical absorption. Therefore, it allowed for clearer media for scientific instruments, rather than altering melting properties or fracture resistance.
