Mo-Sci is a world leader in high quality precision glass technology working with many fortune 500 companies as their priority or sole provider of specialty glasses. Mo-Sci’s glass microspheres, fibers and frit have many uses including (internationally recognized) healthcare applications. Engineers at Mo-Sci are recognized world-wide for revolutionary research, development, and manufacturing of glass for specialty applications. Companies seek out Mo-Sci with seemingly improbable ideas to research and develop into an application that the company then takes to market.

Mo-Sci is headquartered in Rolla, Missouri (USA), home to Missouri University of Science and Technology (Missouri S&T), where the idea of Mo-Sci originated in 1985 with company founder, Dr. Delbert Day, Curators Professor Emeritus in Materials Science and Engineering, at Missouri S&T. Mo‑Sci was acquired in 2021 and is now part of the Heraeus Group, a broadly diversified family-owned technology company. Learn more about Heraeus Group at
