Refractories make the world go round. The modern world cannot function without refractories, yet so many people are unaware of their importance. Refractories are responsible for the bricks found in your family backyard fire pit, the steel soaring up into the sky on a bridge, and the many of the materials in the car you drive. Minerals make refractories possible. Refractory and Abrasive minerals define Great Lakes Minerals, LLC!
