At Glass Rocks our products are comprised of recycled slag that has similar characteristics to ordinary glass. Slag is the byproduct of steel production. After iron ore is smelted and processed, the remaining residue is a glass-like, often glossy material that takes on different colors depending on the minerals and elements present in the iron. Though it is known by several names, slag glass is a variety of pressed glass that is universally celebrated by collectors for its characteristically subtle variations in color and opacity. Adding to the beauty of slag glass; also known as malachite glass, marble glass, and mosaic glass is its rich history that reflects the ingenuity of turn-of-the-century glassmakers.
