Black Magic® coal slag is a recycled byproduct of lignite coalfired power plants. Our slag is created from a hotter source which creates a harder material and conforms to environmental standards. The extensive screening process we use to size our slag results in more consistently sized particles that are less likely to clog equipment.
The bituminous coal is a constituent of 'molding sand', which is also known as 'foundry sand'. Foundry sand is primarily used in making molds for metal casting.
