What is coal slag?
What is coal slag? Coal slag, also known as boiler slag, is a recycled product produced by coal-burning plants. When coal is "fired" at over 2,500 degrees, it melts and produces a by-product called slag. The slag is cooled through a process called vitrification which causes it to solidify and form sharp, angular granules in a variety of sizes.
