What Is Slag Glass? - The Spruce Crafts

What is coal slag? This stuff is boiler slag, which is a recycled product from coal burning plants. When coal is "fired" at over 2500 degrees it melts and produces a by-product called slag. When the slag is cooled through a process called vitrification, it crystallizes, forming sharp, angular granules in a variety of sizes.

The Health Risk of SLAG – an Industrial Waste Product ...

The open-hearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface. Impurities, including carbon, are oxidized and float out of the iron into the slag.
