requirements for a good slag

Slag Aggregate - an overview | ScienceDirect Topics

From visual examination, 50 particles of good, hard nickel slag are selected for each size fraction. These particles are then placed on a piece of filter paper on racks and suspended in a standard pressure cooker containing a couple of liters of water. The pressure cooker is sealed and then the water is heated to boiling at 1 atmosphere pressure.
