👉 Slaggability is a property of materials that allows them to absorb and store heat. This means that when there's heat present, the material will retain it more efficiently than if it were not absorbing it. For example, insulation in buildings can be designed with slaggability to help keep warm air from escaping, while also keeping cool air inside. In other words, slaggability is a property of materials that allows them to maintain their thermal properties better than they would without this property.
