    Among alkaline oxides, iron oxide and manganese oxide are better flux agents than magnesium oxide. Furthermore, slags with a high magnesium content are less viscous than slags containing calcium. In the production of mineral wool, surface tension also plays an important role in successful defibration, because it is necessary that the molten substance has a free access out of the furnace and ...
