Album corundum sub conditionibus caliditatis supra 2000 gradus fit.Per multiplices processus, inter quas contritio, effingens et cribrata, specie et duritia excellit tamquam materia speciali late adhibita.Album corundum non solum alte in duritie, sed etiam fragilis in textura, fortis ad secandum virtutem.Bene etiam facit in velit, se acuere, resistentia et conductivity scelerisque.Interea acido alcali corrosioni resistitur et caliditas.Ergo album corundum, sicut super duram materiam, habet excellentissimas proprietates.
