- 1 - Abstract: A filler material for filling an outlet aperture of a casting ladle or similar vessel, comprises a particulate material, each particle thereof having a core principally composed of quartz and a coating layer which covers the surface of the core, the coating layer being in the form of fine particles principally made of at least one material selected from materials of the feldspar group. This material readily departs from the outlet aperture of a casting ladle or similar vessel when the aperture is opened, thereby permitting substantially complete opening of the aperture.
