Abstract: An apparatus for liquefying meltable material comprises a container adapted to be filled with the material to be liquefied. The container has a heavy bottom wall formed with closely adjacent perforations which taper in downward direction. The sum of the open cross-section of the perforations at the upper face of the bottom wall is only slightly smaller than the total area of the latter, whereas the sum of the smallest cross-sections of the perforations is only a small fraction of the total area of the bottom face of the bottom wall. The bottom wall is heated by electrical heating elements located in ribs separating the perforations from each other to a temperature to liquefy the material passing from the container into the perforations and the liquefied material flows in a collecting trough arranged below the container and separated by a heat insulating layer therefrom.
