Avantageusement, lesdites alvéoles sont composées de carrés ou de rectangles debout sur une de leurs pointes Avantageusement dans ce cas, la lingotière a son bord inférieur dentelé de manière à pouvoir s'encastrer dans la dentelure constituée par la partie supérieure dudit dispositif à grilles.  Advantageously, said cells are composed of squares or rectangles standing on one of their spikes. Advantageously, in this case, the mold has its serrated lower edge so as to fit into the serration constituted by the upper part of said grid device.

L'invention sera mieux comprise à l'aide de la description  The invention will be better understood from the description
