The invention relates to a method of manufacturing successive spherical glass articles, in each of which is accommodated a three-dimensional object of figuring, which method comprises the following steps, to be performed in a suitable sequence, of: (a) providing a container with a mass of molten glass, which container comprises a discharge opening through which liquid glass can be delivered; (b) providing thermally resistant figurines; (c) wholly enclosing successively at least one figurine by molten glass by feeding molten glass thereto from at least two sides; (d) portioning the molten glass before or after step (c) such that molten glass masses are formed, in each of which a figurine is embedded; and (e) modelling these masses to a spherical form by substantially omnidirectional rolling for a time with simultaneous cooling so that the glass solidifies.

Cette invention porte sur un procédé de fabrication en série d'articles sphériques en verre renfermant chacun un objet ou figurine tridimensionnel. Ce procédé comprend des étapes à réaliser selon une séquence appropriée et consiste à: (a) former un réceptacle au moyen d'une masse de verre fondu, ce réceptacle comportant un orifice d'évacuation par lequel peut être introduit le verre liquide; (b) former des figurines résistant à la chaleur; (c) renfermer totalement et successivement au moins une figurine en faisant fondre le verre et en l'introduisant par au moins deux côtés; (d) fractionner le verre fondu avant ou après l'étape (c) de façon à former des masses de verre fondu incluant chacune une figurine; et (e) modeler ces masses pour leur donner une forme sphérique en les roulant de manière omnidirectionnelle sur une certaine durée avec refroidissement simultané de sorte que le verre se solidifie.
