Abstract:
An induction furnace for the synthesis of glasses, comprising a reactor inside which a support device for a crucible containing a mixture of constituents of a glass to be synthesized is arranged, the support device having an upper part formed with a planar element, characterized in that said planar element is associated with a pair of sleeves between which an annular element able to engage the outer wall of the crucible is inserted; and in that a first of said sleeves has such longitudinal dimensions that the crucible is supported in the annular element in such a way as to be spaced from the planar element, and the second of said sleeves has such longitudinal dimensions that its top edge is at a level higher than that of the top edge of the crucible, to obtain a homogeneous temperature region extending at least along the entire height of the crucible.
