1. A device for characterising at least one liquid material, comprising:
characterisation means,
rotating means for mechanically stirring a liquid melt of said at least one liquid material, the rotating means comprising:
a central part extending along a longitudinal axis and configured to be positioned above the liquid melt of said at least one liquid material, the central part comprising a wall, an inner cavity delimited by the wall and forming an analysis chamber, and a first end connected to the characterisation means, and
a plurality of mechanical stirring blades connected to a second end of the central part, opposite to the first end of the central part, the second end of the central part extending over a height along the longitudinal axis of the central part and being hollow so as to ensure fluidic communication between the inner cavity and the liquid melt of said at least one liquid material,
wherein the characterisation means is configured to enable the analysis of the surface of said at least one liquid material, situated in the portion directly in line with the inner cavity of the central part,
wherein the mechanical stirring blades are configured to be totally immersed in the liquid melt of said at least one liquid material,
wherein the central part comprises one or more orifices formed in a traversal manner in the wall and configured to be situated above the second end of the central part bearing the mechanical stirring blades when the device is in place in the liquid melt of said at least one liquid material, the orifice or orifices being configured to be partially immersed according to a height in the liquid melt of said at least one liquid material, and
wherein each mechanical stirring blade comprises at least one stirring wing oriented according to a non-zero angle of orientation with respect to a transversal axis perpendicular to the longitudinal axis of the central part.
