One of the promising technology that guarantee the high-purity of the processed metal is induction skull melting. Thequality of the melting process within such a system strongly depends on the cold crucible design. Hence, the experimentalinvestigation of the cold crucible melting was performed. The experimental investigation was performed for various initialmass of the load. The results of that analysis were used for the assessment of the alloy temperature during the process, freesurface shape and the area as well as the liquid metal emissivity. The collected results of the thermal analysis showed thatthe temperature of molten metal increased within the power input increase. Moreover, results of that analysis showed that thecharacteristic tooth-shaped jags were created mostly at the centre of the cold crucible segments. In addition, experimentalresults are suitable for the numerical models validation and further investigation of the cold crucible design.
