A “round robin” project has been carried out to determine the accuracy and reliability of various models used to estimate the viscosities of industrial slags. The 21 participants were divided into measurement suppliers and modelling participants. Reference materials were issued to the measurement suppliers to check the validity of the viscosity data supplied. A data base of viscosity‐temperature‐composition data was established for 8 different categories of slags. Chemical compositions were issued to the different modelling participants and the predicted viscosities were compared with calculated values. For mould fluxes, the global % errors associated with the various models were: modified Iida (25), Riboud (30), Gupta (35), NPL (37). For non‐fluoride slag systems, the Ling Zhang, KTH and modified Iida models all performed well.
