A method for representing slag in a molten metal stream is disclosed, comprising the steps of obtaining and storing digital images of the molten metal stream, identifying areas of similarity on the basis of texture and intensity, defining a subset of those areas, comparing at least one selected property of the subset against a defined parameter and generating an output signal on the basis of the comparison, wherein the output signal is indicative of the presence or absence of slag. Also disclosed is a system for carrying out the above method and visually displaying the resulting output signals to facilitate operator analysis of the results. The system allows use of inexpensive optical equipment in place of an expensive infrared detection apparatus.
