A new model of saline icicle growth has been developed. It predicts that saline icicles should be shorter and broader than their freshwater cousins and that the length growth of saline icicles eventually stops when the tip temperature reaches the ambient temperature, rather than when the water supply to the tip ceases as for pure icicles. Both of these predictions are borne out by a series of cold#x2010;room experiments in which saline icicles were grown under controlled ambient conditions. When the model predictions are compared with the experimental results, the model is found to behave not too badly considering the assumptions of the model and the limitations of the experiments. Final predicted icicle masses are generally too high, but within 7 to 32 of the observed masses.
