<p>A method of characterising molten materials comprising the steps of effecting flow of the material through means 24 for filtering out inclusions within the material, monitoring the flow of the molten material through the filtering means, and comparing the measured flow with a predetermined flow characteristic to enable determination of the character of the material. The molten material may be a metal such as aluminium. The filter 24 may be in the base of a crucible 22. Monitoring may be of the flow rate or rate of change of flow of the molten material. The comparisons may be of curves of filtrate weight against filtration time (eg. figs. 8 and 13).</p> |
