Although true lime activity values are available from gas/slag sulphur partition in lime-alumina, lime-silica and, to a certain extent lime-alumina-silica melts saturated with calcium sulphide, no attempt has been made to assess true lime activity by slag/metal equilibrium studies on sulphur partition. The first aim of the present investigation was, therefore, to assess the true lime activity in calcium sulphide saturated melts making use of calcium sulphide crucibles whereby the activity of calcium sulphide Can be taken as unity simplifying the problem. Calcium sulphide Crucibles have been slip-cast successfully for this purpose using absolute ethanol, but it is unfortunate that this project met with little success owing to the poor performance of these crucibles during melts. In the second part of this work, attention was therefore focused on Fe0 and magnesia crucibles were used. Using these crucibles, the following conclusions have been reached on slag/Metal sulphur partition between lime-alumina, lime-alumina-silica or to a certain extent, lime-silica melts containing magnesia and ferrous oxide, and pure molten iron at 1550
