| Sand Additives | chemicals which are added to mould and core sand to overcome impurities and differences in physical properties, e.g. to minimise problems where molten metal penetrates between round sand grams |

| Secondary Steel Making | the refining (adjustment of chemical composition) which is carried out to the steel in the ladle after it leaves the melting furnace and before it is transferred to the tundish |
