Antimony oxide contents in excess of about 80% lead to the formation of undesirable grey colored fumes and thus should be avoided. On the other hand, antimony oxide contents below about 40% should be avoided because of yellowing and low fuming rates. At such increased antimony trioxide concentrations, the slag readily fumes off antimony trioxide.
