If pure gold is required, additional refining steps are necessary to separate out the gold. While this procedure can be used on the very small scale (roughly up to 10 grams) such as in fire assay, its use on a small to medium scale (roughly 100 grams to 10 kg) is not recommended because it emits copious quantities of toxic lead oxide fumes.
