Meaning

A metallic tincture must be both readily fusible and incombustible, together with being fixed. These qualities are coordinated, not contradictory within the source’s account: the preparation should flow and penetrate without being dissipated by combustion. The description concerns a claimed operational performance, not a guarantee that the material is safe, nonreactive, or identifiable by one modern substance.
