Free from dross; completely pure or without impurities or waste matter.
From dross (noun) + -less (suffix meaning without). The construction is straightforward: dross + less = without dross.
The term 'drossless' is poetic—in real metalworking, achieving completely drossless metal was nearly impossible, so the word became almost philosophical, representing an ideal of perfect purity.
