assaying
Checking metal purity
Assaying is the process of testing a substance to determine its composition or quality.
The term applies especially to analyzing ores or precious metals to establish their purity: assaying gold samples from the mine.
More broadly, assaying means attempting or trying something: She was assaying a difficult role for the first time.
