In 2023, after four years of decline, there was growth in the global antimony ore and concentrate market, when its value increased by 2.4% to $1.9B. In general, consumption, however, recorded a deep reduction. Over the period under review, the global market hit record highs at $4.4B in 2012; however, from 2013 to 2023, consumption failed to regain momentum.

The tinctures made during class were made with antimony fume, an impure antimony oxide that was retrieved from an industrial process. Since this may be difficult to get, students will have to processes their own raw antimony sulfide, also known as stibnite.
