How to Clean Antimony Objects: Tips and Techniques
Before we dive into the cleaning process, it is important to understand why antimony objects tarnish in the first place. Antimony, like many other metals, can react with air and moisture, leading to the formation of a thin layer of tarnish. This tarnish can make your antimony objects appear dull and lose their luster.

How does antimony improve lead-based castings?
In lead-based alloys, antimony is added in the range of 1/2 percent to 12 percent and most commonly it is used in a range of 1/2 percent to 6 percent antimony and the balance of the alloy is lead or tin. The use of a little antimony in castings will help material flow so it acts to improve the feed into a part compared to pure lead.

Chemistry of Antimony (Z=51)
Antimony trisulfide. Antimony trisulfide, (Sb_2S_3), is a sulfide mineral commonly called stibnite or antimonite. Antimony trisulfide exists as a gray/black crystalline solid (orthorhombic crystals) and an amorphous red-orange powder. It turns black due to oxidation by air. Antimony trisulfide is the most important source for antimony.

Antimony Metallurgy
Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. Valentine of Germany.
