Toy gun caps, specifically the red circles used in cap guns, contain a small amount of gunpowder, which is not shock sensitive and requires heat to ignite. Historically, these caps were made with mercury compounds, raising health concerns. The discussion highlights that modern caps may utilize potassium chlorate (KClO3) or potassium perchlorate (KClO4) as components, which can produce a noticeable smell when ignited. The safety of these materials has led to speculation about their regulation and potential replacement with safer alternatives.

I think that he was talking about those paper "blasting caps" used in some toys. There is too little explosive in those "blasting caps" for use in pistols or rifles. However, they do make a lot of noise. One can smell the burning material after a few of them go off. Some type of must be combustion is going on.syhprum said:These explosive percussion caps were not originally intended as toys but for use in pistols and rifles, when I was a boy you had to be over 16 to purchase them, I believe they are a mercury compound .
