Flash In consumer fireworks

I recently took apart a 1-7/8" consumer aerial shell and inside, the burst charge was plain rice hulls and what appeared to be flash powder. Is that possible. Do consumer fireworks contain flash powder ever? I lit a tiny pile and it definitely seemed like flash to me.

Flash is generally regarded as a report composition, and compositions intended to create an audible effect are limited to 50mg for ground effects and 120 mg for aerial effects. In recent years, the Chinese have begun using metallic break charges (not necessarily flash) to create louder, more powerful breaks than you could achieve with plain BP or MCRH. The flash that you see in consumer fireworks is generally of a lower quality than you would make at home. If the shell you disassembled was one of the hard breaking canister shells on the market, odds are the break charge was perchlorate based.
