I think flash powder has stuff other than saltpeter, sulfur, and charcoal in it. Powdered aluminum or magnesium for example and oxidizers other than potassium nitrate, namely chlorates and perchlorates.
There are a lot of pyrotechnic mixtures out there and some of them are truly bomb material.

Flash powder = Potassium perchlorate and aluminum powder.

Black blasting powder is used in granite blasting. i own blasting powder in several granulations, including one with grains about 3/8" in diameter.
