Which element was used in flashbulbs?

Anyone else remember having a camera that needed flash bulbs? those little cubes that you had to attach to the camera? And how frustrating it was to realize that you didn't have anymore?! As well as having to have room to carry enough of them along with you?

Sandyberry, I remember further back when cameras needed to have a bulb loaded for each shot. at least the cubes took 4 shots!

guess I'm showing my age by my first comment, Lol 😉

Sandyberry, and just how old is that?

Magnesium fire starter

Old man X, it was also used in Mercedes racing chassis & which caused a terrible disaster in the 1955 Le Mans; the car crashed into the crowd and then burst into an inferno because of the magnesium.
