When light weight aluminum engages with any type of eruptive, it makes the nitroglycerin much more delicate. With Catalyst, that would certainly be nitrocellulose, that makes up around 20 percent of the guide compound. The light weight aluminum additionally responds with bismuth oxide (60 percent of the primer)yep, that coincides bismuth in nontoxic shot with a thickness similar to leadto develop what Federal designer Sandstrom calls a "thermite response," which is an expensive way of saying that the aluminum gets the bismuth really, actually hot.

In early black powder guns such as muzzleloaders, the primer was basically the exact same chemical as the primary propellant (albeit typically in a finer-powdered kind), yet put into an outside flash pan, where it might be sparked by an ignition source such as a slow-moving match or a flintlock though some muzzleloaders have guides like cap gun caps.

As gunpowder will not shed when wet, this made it difficult (and even difficult) to fire these sorts of tools in rainy or humid problems. Modern primers, by comparison, are a lot more specialized and unique from the main propellant they are designed to ignite.
