They cover the basics

Usage examples of primers.

After he had gained more than mere grudging attention from the gun captains, Sir Peter had them gather around closer and, with fingers that were big and work-stained and scarred, but still sure and rock-steady, he rapidly dismantled a brace of the friction primers and showed all of them the very simple works.

After examining two of the primers for a while, Fahrooq had the gun crew on duty swab and reload the waiting culverin.

Once he had probed the touchhole, he inserted one of the primers picked out at random from the box Sir Peter had brought, attached the lanyard hook, took a stance, took in the slack, then gave a sharp jerk.

Sir Peter kept the duty gun crew busy, allowing the assembled gunners and officers to personally use the entire box of primers he had brought along on not just the long eighteen-pounder but on some of the heavier pieces on the gun decks below.

I showed them off to the fucking officers, they never stopped frowning and all and turned them primers down flat.

Furthermore, thanks almost entirely to the experiments of Rupen and Peter to improve upon the cannon primers Peter had been making, we now have matches in this world and timenot very many, just yet, true, but due to the meticulous records of their experiments kept by Rupen, we now know just how to make them.

But, as I now recall, the cannon primers used the same basic compound as is used to make matchesphosphorus, sulfur, and a few other common chemicals, plus ground glass.

Also cordite, Primacord, smoke pots, gelignite, primers and Navy powder.
