According to online resources (which I have not researched thoroughly)...
You start by nitrating resorcinol, a medical antiseptic (I have no idea where you buy it) with a mixture of nitric and sulfuric acids. This produces a trinitro phenol compound. It is then reacted with weakly basic lead oxide to form the corresponding lead styphnate salt, which forms into crystals.
But be careful. Lead styphnate can form into two different crystalline forms: a six-sided monohydrate and a small rectangular form. The latter, when formed too long and narrow, is highly susceptable to detonation by weak static electricity from the human body. Touch her and she blows. If you don't know how to reliably form it into the more stable hex crystal, you probably shouldn't even try it at all.
By the way, lead styphnate is highly toxic. As long as it is held in a copper cup in tiny quantities, it poses no threat. But exposure to larger quantities constitutes immediate hazard to humans.
Bottom line: Either you blow yourself up by simple static, or you poison yourself through exposure. You choose.
Maybe flintlock doesn't sound so bad after all.
