Look, if you want to keep all your fingers attached, always use a plastic stick when mixing ANY kind of pyrotechnic mixture—never wood, and definitely never metal. Safety first, right? It’s not rocket science.
And obviously, it’s much smarter to mix everything by hand while it's still in powder form rather than trying to heat it up somehow. You never know when the whole thing might just decide to react all at once. That’s why it’s better to compress a powder mixture under a press, but since those aren't exactly cheap, you can bind it with a resin—like a wood finishing varnish or something similar. Just dissolve about 500g of varnish into 1L of denatured alcohol (adjust the amount if you need to) and stir until it’s completely dissolved. Let it sit for 24 hours, and then it's ready to go.
The term calming agent—basically something to slow down the detonation speed—pretty much explains itself. For a calming agent, we use diatomaceous earth (silica), which you can find labeled as "kieselguhr." It’s used in winemaking, has massive absorption powers, and is used for filtering water or drinks, or even protecting livestock from various parasites.

It’s totally safe for humans!
Though, honestly, you could just use sawdust instead.
If you need to extinguish flames in a smoke mixture, you can actually just use regular face powder!

Just a heads up: the dyes for smoke mixtures (specifically Auramine Yellow and Rhodamine) are incredibly messy and will stain absolutely everything they touch. You seriously need rubber gloves when handling them. And for heaven's sake, do this outside, because the stains are a nightmare to wash off. I once spilled some Rhodamine powder from a tiny plastic coffee spoon and it stained my entire bathroom sink.🙂
Use your head!
