how would i go about properly mixing powders? My guess would be to dissolve both powders into a liquid (what solvents would work best with alp and binder, would purified water work fine?) and then evaporating, would that work? saw people saying just throwing in a bag and shaking or blender but seems like theres no way that would properly mix down to the precision you would need.

Yeah things like a blender aren't even going to be close to homogeneous. The absolute best way to mix two powders into a homogeneous mixture is actually using a ball mill. You can rig one up by using a rock tumbler, filling it with the two powders along with ball bearings and running it for 24hrs. Of course most people aren't going to do that so the only other way you might be able to get kind of close is dissolving in a solvent like methanol and stirring on a magnetic stirrer until evaporated, then taking the result and thoroughly grinding with a mortar and pestle. I don't actually know much about what the binders are though, if it's something like chalk or a mineral then it's not going to dissolve in any normal solvent, but otherwise most things are soluble in methanol.
