Alchemy is medieval chemistry. It is a part of science. And if you don't make potions or elixirs, then you are not an alchemist.
EDIT:I just hate when people sign up for things that they don't even know what it is. Now I have to run to goddamned Mahtan and then back to Drua if Mahtan knows nothing of Alchemy, yet claims to be one.
But also metallurgy, creating cast Iron for instance and various other alloys, (Alchemy in china also lead to the invention of black powder in the 9th century and first used in cannons in 1290) the bit in brackets was taken from wikipedia. Mostly it was used for fireworks and such though gunpowder a development of this was what lead to military uses of it (invented 1241)
Also I 'spose this means we do have access to explosive powder, though not the type which can be used to propel munitions in large qauntity. I guess bombs would be well within reach of our technology.
Gunpowder is chemistry, so is metallurgy. But weasel says that Mahtan isn't a chemist, which brings a real problem to how he can make gunpowder and so on.
Weasel said Mahtan isn't a botanical chemist. Chemistry within alchemy includes powders and metal working as I just mentioned which I think is Mahtan's specialty.
Then I need to learn from both of them. Question is then, does Mahtan know petroleum bases and toxins that aren't found botanically?
Gunpowder contains charcoal which is wood, Mahtan just doesn't know what would make a plant grow, or how to take care of one. However I don't know if petroleum has been discovered in this world yet, because that would require prehistoric life of some kind.
Also grinding up plants together isn't chemistry, that's herbalism.
Also also, sit your ass down because you don't need all this crap, you want it. and what's worse is your probably asking us for stuff that doesn't exist and we'd have to invent it for you, and that doesn't make any sense and is metagaming. That's like walking up to me and then describing a gun in primitive terms just so you can get a gun, despite the fact that you don't know my character and you should be 1000000% unaware that black powder exists, or could even exist.
also also ALSO, I'm currently in a burning building, I could die and no one would even know.
pre-emptive edit- Yeah I'm in service of the king, hence why I said you'd have to be my friend. If you want something from me, I'll give it to you when I make it on a whim, not when you commission me to. and that's pretty much limited to things that can't or shouldn't be mass produced for the army.
had to edit anyway- Mahtan does know metal poisons, he's very VERY familiar with mercury, seeing as that's how he loss his eyesight.
