From what I have heard, you have to do a "quest" per se to learn "Qalian style" or "Thestran Style" / etc. I havent travelled outside Qalia myself to verify. My uneducated guess is that you need to not just get the city faction to get in, but the crafter faction high enough in order to learn the recipes. Such as there is Khal faction, Khal artisans, Qalian Artisans, etc etc.
