Rare Materials Crafters?

I'm wondering where the Rare Materials Crafters are. Unfortunately, I can't remember where the one I'd encountered was, but I'm guessing there's a couple.

There are two I know of outside post-searing Ascalaon that make steel, parchement, etc.... those are the only ones I remember. One of them you actually go to on a quest from the Ambassador.

Only one I know for sure.. Is outside the Sardalic Sanatarium. His name is Artisian Daved and you do get a quest to go to him.

All of the material upgrade type npcs are named Artisian, It'd be nice to get a list on where they are located.

hes just north of the sanatarium

Between Bettletun and North Kryta, there is a crafter who will turn 5 plant fibers into a bolt of linen. Most rare craft items have to be salvaged with an expert salvage kit such as silk from garments.

There is also a rare materials merchant just outside Fort Ranik in Regeant Valley Post Searing.

Just go out and he is on the right handside in a tent.

I was sure I saw one in the early part of the Maguuma jungles, but I can't find him now.

There was one in the crystal desert I think between the first town and the next that sells vials of ink and such

There is also one just inside the Yaks Bend side of the Ascalon Foothills over by the res thingie. Had to find him on a quest from Yaks Bend. Not sure he stays there though

exactly ! There is a crafter and a collector. The crafter is the same as in fort ranik for bolts of linen crafting etc. If you enter Mamnoon Lagoon from The Wilds or Druid`s Overlook you take the way to the right (they are west) but fron fort ranik it`s really shorter ;-)
I need to know the other rare material crafters locations. (As I know one is in the desert but don`t rememebr where tough :-(
