Alternate Craftsmen Classes

[YianKutku]

What I wanted to know was: do they also create and use paper?

Off the top of my head, orchestrion rolls are made from paper.

Blank spools of paper onto which scores of sheet music can be transcribed by means of perforation.

Apart from that, there's also "Bamboo Paper", classified under "Lumber" for some reason:

Thinly sliced bamboo used to preserve the aroma of rare fragrant wood.

(I admit I only remember Bamboo Paper because I got some from a treasure map chest, and then had no idea what it was used for, and so the stack sat in my inventory for a couple of months.)

Interestingly, there is a game in Eorzea implied to be equivalent to rock-paper-scissors, called "stone-parchment-shears" (as mentioned in the description for the Fiend Worm FSH bait). Which suggests that for the majority of people, parchment is what they think of when it comes to thin, flat writing material.

From here, I wondered, if parchment/paper exists, then which craftsman trade is in charge of making it? Presumably it would be CRP for paper and LTW for parchment, guilds which happen to share a home city.

CRP makes the Blank Orchestrion Rolls. Also, the Arcanist grimoires made by ALC usually involve wood logs in their crafting recipes, which implies that the pages are made of paper. (Grimoire recipes also usually have leather, but it's implied to be for the covers.)

Parchment is a bit harder to look up. I'll let others more well-versed in lore pick that up.

For example, glass is a common material in Eorzea, and glassblowing is an entire trade all its own. Yet, none of the 8 crafter classes we have so far seem to include glassblowing as part of their scope.

ALC creates the various glass-related items, but I admit I don't know if they actually blow glass, or if it's done by some form of fantasy alchemical magic. You're right that there really should be a whole separate trade for glassblowing, or at least that Alchemists will probably be spending most of their time handling orders for glass.
