Planes of Power Pottery Guide
Pottery is one of the more straight-forward Tradeskills to level in EQ. It is expensive, yes and it is time consuming but there aren't many recipes you have to jump back and forth between. Also once you get your Pottery skill up you can make Golden Idols of <insert deity here>. Some of them aren't very good, but others like the Golden Idol of Tunare are useful for later quests.
Once the Gates of Discord expansion pack goes live there's an alternative method to raising every Tradeskill in the game to 54. I believe these quests to be a waste of time, however, they teach you recipes that can't be learned anywhere else and for that reason must be done at least once to reach 350 Pottery.

Pottery 1 - 21
Speak with your trainer.
(Direct Route) 
Unfired Small Bowl 21 - 102
Bowl Sketch
Small Block of Clay
Water Flask
(Direct Route) Unfired Medium Bowl 102 - 122
(Direct Route) Unfired Casserole Dish 122 - 199
Ceramic Lining
(Alternative Route) 
Unfired Opal Encrusted Stein 199 - 222
If you decide to go this alternative route then you will want to make the Unfired Opal Encrusted Steins into Opal Encrusted Steins to sell for maximum profit. It is a fairly simple combine which I will explain how to do when I finish making this Pottery Guide.
Note: This recipe will be unavailable on the P99 emulator since Celestial Essence wasn't released until the Luclin expansion pack.
Celestial Essence
Lacquered Opal
Sculpting Tools
(Direct Route) 
Unfired Red Ceramic Band 199 - 242
Note: This recipe will be unavailable on the P99 emulator since Celestial Essence wasn't released until the Luclin expansion pack.
Lacquered Fire Opal
Vial of Cloudy Mana
(Direct Route) Unfired Star Ruby Encrusted Stein 200 - 335
This is probably the best route you can follow to max out your Pottery at this point. It will be much cheaper than the Idols and you can sell the Star Ruby Encrusted Steins to boxers or to players just looking to stack resistances. Truthfully, I have seen them sell better than the Idols on some serves (Ragefire, Lockjaw) whether it be the boxers or the Mitigation of the Mighty - that's just my experience.

Additional Information
- If you choose to use a Draught of the Craftsman you'll have enough juice to max out two Tradeskills usually. So come prepared with a lot of materials before popping a pot!
- If you don't see any materials that you need listed in The Bazaar setup a Buyer on a day when you don't plan on playing much to buy the items you need. Mention in general chat what you're buying (and even pay double what the other barters ask to get peoples attention if you want). Maybe someone who is killing in the zones and reading general will offload their loot to you.
- Aside from the uses mentioned above it's useful for every player to max out all of their Tradeskills for tangible useful benefits. You can only acquire things like Artisan's Prize and Sacred Prayer Shawl of the Duke from maxing out your Tradeskills. Those of you whom are wondering if this is all even worth it, well now you know.
- Under "General" in the AA window get the Salvage AA as soon as you possibly can, preferably before you start raising all of your Tradeskills. It'll save you a lot of plat.
- Every Tradeskill gets an item called a Tradeskill Trophy introduced in the Prophecy of Ro expansion pack. If you'd like to learn more about them prior their introduction then follow the link provided. Here is a list of all 6 quests for the 
Pottery Trophy.
