I love collecting teapots.  I bought one online and i want to collect an entire house full.  What can you tell me about teapot collecting?
Ah, yes, teapots! Some teapots today actually have a strainer built in to the spout! Super useful!
Cool. I can use that when i make tea. I will look for this feature.  Is a long spout better than a short one?
As far as the spout, that is more of a personal preference, as to how it pours easier for you, as well as it depends on if you use loose tea bags or if you use tea leafs which would need a strainer in there which ultimitely makes the spout bigger thus longer.
Now that i think about it, the teapot i bought is kind of a small one.  I would like to make tea by the gallon.  Should i look for a bigger teapot, or will i get better results  with the little one?
I would go with a larger one! They were actually derived from the bigger ceramic kettles and wine pots that could also be made from metals too. 
OK. would i get a better deal on Ebay, at an auction house, or someplace like Walmart or Amazon?  I am looking for collector teapots, not common ones.
In that case, for a collector, you would find the most unique ones on Ebay! Just be very careful that what you are buying is authentic!
I suppose i could message the seller and ask questions.  Are there any other tips you can give me?  I am afraid i have forgotten to ask you something important about teapot collecting.
I do have another tip, if you are looking for the teapot to be functional as well, you want to be sure it has a tiny air hold in the lid, this actually stops the spout from dripping and splashing when the tea is poured!
