Pricing and DCs for alchemical items

[Napftor]

Is there a formula I'm missing for either the pricing or DCs of alchemical items? After an hour or so of tinkering, I've come up with a pretty good DC calculation system (except for the damned tindertwigs) but am at a loss for how these items got priced the way they did. Can anyone throw me a bone here?

I don't think there is one, I think they are just made up

Yeah, that's what I was afraid of, but was hoping some enterprising freelancer had done the work ahead of me. Have to make sure to put my calculation rules into the book then.

I remeber looking at DCs for items that appeared in dragon and other books and trying to do somethign like this, but there was no forumal to be found.
