Creating Ceremonial Trinkets

(I'm not sure whether to post here or in the "Heroic Companion" sub-forum.)

How much time is required to create trinkets (particularly disposable trinkets)? Is it just the time to assemble the components and cast the ceremony? This is *way* faster than a standard ACKS mage making a scroll, but the alternative "1 week per spell level" seems way too punitive.

Also - I remember asking this question in passing as part of my campaign post in the "Actual Play" sub-forum, but now the post is missing. I *know* it was there because Alex responded. Am I blind and can't find it, or is the forum sometime "eating" posts?
