I want to take a Le Creuset pot in my cabin luggage on united airlines from San Francisco to Australia. Any chance they may consider it a dangerous object? Anyone have any experience carrying this type of item?
Since you are departing from the US, what you can bring on board is governed by the US TSA regulations. The TSA has a handy web site where you can search for various objects to learn whether or not they are allowed (see the search feature in the upper right). Searching for "pot" turns up a variety of hits including "metal pot", "cooking pot" and "pot for cooking". All of them have the answer:
You may transport this item in carry-on baggage or in checked baggage.
