[yltmirfj] Sealed box

Store a object for a long time inside a sealed container, for example a time capsule.  We especially want the container to be watertight.  How should the container be constructed?  What should it be made of?

We need a nonreactive material that is not too difficult to work with and not too valuable (or else the container itself will become a target for theft).  The old school material of choice was lead; are there modern metals or materials that are superior, e.g., aluminum or stainless steel?

How can the lid of the container be sealed to stand the test of time?
