Just as not all materials conduct various forms of energy equally, it stands to reason that not all elements will be able to be contained by the same substance. There's also the possibility of using magic itself to create a sort of barrier to serve as a containment chamber, but it would have to be done in such a way that it did not require continual channeling or upkeep in order to do its job— otherwise these devices won't be accessible to the general public, which then defeats the purpose.
