Are they, the Arc Reactor and Tesseract, made of the same material?

(I haven't found any concrete theories about this).

    Any particular reason why you think they are?

    @joshbirk - I'm willing to bet it's because they're both bright blue when turned on.

My understanding is that the active component of the Arc Reactors seen in Iron Man (e.g. ignoring the casing made of steel and glass and the electrical components within) is Palladium and latterly Vibranium.

By comparison, the "infinity stone" (AKA the Tesseract) is one of a set of Gems (or Crystals) comprising the remains of an entity known as 'Nemesis'. While the actual element of the crystals are not described in-canon, I think we can be pretty sure that it's neither Palladium nor Vibranium since both are opaque metals in their crystalline forms.

What may be causing the confusion is that both artifacts seem to create the same sort of blue energy that seems common in recent Marvel features.
