Wrong the tesseract was used for that in the avengers and as an infitinty stone cannot be extinguished. It became super  heated from teleporting red skull that it just melted through the floor and the cube was cooled. As stated in avengers 2 the cube is just a containment device the actual stone is inside the cube so the containment box, the "cube" became so hot it melted through the metal floor and once in the ocean cooled down to normal where it was taken by howard stark and kept at SHIELD. Which they later used it to try and create their own weapons but then Thor used it to go back to Asgard and Heimdell used it to jumpstart the bifrost as it was the only thing they had powerful besides odin that could jumpstart the generators of the bifrost they were rebuilding during the avengers.
