A (non-spinning uncharged) black hole with diameter 1+5/8th inches (so it fits in the box) has a mass of about 2.3 earths.
(Near as I can tell QGP filling the whole box is around a ten billionth of that.)
Of course the box would Very quickly no longer be outside the black hole. QGP would also cause the box to no longer be a container in short order. To put it mildly.
Wait until I fill that box with quark-gluon plasma.
