A well-made steel box the masssiv enough of the normal cooking temperature will withstand. You should also not be in the embers. I have the smoke chips soaked directly into the box, which I had the hot box filled with the chips and then put in a bowl of water. If too much water in the bowl is floating the chips out of course :) water After half an hour have the box simply placed in the sink so that the water can easily drain übschüssige to the non-welded. And then just to set the box on the grate over the coals and make the rest of the chip.
