    does a steel ball float in molten gold

    Answer (1 of 3): Look, whether it is molten lava, or molten gold, liquids are liquids, and whatever has the highest density will sink, what is lowest will rise.. and possible it will mix if the can dissolve into each other! Gold is hella dense! I would expect it to sink relative to lower density

    Feb 23, 2017 In addition, molten aluminum is 15% less dense than solid aluminum. Even with today’s technologies, it is difficult to compress a puck/briquette to a density greater than 85%, so this material will still float on a molten bath. Consequently, charging into a molten bath would not prevent flame impingement, resulting in melt loss issues
