I am currently messing around with gallium compromising aluminum. I am using a titalium lock which is just a brand of aluminum padlock and I put a gallium-indium euctic alloy on the surface of it. It’s been around 10 minutes and on the surface of the liquid is a gold colored substance. What is this? Any idea why it’s happening??enter image description here

  • $\begingroup$ By the way this happens every time i expose aluminum to the gallium-indium alloy but doesn’t happen when it’s just gallium $\endgroup$ – killakrab Jul 1 '18 at 17:08
  • $\begingroup$ It also does not react with water when I put it in water. $\endgroup$ – killakrab Jul 3 '18 at 20:00
  • $\begingroup$ If anyone else has done experiments with gallium and aluminum please leave feedback on what you think this is $\endgroup$ – killakrab Jul 6 '18 at 17:57
