Unknown Aluminum Phenomenon
I Haven’t seen this before, potentially from the high heat the aluminum was at, though I’ve got it this hot commonly without the effect. metals expand when heated/shrink when cooled this seemed to be opposite. I haven’t split a ingot to see if a potential void was caused. No outside shrinking is visible on these ingots.

Just an idea: the top layer cools, becomes denser, pressing down on the molten aluminium below, which is forced out of the top layer's weakest point, probably somewhere in the middle.
Once or twice I have seen ice cubes fo this in the freezer. The cube will have a spike sticking straight up. Very strange, defies gravity.
Aww so sweet! He made aluminum cupcakes.🧁😂🤨
Very nice. I never had ingots do that before. I wonder what caused it? I had air bubbles form on the top, but that is usually due to moisture.

This is just aluminum from a old radiator, I’ve only twice seen this happen. I believe it’s temp related but I’m probably wrong and no moisture could possibly cause a formation like this. I believe it being so hot makes the aluminum contacting the mold cool quick causing a large temp difference compared to the inside metal compressing it out and up.

Do a video where you torch or heat up the cupcake pans first and see if it has the same results?
