Push or pull me, I always return the same. Boil meat for too long, It becomes like me.

Bacteria hates to see me coming, When I create bubbles, white and foaming. They'll disperse and go away to mope, What am I? I am simply ....

I sound like the very last thing you’ll do on Earth - or a deciding game piece However, my spelling specifies my use for creating rich color in many industries

Smooth, buttery and precious, Gifted to adorn, Or adorning a gift. You sleep soundly in my arms

Conical and has the flow. College parties make a spectacle of me.
