Cerrosafe melts around 160……….I use it for making chamber casts.

Gallium.

That's what I was thinking. I believe it is used in sprinkler systems for fire protection.

Gallium sounds interesting.
I think it melting point is a little to low.
It will melt in you hand.
"Elemental gallium is a liquid at temperatures greater than 29.76 °C (85.57 °F), and will melt in a person's hands at normal human body temperature of 37.0 °C (98.6 °F)."
