Cracked open a liquid metal thermometer that I got for a few pounds in a pharmacy, after freezing it in the fridge. Currently removing the metal from it.
Not Hg, Hg thermometers are banned now, in pharmacies at least. I do have one, but I am NOT snapping THAT open to reclaim a little Hg. No twunting way! that thermometer is my lab thermometer, with an extended and very wide temperature range. I prefer mercury thermometers for lab use by a long shot.
The medical one is useless to me completely, even before I snapped it open and started squeezing the metal out of the broken glass shards.
It contains a gallium-indium alloy, similar to galinstan. (Ga/In/Sn), so I need a little lead-free solder, and possibly a little smidgeon of copper chloride, Uncertain whether I'll need that but if I do then there's not a problem, I have some in my lab, because I made some a while back, from a load of verdigris scraped off copper metal (copper carbonate and/or acetate go under that name, its the green covering one sees on old copper rooftops) and then adding hydrochloric acid and heating until dry, some was heated some not, some just left to dry in a dessicator. And it is a lovely deep green color, like, a really, really deep clear-translucent dark dark green, kind of like the color of some seaweeds, kelp perhaps when not washed up on the beach but rather, is still wet and in the depths, growing. The seaweed that is. Although the copper chloride has grown into quite nice looking crystals due to the slow evaporation, that take the form of a randomly ordered, interconnected webwork/randomized cages formed by crisscrossing fine needle-like acicular crystals.
