How old is the thermometer? Is a manufacturer or brand name on it? If the thermometer is older than 35 years, finger away, could be mercury. However, there are other metallic alloys which are also liquid at room temperature, you do not see it. Normally you can see it at the melting point, which is at -38° with mercury. The other alloys are usually liquid far beyond this. But in the narrow glass tube you can’t see it right.

If the liquid is silver, then can be mercury, otherwise not.

If so, you can possibly estimate the weight, then only a much more complicated analysis helps.

What’s “very old”? For a long time, the non-toxic Galinstan has been used as a mercury substitute.

If the temperate owl shimmers silvery, it is guaranteed mercury!

Wrong. Galinstan has been used for many years.

Yeah, and you say, if it shimmers silvery, it’s mercury. Galinstan also shimmers silvery, you genius.
