Seems like a daft question but does anyone know what the red substance is in a thermometer?

Alcohol I believe on accout of it not being as toxic as mercury if it escapes, but not freezing at such a high temperature as water.

Thanks for that. I suspected it probably was alcohol, but no-one would believe me. Other people think it could be "mineral spirits having a strong petroleum odour, eg Petroleum Hyrdocarbon, mixed with a red coloured dye." I still go with the alcohol theory.

Although the ones I have seen have been alcohol, it does appear that other spirits are used - presumably as long as they have a wide enough range between melting and boiling points it doesn't really matter.
Google is your friend. See http://www.newton.dep.an...kasci/gen01/gen01583.htm

Always been alcohol as far back as I can remember, but not enough to get you tipsy.
