A curious thermometer

[Chris GillParticipant @chrisgill22114]

A friend of mine found a rather curious thermometer in the cellar of a house he's renting and sent me a photo yesterday. My guess is that it's for brewing wine but if anyone else has theories around the combination of Fahrenheit and Weeks …

If I could be bothered digging out my books on engineering thermodynamics (anyone remember Rogers & Mayhew) I could deduce something from the aparently linear rate of cooling but, hey, it's the weekend

When time and temperature mean the same thing?

Intruiging! If that's a wooden backboard then not for immersion and the temp rang is patently ice to biological temps in degF.
it may not be a rate of cooling and more a temperature range you need to keep ambient for those periods.

Probably about 10min, Mike

…. I didn’t start thinking about it until after pgk posted

Plenty of these around in the 1950's, my Dad used them in his greenhouses and they were also used in still air incubators and I remember seeing this use in the late 60's. I believe they were just a general purpose item available in most general stores or ironmongers.

I hadn't thought of chickens but the house is part of a farm so it makes perfect sense.

Thanks MichaelG
