Glass float thermometer dome

The physicist Galileo Galilei discovered that the specific gravity of the liquid changes with temperature.
This thermometer is made using that principle.
A glass sphere that rises and falls according to the temperature indicates the temperature.
The actual temperature is read by the plate attached to the bottom glass sphere of the glass sphere floating in the upper layer.
An interior thermometer with a modern dome-shaped body and natural wood base.
