GLASS ROD

 APPEARANCE

Made from a solid glass with variety of diameter

The glass rod may look similar to a thermometer,
but it does not have the numbers and lines along the side.

NOTE

Glass rods are sometimes used as stirrers in laboratory environments.
Glass rods are often used to spread liquids evenly onto something.
An example would be to coat glass surfaces with liquids to look at them under a microscope.
Glass rods rubbed with silk or fur were used in early demonstrations of electrical energy.
