17. Bizarre Fact about my Compound Galena

# data[].attributes.body
A bizarre fact about my compound galena is that during the times of Ancient Egypt, galena was applied around the eyes to reduce the intensity of the glare of the sun and used as a method to repel flies from it. This factor was good for the Egyptians as this was a potential leading cause for diseases.

When a liquid is heated, it eventually reaches a temperature at which the vapor pressure is large enough that bubbles form inside the body of the liquid. This temperature is called the boiling point. Once the liquid starts to boil, the temperature remains constant until all of the liquid has been converted to a gas. My compound galena’s boiling point is 1.150 grade Celsius.
