History of the Sand Clock
Originating in ancient Egypt around 1500 BCE, the sand clock, also known as an hourglass, was initially used for measuring short periods of time.

Over the centuries, the sand clock has evolved, with various shapes, sizes, and materials being used to create this timeless piece of art.
Design and Construction
The design of a sand clock is quite simple yet ingeniously effective.

-
Choosing the right materials: The bulbs are typically made of glass, but other materials like ceramic or metal have also been used.
