The consist of two glass bulbs that are connected with each other by a small neck in the middle. These bulbs contain sand that can flow from the one bulb to another. By turning the hourglass over, sand enters from second top bulb into first bottom.

The ancient Greeks first used sand timers in the 3rd century BC. These early hourglasses were filled with oil that would slowly trickle out, much like pouring water from a bottle today for slow cooking wine or vinegar reduction sauces! These were previously used to time speeches in court or high religious functions. Hourglass sand timers later became very popular in Europe during the Middle Ages. Used for timekeeping during church services and in scientific experiments. Sailors also used these to manage time while sailing in ocean.

The history and evolution of hourglass sand timers.

After those early days, new 10 minute hourglass timers got even more precise. The marine chronometer is a highly accurate clock used in the 18th century by John Harrison. This was a huge advancement as it encouraged sailors to sailed the seas better and make their back home without any accidents. For this reason, that invention starts the decrease in use of hourglass sand timers and brings clocks and watches(instead as accurate measurements for time.)
