The Sand Hourglass was used on ships as early as the 11th century as a way of measuring time and speed at sea. The Sand Hourglass was one of the first reusable, dependable and reasonably accurate methods of measuring time. In the 16th century, the Sand Hourglass was used in churches to measure sermon lengths and in factories to calculate time for manufacturing procedures. Later the Wood Hourglass was used within the culinary industry to measure baking and cooking times. The Hourglass Home Decor is an enduring and beautiful work of art that will provide a silent, accurate, and unobtrusive channel of time. So what are you still waiting for?
