About Hour Glasses:
Hourglasses were the first dependable, reusable and reasonably accurate measure of time. The rate of flow of the sand is independent of the depth in the upper reservoir, and the instrument will not freeze.
From the 15th century onwards, they were being used in a wide range of applications at sea, in the church, in industry and in cookery.
