An hourglass is a device used to measure the passage of time. According to the American Institute of New York, the sand-glass was invented in about 150 BC. An hour-glass comprises two glass bulbs connected vertically by a narrow neck that allows a regulated flow of material (historically sand) from the upper bulb to the lower one. Esington Glass has created a modern interpretation of this old instrument which represents the acme of functional design.
It is the simplest way to power up your productivity in an elegant and beautiful package. Each Esington Glass is filled with millions of solid steel Nano spheres which produce a wonderful visual effect as they bounce chaotically around the glass producing subtle, peaceful white noise.
Factors affecting the time interval measured include the steel quantity, the coarseness, the bulb size, and the neck width. Esington Glass can be reused indefinitely by inverting the bulbs once the upper bulb is empty.
The Esington glass is hand blown by highly skilled artisans. Each glass is a unique piece of art both simple and beautiful. A device that is functional and will decorate your workspace at home or in the office – a new take on time boxing. To order your own desk set visit their website.
