This hourglass is held in place within a decorative case featuring artistically turned wooden spindles. The sand flows within an individually handcrafted mouth-blown glass chamber and is accurate to within 60 seconds per hour which is quite remarkable for a 14th century technology. No batteries required!
The glass chamber is made of sturdy 1.5mm glass with a reinforced center funnel. The sand is screened to remove particles too large and too small, then baked completely dry to eliminate any chance for condensation to form. The sand is measured into the glass in a controlled environment, baked a second time, and capped. Case ends and spindles are cut, turned, sanded and finished with a high build lacquer to protect the wood. Open cell foam shock absorbers are inserted into each case end to hold and cushion the glass.
Hourglasses were originally used on ships as early as the 11th century as a way of measuring time and speed at sea. They were one of the first reusable, dependable and reasonably accurate methods of measuring time. In the 16th century, hourglasses were used in churches to measure sermon lengths and in factories to calculate time for manufacturing procedures. They were later used within the culinary industry to measure baking and cooking times.
The hourglass is an enduring and beautiful work of art that will provide a silent, accurate, and unobtrusive channel of time. Watching the thin strands of sand create much the same effect as watching the flames of a warm fire.
Our beautifully proportioned hourglass will add a soothing, meditative focal point to any office, school, or home setting. This is an ideal gift for teachers, professionals, or yourself!
