Sandglasses and hourglasses

A sandglass measures an interval rather than telling the time of day: a fixed quantity of fine material runs from one bulb into the other through a narrow neck. Documented in Europe from the fourteenth century, sandglasses were used on board ship to time watches and to measure speed with the log line, in churches to time sermons, in schools, laboratories and kitchens.

Early glasses were made as two separate bulbs bound together at the neck with a diaphragm and wax and thread; one-piece blown glasses only became usual in the nineteenth century. The 'sand' could be powdered marble, eggshell or metal filings, carefully sieved and dried. Sets of graduated glasses in one frame allowed several intervals to be timed.
