More than two glass bulbs
The collection described contains a wide range of hourglass shapes. When booking, ask which examples can be viewed and what they were used for. A timekeeping instrument for a specific task can have different requirements than an object collected mainly for its own sake.
From sand to alarm clock
Kitchen timers, stopwatches and other measuring instruments are also mentioned. That lets you compare how a device indicates a length of time. Does it do so through movement, a hand, or a signal? The difference lies in both form and use.
The motif beyond the clock
Photographs, stamps and other small collectors’ items likewise carry the image of the hourglass. In this way, time is not only measured but also depicted. Note the distinction between a working instrument and a symbol on paper.
