Water-glass with French finished antiqued wall plaque. Hand-blown by master craftsman glass vessel with elegantly shaped spout. Fill with colored water to approximately one inch above where the spout joins the glass body. Then suspend weather glass from hanger.
Early science…working on air pressure and filled with colored water this weather-glass accurately predicts rain and storm.
King George III collected scientific instruments. Not for function, but for form and beauty. The brass arch, lightly distressed French finish wall plaque, and brass details turn this weather-glass into a work of art.
It was a bit awkward up to the moment our lovely guest wanted to know what exactly was the liquid in the weather-glass. Serving a chilled Pinot Gris, we joked that it only worked with a genuine Vinter’s Reserve. Admittedly a roundabout way to start a conversation on the weather. But the ice was broken, so to speak, an our guests toasted to a most ingenious invention.
The Weather Rises and Falls
Weather forecasting is just like it was some three centuries ago. Called the “poor man’s” barometer, this decorative hand blown glass instrument accurately forecasts weather hours in advance, just by using atmospheric pressure. By the 17th century, square-riggers carried a weather-glass next to the compass on the chart room table. The weather-glass invokes the spirit of times past when people used simple inventions to guide their daily lives, often with highly satisfying results.
Weather-Glass Installation: The weather-glass should not be hung in the sun or near a radiator, as excessive heat prevents proper operation. Once hung in place, do not move it unless necessary. A small piece of blotting paper can be placed in the drop catcher to absorb the drip from the spout in stormy weather.
How to fill the weather-glass: Hold spout under tap and fill with a thin stream of water. Water level of the bottle itself should be approximately one inch (2.5cm) above the place where the spout joins the bottle. If used outdoors, fill with rubbing alcohol during winter, to avoid freezing. Use a drop of food coloring to achieve the desired color.
Consult the weather-glass every day. The weather-glass accurately forecasts weather changes 8 to 12 hours in advance. The rise and fall of the water level in the curved spout indicates weather conditions as follows:
Slow rise to top of spout: Indicates approaching storm 8-24 hours in advance. The storm may or may not change its course.
Rapid rise to top of spout: Indicates approaching local storm. If the storm changes its course, this will be forecast by immediate fall of the water to normal level.
Bubbling out of spout: Indicates rapidly approaching local storm only a few hours away. Rapid fall below top of spout during storm: Indicates that the storm is nearly over.
Holding steady halfway up spout: Indicates clear weather.
Note: Hot weather will make water level rise about 1″ (2.5cm). Disregard this as “forecast”, as it is caused by a sudden increase in temperature.
