Perrocaliente Tempo Drop Tempo Drop Storm Glass Perrocaliente There are no noticeable scratches, but it has discolored due to aging, so I've marked it as having scratches and dirt. There are small scratches if you look closely, but they are not noticeable. Product Name: Tempo Drop Storm Glass. Other plants are not included. Size: W115xD115xH205mm (including wooden base) It was displayed in a glass case, so I rarely touched it. This is a used item, so please understand before purchasing. Product Information The Storm Glass was used by sailors in the 19th century as a weather forecaster. It is made by sealing camphor (extract of camphor tree) and ethanol in a glass tube, and it was used to observe the crystals that occur in response to changes in the climate. It is also installed in the Nautilus in Jules Verne's novel "Twenty Thousand Leagues Under the Sea." With the development of science, it has been found that there are still many mysteries about the crystallization phenomenon, and the details are still under research. Although it is difficult to use it practically as a predictor in modern times, please enjoy the changing appearance of the crystals every day with "Tempo," just like the scenery changes with the seasons. Material: Case: Borosilicate glass, beech wood Mixed liquid: Water, ethanol, natural camphor, ammonium chloride, potassium nitrate Material: Glass The wooden base harmonizes and matches any interior as shown in the photo. 【Functionality】 The Storm Glass is an item that visually indicates changes in the weather.
