Chaya Sangyo Co., Ltd. Interior Goods Unit Storm Glass ✩* This is a "Storm Glass" (weather gauge) that was used in Europe in the early 19th century as a weather forecasting tool during voyages. It is said that the appearance of the crystals inside the liquid changes depending on the weather and temperature, and you can enjoy the unique changes in the crystals (*^o^*) The Storm Glass is made by dissolving multiple chemicals in alcohol and filling a glass container. It is also known as "FitzRoy's Weather Gauge" because Admiral Robert FitzRoy of the British Navy studied this device in detail ❁⃘*.゜ The relationship between weather conditions and crystallization inside the liquid has not been scientifically clarified, and it cannot be used to accurately predict the weather. However, the liquid and crystals change uniquely depending on changes in the surrounding weather environment, so please enjoy it as an ornamental interior (˶ˊᵕˋ˵) I think it is in a generally clean condition with no noticeable stains or scratches, but please refrain from purchasing if you are sensitive to this as it has been stored at home (>_<) It will be shipped via Yu-Yu Mercari or Rakuraku Mercari. ✦.* As it is a fragile item, I will carefully wrap it in bubble wrap and pack it m(_ _)m ＊2
