{"product_id":"fitzroy-storm-glass-weather-predictor","title":"Fitzroy Storm Glass Weather Predictor","description":"\u003cp\u003eA sealed glass vessel of clear liquid, mounted on a small wooden base, in which crystals form, dissolve and drift as conditions around it change. The design goes back to nineteenth-century ships, where Admiral Robert FitzRoy popularised it as a barometer of sorts. Whether it forecasts anything reliably is a question people have argued about for two centuries; what is beyond argument is that it is quietly fascinating to have on a desk.\u003c\/p\u003e\u003cp\u003eThe readings are traditional and easy to learn. Clear liquid was taken to mean fair weather ahead. Small clouded crystals suggested rain. Crystals climbing or floating high in the vessel meant a storm was on the way, and feathery, scattered formations were read as snow or frost. In practice the glass responds mainly to temperature, so it changes most visibly when a room warms up or cools down across a day.\u003c\/p\u003e\u003cp\u003eThree sizes are available, from a small desk piece to a larger shelf ornament. The base is solid wood and the vessel is sealed glass. Keep it out of direct sunlight and away from radiators, both of which will drive the crystals to one extreme and hold them there. This is a decorative object, not a scientific instrument or a substitute for a forecast. Keep it out of reach of children and pets, and do not attempt to open the sealed glass.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSizes: S 12 x 6cm, M 18 x 8cm, L 22 x 10cm\u003c\/li\u003e\n\u003cli\u003eSealed glass vessel on a solid wood base\u003c\/li\u003e\n\u003cli\u003eCrystals shift with ambient temperature and conditions\u003c\/li\u003e\n\u003cli\u003eDecorative object - not a scientific instrument\u003c\/li\u003e\n\u003cli\u003eKeep out of direct sunlight and away from radiators\u003c\/li\u003e\n\u003cli\u003eDo not open the sealed vessel\u003c\/li\u003e\n\u003cli\u003eKeep out of reach of children and pets\u003c\/li\u003e\n\u003cli\u003eDust the glass with a dry cloth\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lockhone","offers":[{"title":"Small 12 x 6cm","offer_id":58858436952448,"sku":"LH-BWL-0152","price":69.99,"currency_code":"GBP","in_stock":true},{"title":"Medium 18 x 8cm","offer_id":58858436985216,"sku":"LH-BWL-0152-2","price":69.99,"currency_code":"GBP","in_stock":true},{"title":"Large 22 x 10cm","offer_id":58858437017984,"sku":"LH-BWL-0152-3","price":69.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/4737\/5232\/files\/Storm-Glass-Science-Decor-1682461610.jpg?v=1788503406","url":"https:\/\/lockhone.com\/products\/fitzroy-storm-glass-weather-predictor","provider":"Lockhone","version":"1.0","type":"link"}
