{"product_id":"ancien-briquet-electrochimique-luminus-a-pile-de-grenet","title":"Vintage \"Luminus\" electrochemical lighter with Grenet battery","description":"\u003cp data-start=\"77\" data-end=\"1004\"\u003eRare and spectacular electrochemical table lighter by Luminus, using an ingenious electrical ignition system with a Grenet cell. This type of scientific lighter worked through an electrochemical reaction: the large main reservoir contained an electrolytic solution of potassium dichromate into which a carbon electrode was immersed, while the vertical piston allowed a zinc electrode to be lowered to temporarily activate the cell. The current produced then heated a platinum filament located near the wick of the small side reservoir containing the combustible alcohol, causing ignition. A true concentration of Belle Époque technology, this lighter combines cobalt glassware, precision mechanics, and electrical experimentation in an object that is particularly sought after today by collectors of tobacciana and antique scientific instruments. This is the large format version, standing nearly 22 cm high.\u003c\/p\u003e\n\u003cp data-start=\"1006\" data-end=\"1354\"\u003e✦ Provenance: France - Luminus brand\u003cbr data-start=\"1044\" data-end=\"1047\"\u003e✦ Estimated period: Circa 1900-1915\u003cbr data-start=\"1081\" data-end=\"1084\"\u003e✦ Dimensions: approx. 22 x 10 x 8.5 cm\u003cbr data-start=\"1120\" data-end=\"1123\"\u003e✦ Material: Cobalt blue glass, nickel-plated metal, and textile\u003cbr data-start=\"1178\" data-end=\"1181\"\u003e✦ Condition: Good overall condition with signs of use and slight oxidation, mobile mechanism, assembly appears complete with original wick preserved.\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-start=\"1356\" data-end=\"1535\"\u003eAn emblematic piece of Belle Époque domestic experimentation, ideal for a collection of rare lighters, scientific objects, or antique technical curiosities.\u003c\/p\u003e","brand":"Brocante Jolbro","offers":[{"title":"Default Title","offer_id":53873130930509,"sku":null,"price":329.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1049\/5053\/files\/20260510_113608.jpg?v=1778419353","url":"https:\/\/brocantejolbro.com\/en\/products\/ancien-briquet-electrochimique-luminus-a-pile-de-grenet","provider":"Brocante Jolbro","version":"1.0","type":"link"}
