The novel innovation in Cornelius\u00e2\u0080\u0099s lamp was its ability to burn lard and other concrete fat with a minimal amount of heat. This allowed lamps to use cheap lard for fuel instead of the costly whale oil that had dominated the lamp industry prior. The lamp used a deflector that heated a tube leading to the fuel, providing no more metal to heat the lard than was absolutely required. Cornelius\u00e2\u0080\u0099s lamp outsold those fueled by expensive whale oil, making his company the largest lighting company in America. Cornelius also attempted to perfect the daguerreotype photographic process, taking the first-ever self-portrait in 1839."}], "name": [{"label": "inventor", "content": "Cornelius, Robert"}], "place": [{"label": "associated place", "content": "United States: Pennsylvania, Philadelphia"}], "physicalDescription": [{"label": "Physical Description", "content": "fit together (base connector/connecting technique)"}, {"label": "Physical Description", "content": "fit together (reflector connector/connecting technique)"}, {"label": "Physical Description", "content": "fit together (reservoir connector/connecting technique)"}, {"label": "Physical Description", "content": "inserted (base connector/connecting technique)"}, {"label": "Physical Description", "content": "inserted (burner connector/connecting technique)"}, {"label": "Physical Description", "content": "inserted (push-up connector/connecting technique)"}, {"label": "Physical Description", "content": "inserted (reservoir connector/connecting technique)"}, {"label": "Physical Description", "content": "brass (base material)"}, {"label": "Physical Description", "content": "brass (burner material)"}, {"label": "Physical Description", "content": "brass (push-up material)"}, {"label": "Physical Description", "content": "brass (reflector material)"}, {"label": "Physical Description", "content": "brass (reservoir material)"}, {"label": "Physical Description", "content": "tin (base material)"}, {"label": "Physical Description", "content": "tin (reservoir material)"}], "dataSource": [{"label": "Data Source", "content": "National Museum of American History"}], "objectType": [{"label": "Object Name", "content": "lamp"}, {"label": "Object Type", "content": "Lighting Devices"}, {"label": "Object Type", "content": "Patent Model"}, {"label": "Object Type", "content": "Lighting Devices"}, {"label": "Other Terms", "content": "lamp; Lighting Devices; Oil"}]}}, "url": "edanmdm:nmah_304638", "hash": "96699d0f6136c7ec8116d8d3f3278800c98716c9", "docSignature": "693f3697ebaf7746a8ab9c2031ddbbc6", "timestamp": 1664882628, "lastTimeUpdated": 1664882550, "title": "Cornelius Solar Lamp Patent Model"}
