To create a daguerreotype, a  silver plated sheet was given a light sensitive surface  coating of iodine vapour. After a long exposure in the  camera, the image was developed over heated  mercury and fixed in a common salt solution. The  image lies on a mirror-like surface and is best seen  from an angle to minimise reflections.The surface of daguerreotypes is delicate and easily damaged, so professionally finished images were presented in a protective case or frame.","physicalDescription":"Daguerreotype double portriat of two children, two girls, probably siblings. They are both seated and both wear check patterned dresses with matching cloaks. One is holding a book.","artistMakerPerson":[{"name":{"text":"Unknown","id":"A1848"},"association":{"text":"","id":""},"note":""}],"artistMakerOrganisations":[],"artistMakerPeople":[],"materials":[{"text":"glass","id":"AAT10797"},{"text":"copper","id":"AAT11020"},{"text":"gilt","id":"x30367"}],"techniques":[{"text":"daguerreotype","id":"AAT53530"},{"text":"tinting","id":"AAT53059"},{"text":"engraved","id":"AAT53829"}],"materialsAndTechniques":"Daguerreotype, glass, copper, gilt frame, engraved(?) case","categories":[{"text":"Photographs","id":"THES48910"},{"text":"Portraits","id":"THES48906"},{"text":"Children & Childhood","id":"THES48980"}],"styles":[],"collectionCode":{"text":"PDP","id":"THES48595"},"images":["2016JC4577","2016JC4576"],"imageResolution":"high","galleryLocations":[{"current":{"text":"LVLC","id":"THES49171"},"free":"","case":"DAG","shelf":"19","box":""}],"partTypes":[[{"text":"daguerreotype","id":"AAT127181"}],[{"text":"photograph","id":"AAT46300"}]],"contentWarnings":[{"apprise":"","note":""}],"placesOfOrigin":[{"place":{"text":"England","id":"x28826"},"association":{"text":"photographed","id":"x30151"},"note":"possibly"}],"productionDates":[{"date":{"text":"ca. 1840-1860","earliest":"1835-01-01","latest":"1860-12-31"},"association":{"text":"made","id":"x28654"},"note":""}],"associatedObjects":[],"creditLine":"","dimensions":[{"dimension":"Width","value":"70","unit":"mm","qualifier":"","date":{"text":"","earliest":null,"latest":null},"part":"width of gilt frame","note":""}],"dimensionsNote":"","marksAndInscriptions":[],"objectHistory":"","historicalContext":"","briefDescription":"Daguerreotype cased photograph, double portrait of two children, c.1840-60","bibliographicReferences":[],"production":"","productionType":{"text":"","id":""},"contentDescription":"","contentPlaces":[],"associatedPlaces":[],"contentPerson":[],"associatedPerson":[],"contentOrganisations":[],"associatedOrganisations":[],"contentPeople":[],"associatedPeople":[],"contentEvents":[],"associatedEvents":[],"contentOthers":[{"text":"children","id":"x31526"},{"text":"children's dress","id":"x47347"}],"contentConcepts":[],"contentLiteraryRefs":[],"galleryLabels":[],"partNumbers":["E.1160-1992"],"accessionNumberNum":"1160","accessionNumberPrefix":"E","accessionYear":1992,"otherNumbers":[],"copyNumber":"","aspects":["WHOLE"],"assets":[],"recordModificationDate":"2025-05-06","recordCreationDate":"2009-03-17","availableToBook":false}}
