Traditionally, most of the fashioning and polishing was accomplished using abrasive-charged discs and wheels that were turned on bow-driven lathes, with the holes being made with a bow-driven drill. Most of the carnelian raw material is routinely subjected to heat-treatment to dry it and to permanently intensify the colour.","physicalDescription":"A collection of round buttons of varied size and form, in varying shades of orange, each with a single drill hole. One has radiating channels carved into the dome which widen as they run to the circumference. Two are flat discs with bevelled edges. Seven are small and similar in appearance.","artistMakerPerson":[],"artistMakerOrganisations":[],"artistMakerPeople":[],"materials":[{"text":"agate","id":"AAT11135"},{"text":"carnelian","id":"AAT133223"}],"techniques":[],"materialsAndTechniques":"Agate and carnelian, cut and polished using abrasives probably with the use of a bow-driven disc, drill, lathe or wheel.","categories":[{"text":"Clothing","id":"THES48975"},{"text":"Costumes","id":"THES269529"},{"text":"Gemstones","id":"THES270329"},{"text":"Hardstone","id":"THES270137"},{"text":"Jewellery","id":"THES48930"},{"text":"India Museum","id":"THES286062"}],"styles":[],"collectionCode":{"text":"SSEA","id":"THES48598"},"images":["2015HT3604"],"imageResolution":"high","galleryLocations":[{"current":{"text":"005","id":"THES374491"},"free":"","case":"","shelf":"","box":""}],"partTypes":[[{"text":"Buttons","id":""}]],"contentWarnings":[{"apprise":"","note":""}],"placesOfOrigin":[{"place":{"text":"Madras","id":"x31964"},"association":{"text":"made","id":"x28654"},"note":""}],"productionDates":[{"date":{"text":"c. 1850","earliest":"1845-01-01","latest":"1854-12-31"},"association":{"text":"made","id":"x28654"},"note":""}],"associatedObjects":[],"creditLine":"","dimensions":[{"dimension":"Diameter","value":"14.8","unit":"mm","qualifier":"","date":{"text":"12/06/2015","earliest":"2015-06-12","latest":"2015-06-12"},"part":"Grooved button","note":""},{"dimension":"Height","value":"4.8","unit":"mm","qualifier":"","date":{"text":"12/06/2015","earliest":"2015-06-12","latest":"2015-06-12"},"part":"Grooved button","note":""},{"dimension":"Diameter","value":"2.0 to 2.5","unit":"mm","qualifier":"","date":{"text":"12/06/2015","earliest":"2015-06-12","latest":"2015-06-12"},"part":"Flat button","note":""},{"dimension":"Thickness","value":"2.7 to 2.8","unit":"mm","qualifier":"","date":{"text":"12/06/2015","earliest":"2015-06-12","latest":"2015-06-12"},"part":"Flat button","note":""},{"dimension":"Diameter","value":"8.5 to 8.6","unit":"mm","qualifier":"","date":{"text":"12/06/2015","earliest":"2015-06-12","latest":"2015-06-12"},"part":"Small button","note":""},{"dimension":"Height","value":"3.5 to 4.0","unit":"mm","qualifier":"","date":{"text":"12/06/2015","earliest":"2015-06-12","latest":"2015-06-12"},"part":"Small button","note":""}],"dimensionsNote":"","marksAndInscriptions":[],"objectHistory":"Formerly in The India Museum in London and transferred to the South Kensington Museum (later renamed The Victoria & Albert Museum) in 1879.","historicalContext":"","briefDescription":"Buttons, ten in a bag, carnelian and agate, for costume, Madras India, c. 1850","bibliographicReferences":[],"production":"","productionType":{"text":"","id":""},"contentDescription":"","contentPlaces":[],"associatedPlaces":[],"contentPerson":[],"associatedPerson":[],"contentOrganisations":[],"associatedOrganisations":[],"contentPeople":[],"associatedPeople":[],"contentEvents":[],"associatedEvents":[],"contentOthers":[],"contentConcepts":[],"contentLiteraryRefs":[],"galleryLabels":[],"partNumbers":["08578(IS)"],"accessionNumberNum":"08578","accessionNumberPrefix":"","accessionYear":null,"otherNumbers":[],"copyNumber":"","aspects":["WHOLE"],"assets":[],"recordModificationDate":"2025-04-12","recordCreationDate":"2009-06-25","availableToBook":true}}
