'Calcedonia' glass was developed on the Venetian island of Murano around 1450. It was called after chalcedony, a naturally occurring hardstone. Details concerning its manufacture were kept secret for many decades. It involves mixing many different colours of glass in layers as well as a special heat treatment during blowing.","physicalDescription":"","artistMakerPerson":[{"name":{"text":"Unknown","id":"A1848"},"association":{"text":"","id":""},"note":""}],"artistMakerOrganisations":[],"artistMakerPeople":[],"materials":[{"text":"glass","id":"AAT10797"}],"techniques":[],"materialsAndTechniques":"Calcedonio glass","categories":[{"text":"Glass","id":"THES48946"},{"text":"Drinking","id":"THES48965"}],"styles":[{"text":"ITALY","id":"x29304"}],"collectionCode":{"text":"CER","id":"THES48594"},"images":["2006AP1171","2011FD2425"],"imageResolution":"high","galleryLocations":[{"current":{"text":"131","id":"THES49882"},"free":"","case":"9","shelf":"3","box":""}],"partTypes":[[{"text":"Ewer","id":""}]],"contentWarnings":[{"apprise":"","note":""}],"placesOfOrigin":[{"place":{"text":"Venice","id":"x29237"},"association":{"text":"made","id":"x28654"},"note":""}],"productionDates":[{"date":{"text":"1500-1525","earliest":"1500-01-01","latest":"1525-12-31"},"association":{"text":"made","id":"x28654"},"note":""}],"associatedObjects":[],"creditLine":"","dimensions":[{"dimension":"Height","value":"21.4","unit":"cm","qualifier":"","date":{"text":"","earliest":null,"latest":null},"part":"","note":""}],"dimensionsNote":"Conversion size only","marksAndInscriptions":[],"objectHistory":"","historicalContext":"","briefDescription":"Jug, blown calcedonio glass, Italy (Venice), 16th century","bibliographicReferences":[],"production":"","productionType":{"text":"","id":""},"contentDescription":"","contentPlaces":[],"associatedPlaces":[],"contentPerson":[],"associatedPerson":[],"contentOrganisations":[],"associatedOrganisations":[],"contentPeople":[],"associatedPeople":[],"contentEvents":[],"associatedEvents":[],"contentOthers":[],"contentConcepts":[],"contentLiteraryRefs":[],"galleryLabels":[{"text":"EWER\r\nAbout 1580-1600\r\n\r\nVenetian glassmakers were renowned throughout Europe for their skill.
