Her extensive research into the properties of this metal and her fine appreciation of colour and line combine in the subtle colours and shimmering textures achieved in this brooch. \r\n\r\nTo create this effect the aluminium is first anodised by immersing it in a solution of sulphuric acid and water then passing an electric current through it. This forms a thin surface film of aluminium oxide which is very tough yet has microscopic pores which enable colouring dyes to be absorbed. After dying the surface is sealed. Shapes for jewellery are cut from the dyed and sealed sheet, and these are then compressed in a rolling mill, adding texture or crazing to the surface. As anodised aluminium cannot be soldered the assembling of a piece often requires the addition of minimal wires and findings to the design.","physicalDescription":"Long, narrow brooch made from two overlapping pieces of anodised aluminium that have been etched, dyed and crazed. The upper flap has a striated pattern in purple and ochre, the lower in red and ochre. The inside surface is decorated with gold leaf.","artistMakerPerson":[{"name":{"text":"Adam, Jane","id":"A22155"},"association":{"text":"designer and maker","id":"x34662"},"note":""}],"artistMakerOrganisations":[],"artistMakerPeople":[],"materials":[{"text":"aluminium","id":"AAT11015"},{"text":"gold","id":"AAT11021"},{"text":"stainless steel","id":"AAT10920"},{"text":"silver","id":"AAT11029"}],"techniques":[{"text":"anodizing","id":"AAT54025"},{"text":"etching","id":"x39131"},{"text":"dyeing","id":"AAT53049"}],"materialsAndTechniques":"Etched, dyed, anodised and crazed aluminium, with moon gold leaf, silver and stainless steel","categories":[{"text":"Jewellery","id":"THES48930"},{"text":"Accessories","id":"THES48998"},{"text":"Metalwork","id":"THES48920"}],"styles":[],"collectionCode":{"text":"MET","id":"THES48599"},"images":["2008BT1616"],"imageResolution":"low","galleryLocations":[{"current":{"text":"91 (VA)","id":"THES49703"},"free":"","case":"41","shelf":"A","box":"5"}],"partTypes":[[{"text":"Brooch","id":""}]],"contentWarnings":[{"apprise":"","note":""}],"placesOfOrigin":[{"place":{"text":"London","id":"x28980"},"association":{"text":"made","id":"x28654"},"note":""}],"productionDates":[{"date":{"text":"2000","earliest":"2000-01-01","latest":"2000-12-31"},"association":{"text":"made","id":"x28654"},"note":""}],"associatedObjects":[],"creditLine":"Given in honour of Elizabeth Goring","dimensions":[{"dimension":"Height","value":"12.86","unit":"cm","qualifier":"","date":{"text":"","earliest":null,"latest":null},"part":"","note":""},{"dimension":"Width","value":"1.53","unit":"cm","qualifier":"","date":{"text":"","earliest":null,"latest":null},"part":"","note":""},{"dimension":"Depth","value":"2.05","unit":"cm","qualifier":"","date":{"text":"","earliest":null,"latest":null},"part":"","note":""}],"dimensionsNote":"","marksAndInscriptions":[],"objectHistory":"","historicalContext":"","briefDescription":"Folded brooch made from etched, dyed, anodised and crazed aluminium, with moon gold leaf, silver and stainless steel.
