Research focus Title: Point micro-XRF data of Elizabethan burse
Research focus Category: Object/artwork
Research focus Description: Research focuses on the change of colour of metal embroidery of Elizabethan burse due to degradation, for PERCEIVE
Research focus Reference Image URL: https://collections.vam.ac.uk/item/O10808/burse-unknown/

Research Activity Type: Object Examination/Scientific analysis
Technique: X-ray fluorescence spectroscopy
Technique Category: Point analysis
Method Description: Point micro-XRF provides elemental information with high spatial resolution, allowing the interrogation of small details on museum objects without interference from neighbouring details. Within the PERCEIVE project, it has been used to obtain additional information on the composition of individual metal threads within the embroideries used to decorate the Elizabethan burse.
Tool / Equipment (or Software) Description: Bruker Artax micro-XRF (no longer commercially available)
XRF analysis was performed with an ARTAX micro-XRF spectrometer (50kV, 200uA and 600uA, Live Time 100s) equipped with a rhodium target. The spot size was less than 0.1 mm
ROI or target area or spot size: Individual areas of interest on metal threads with a spot size less than 100 μm
Examination Methodology: The XRF spectra were acquired in air

Object Examination Scale: Micro
Examination Class or Type: Single
Specific Scope linked to the Project: Development of a model for the virtual reconstruction of the original appearance of the metal embroidery
Measurable Entity / Property: Elemental composition
Material Category: Textiles
