Treasure Island: A Forensic Investigation of a City
Over 200 experiments and fragments analysed from objects and sites ranging from 30 - 550 years old.
Kubisa's sophisticated use of the confocal laser microscope technology has become her fine art tool of discovery. Kubisa developed a unique use of this technology after observing neuroscience experiments. It was her understanding that
fluorescence present in older fragments will reveal unique
structures and evidence of the objects worn and absorbed life
Colour is selected in the data processing and laser collection of nformation. Then
processed by recutting through the collected layers from the laser and arranged by Kubisa.
Experiments and confocal laser microscope
Samples from artefacts and locations can be as small as 1 millimetre. They are collected at the time of discovering and recording the memory and history of the object or site. Samples have to contain fluorescence – this is present in objects that have existed for over thirty years. When viewed under the confocal laser microscope laser beam, Seran selects the areas to image based on composition, colour, and visual quality of the resulting fluorescence. Selecting which part of a samples fluorescent “rainbow” to analyse (from ultraviolet, through the visible colours out to infra-red) is crucial for the interpretation of the raw digital data collected. Seran also looks for fluorescent patterns that result from the innate properties of the materials itself and the wear and tear and accumulation of additional substances relating to its history. This can open a window onto the entire life of an object.
