Outreach
As part of the R&D process for my current project, I recently delivered two outreach events with families and school children. We looked at micro fibre plastic under the microscope and discussed it’s implications on ecosystems and the environment.
Forensic scientist Pam Hamer was very helpful in suggesting ways to test the shedability of fibres from garments and came up with a quick easy and way for children to create their own ‘microscope slides’ using clear tape and a clear backing of OHP acetate. Polorised filters help to distinguish synthetic fibres such as polmeric ones from natural fibres such as wool and cotton. One identifying feature of some synthetic fibres is the fact that they’re hollow, identifiable at magnitudes of 10x or higher.
Towards the end of May, at Alexandra Park, I was joined my members of the Quekett Club (Dennis Fullwood and Paul Smith) and Friends of Alexandra Park to deliver a joint outreach initiative which looked at Diatoms, bugs and micro fibre plastic. Local families collected samples from the surrounding area and, in my case, looked for evidence of microfibres and examined fibres on clothing.
This month, I also delivered an artist talk and workshops to Year 6 students at Netley Primary School in Camden. I talked to the children about how my upbringing in the Dolomites has informed my artistic practice, especially in terms of environmental issues. I spoke about how I’m currently using microscopes as my artists’ tools to produce video outcomes that look at micro fibre plastics. I ran two workshops where we created our own microscopic slides using clear tape and acetate. We also talked about the importance of thinking and acting intelligently in order to protect the environment. I found the children to be very open to ideas of change in order to safeguard the environment.
Keyence VHX 5000 Microscope
Thanks to Matthew Armes, technical sales engineer for Keyence UK, who called round on Thursday to demonstrate the VHX-6000 Digital Microscope.
This is incredibly easy to use and is capable of real-time focus stacking.
Multi-angle observation by rotating the stage or tilting the lens up to 90 degrees means you don’t have the move the samples by hand. It produces images up to 1600 x 1200 – for higher res, automatic stitching is possible with the motorized stage.
Also good depth of field, embedded polarizing lens and really fast automatic focusing.
I had the opportunity to photograph some of my micro fibre plastic slides, melted snowflake and ice slides and lichens.

QUEKEX 2018
Captured irregular snowflakes (London 2018) on slides, one of which shows microfibre plastic which could be clearly seen during the melting process. It’s worth asking what sort of damage plastic fibres are doing.
Photos will be shown at the Quekett Microscopical Club Quekex exhibition at NATURAL HISTORY MUSEUM (foyer of the Flett Theatre), Cromwell Road, London SW7 5BD
Saturday 6th October 2018, 10.30am – 4pm
Invitation-only exhibition.
Analytical aspects of conservation
It was a privileged to meet Christine Sitwell, the National Trust paintings expert at her talk, Analytical aspects of conservation in painting, organised by The Quekett Club in the Natural History Museum yesterday. It was fascinating to hear her speak about the process of attribution in relation to the Rembrandt self-portrait at the National Trust’s Buckland Abbey in Devon.

Christine talked about how technology is used to identify different periods through examination of different layers (ground), pigment and varnish. Minute specs of paint – usually taken from a tear or from the side – are examined under the microscope. She talked about the value of real pigments (various periods) and the use of spectronomy to pinpoint elements such as pigments, cobalt, potassium, nickel, smelt.
I very much hope that they can also authenticate the Titan as the one missing from the series.
