Last week I was in Florence visiting my friends at Editech. This is the first established Italian company working on art diagnostics. They had an awesome office space 5 minutes from the famous city’s location “ponte vecchio.” Now they just moved to a – yet better place! an historical building facing Arno river, just 1 minute from ponte vecchio. So impressive and classy.
Well, today, coming back from holidays, I want just post on how to make slide mounts to observe tiny pigments’ particles coming from a painting’s sample. In this earlier post you learned how to take samples and make cross-section. Using a tungsten needle (this is among the thinnest needle you can buy) – I found affordable ones here – you can scratch tiny particles of pigments from the paint – under a stereo microscope – and put them onto a microscopy slide to be mounted with Cargille labs “meltmount” resin.
This video shows how to make slide mounts using Cargille labs “meltmount” resin. A good reading on preparing slide mount is
In this post I introduced you to the basic of polarizing microscopy and how to identify pigments using the slide mounts you just learned how to prepare. Enjoy! W.
