XRD Analysis of Black Particles from Horton Ho 229 V3 Adhesive

Small black particle extracted from the urea formaldehyde adhesive layer of the Horten Ho 229 V3 and placed on a tiny spindle for analysis with XRD. The cross hairs in the image show where, exactly, the laser will focus on the small sample. If the sample produces a spectrum that is crystalline then it will rule out charcoal. If it's amorphous (having no crystalline structure) then it could be many things, including charcoal. This sample and others were amorphous. Analysis was carried out by Nicole Little at the Smithsonian's Museum Conservation Institute in 2013.
