Further SEM study (see "microscopy 2") with the sample cut from the wood-fired lid has provided some images that provide novel evidence in support of our current theories regarding the microscopic physical processes that lead to formation of bright red color patches on the surfaces of wood-fired, reduction cooled stoneware clays. After seeing this new… Continue reading microscopy 3
Yesterday I started doing some survey optical microscopy to help select a sample or two to prepare for electron microscopy. It tends to work best to start with a piece that's already relatively flat, so I immediately thought about the top surface of the lid of this container: The above photos were just taken with… Continue reading microscopy 1
Last week I found some time to perform some preliminary studies on a sample of indigo-dyed cotton fabric. I first took some representative optical microscope images to get a sense of the distribution of dye in the cotton fibers. Below left is an image at 103x and on the right an image at 1010x. System… Continue reading indigo up close
