Our images this week show a zoomed-out view of the region of the ceramic sample containing the mullite “thicket” from last week. I am often struck by the visual similarities between SEM images, which show very small patches of a fired ceramic surface, and aerial photographs of geographic landscape. Cracks appear like roads or fissures in the ground; protruding crystals resemble hills, mountains, or volcanoes. Of course, in a very rough sense, […]
This week we feature another SEM image of the etched, fired ceramic surface we’ve been examining the past few weeks. This view looks into a small pit/cavity with an overgrowth of plate-like crystals jumbled together with needle-like (acicular) crystals. The needles are most likely composed of mullite, also known as porcelainite, an aluminosilicate material found commonly in fired ceramics. A scale bar of one micron (one thousandth of a millimeter) is shown in the […]
Last week we introduced the technique of Scanning Electron Microscopy (SEM) and posted an electron micrograph (SEM image) of a hexagonal alumina/hematite crystal formed in a “flashing” region on the surface of a ceramic vessel from an atmospheric firing. We noted that SEM is capable of capturing images with resolution much finer than the limit of optical microscopy, which is roughly a few hundred nanometers. In the gallery of images below, […]
Today’s featured image was obtained using a Scanning Electron Microscope (SEM). It shows a patch of micro/nano-crystals found on the etched surface of the sample discussed in last week’s post. For scale, the edge of the hexagonal platelet located just to the right of and above center is about ten microns (one one-hundredth of a millimeter). Those not familiar with electron microscopy may wonder why the image is monochrome and why we […]
Back to school season seems to be an ideal time to remind ourselves of Karen Atkinson’s popular session at the 2016 conference. Get Your $h!t Together and get your semester started right! Check it out below, and be sure to visit our YouTube channel for more conference session replays!
Have you ever wondered what causes “flashing” colors on bare clay in atmospheric (e.g. wood, salt or soda) firings?
Craft in America, the Peabody Awardwinning series, begins its eighth season on PBS with a unique hour that celebrates TEACHERS renowned individuals who are committed to their own artistic visions and are equally committed to sharing their skills and passion for craft with new generations of students and artists of all ages. As part of PBS’ Spotlight Education programming, Craft in America: TEACHERS premieres on Thursday, September 15th […]
Karen Karnes passed peacefully at home on July 12th, 2016. She was a towering figure of the postwar studio pottery movement, pioneering salt-glazing in the 1960s and wood-firing in the 1980s. Her work opened undreamed of possibilities of expression for the handmade pot. For the many potters who knew her, she was a mentor whose work embodied the creative power and singular voice to which we all aspire—her life in […]
NCECA hopes its members and the greater ceramic community have enjoyed continued access to the 2016 Fab Lab with the online rebroadcasts of the LIVE STREAMED conference sessions, culminating in today’s video of the final session on Friday afternoon, featuring Brooks Oliver: I am curious about ways in which new technologies can influence my process working with clay; and, vice versa, how my practice working with clay can impact my […]
With the support of 92Y Virtual Clay, Skutt Kilns, Shapeways, Anne W. Bracker, West Virginia University, and presenting artists, Clay Fab Lab represents a new conference experience with clay, touch, and technology. Emergence of new technologies and their application to ceramic art and learning represent exciting possibilities that will influence the field’s continued evolution in the 21st century. Many of these technologies are becoming more accessible and some are even DIY…
In the Venn diagram of my life, the spheres of Music, Movement, and Art collided at the 2016 Conference Opening Ceremonies. After listening to internationally renowned choreographer, Liz Lerman, speak about the art of critique, the crowd in KC was treated to a performance which combined ceramic elements in a unique Operetta. “Wit and Menace,” a work commissioned by NCECA for the popular Randall Session, included ceramic horns by Linda Lighton, two singers, a band of instrumentalists, a composer, […]
Del Harrow, Camilla Friedman-Gerlicz and Grant Landreth present approaches they are exploring through their own studio work with computer aided design and clay. This presentation will discuss methodologies and techniques for parametric modeling and hybrid digital/analog fabrication. Demonstrated processes will include Grasshopper parametric modeling for Rhino, CNC machining, and direct 3D printing clay. Friedman-Gerlicz and Landreth are both currently enrolled in the Special Student program at Colorado State University.
The Emerging artist deadline is quickly approaching. June 15. 2016 APPLY! Why not?!!! This is going to be a very important year as we embark on the 51st year of NCECA’s history and the beginning of the next 50, with the Portland Conference already taking shape as “Future Flux”. The process of creating and compiling the application and submitting the materials for this wonderful opportunity is an invaluable experience. NCECA’s Emerging […]
Having now spent several days in Gary Erickson’s studio and apartment as I help the family in closing out Gary’s professional life I find myself immersed not only in his work, but also in my memories of his life. I met Gary in 1992 when my new school, Concordia University, St. Paul, hosted an exhibition of his work after he had served as a sabbatical replacement for a term the […]
