LeeU Posted November 10, 2014 Report Share Posted November 10, 2014 This is part of a 5" unglazed porcelain piece pulled from the NHIA anagama firing last week. What are the hair-thin lines that have emerged across the surface? Thanks! Link to comment Share on other sites More sharing options...
bciskepottery Posted November 10, 2014 Report Share Posted November 10, 2014 Throwing lines, perhaps sponge marks left behind -- too fine to see unfired, but firing brings out the details. Same for your other picture. Link to comment Share on other sites More sharing options...
Biglou13 Posted November 10, 2014 Report Share Posted November 10, 2014 It's has o be something in the forming process. The line spacing is too regular to be a kiln affect. Too mechanical. If it is from the kiln then those are very special pieces. I'm trying to imagine how the contraction and expansion of clay, or kiln contribution would create this......

LeeU Posted November 10, 2014 Author Report Share Posted November 10, 2014 Thanks Biglou....turns out they are a cut-off trail. Link to comment Share on other sites More sharing options...
neilestrick Posted November 10, 2014 Report Share Posted November 10, 2014 Thanks Biglou....turns out they are a cut-off trail. You mean from trimming? Link to comment Share on other sites More sharing options...
synj00 Posted November 11, 2014 Report Share Posted November 11, 2014 Interesting. I notice even in oxidation when applying something like a semi transparent celedon it accents the throwing / trimming lines and even the indiscernable curvature of the form. I'm sure an iron oxide wash would accentuate the piece as well. Try to really compress the outside of the clay with a rib and or running a chamoi cloth over the piece at leather hard or even a sponge over the piece when its dried into greenware. It will take the edge off any imperfections. Or on the other side of it, make these suckers stand out even more and exagerate the lines! The sky is the limit! I think the lines look great myself!

LeeU Posted November 13, 2014 Author Report Share Posted November 13, 2014 I do ripped and torn sculptural slab work, and use a wire cutter through a wedged block of clay to give me the foundation. These lines were not discernible to the eye so they seemed to just "emerge" during the firing. The photo is highly enlarged for detail. I am so psyched about getting started on the resumption of my journey on a clay path!! Just from that one firing I have a dozen ideas and mini-projects. Not to come across like a groupie, but all my thanks go to John Baymore and Maureen Mills, who helped make this happen for me (the NH anagama firing), at the last possible minute.
