 This jar has sediment on the shoulder from where "the Gulf Stream Turns" as paleo-climate scientist Lloyd Kegwin told me around 2005. With melting ice and fresh water mixing with sea water and the dynamics of ocean/air circulation -- I can't write "where Gulf Stream turns" without wondering how this big circulation pattern will be changing.
The coordinates are written. Most of this piece's matte glaze was assembled from refined materials.

People who miss seeing my signature on the back will find it on the front here -- tucked in with other legible calligraphy among sediment glaze from where the Gulf Stream turns. (as I was told in 2005, but will it continue to turn there?)

Interior from center to midway was brushed with material from CDH10--the first retrieved sediment from the "Long Core Sea Trial" of 2007. An earlier Bermuda Rise sample that's very golden flowed over it and both, mixed together, pooled in the center.
Exterior says, "CDH10, 33° 41.199' North, 57° 36.903' West. 4,583 meters deep."

Very self-organized and very expressive in a chaordic kindof way. Atlantic inside, Pacific outside. Lots of writing on the exterior tells details of sediments' coordinates and the Pacific sample is from off Oregon at Hydrate Ridge.

Interior from center to midway was brushed with material from CDH10--the first retrieved sediment from the "Long Core Sea Trial" of 2007. An earlier Bermuda Rise sample that's very golden flowed over it and both, mixed together, pooled in the center.

Copper green glaze, assembled from refined materials, by itself on the back is green but on the rim, where it overlaps with white glaze, it made marroonish pinkish-red. This is a cue to how oxidizing and reducing atmospheres in the kiln work to create variety.

Exterior glaze is the most sandy sediment I have from a deep sea location of a thirty square mile area south of Martha's Vineyard. I apply it to leather-hard clay and stroke it off quickly at a time when I also write words into the clay.

Large size gives sediments lots of space to branch. The sediment was evenly applied and melted into the pattern -- with good fortunate of perfect temperature (not too hot and not too cold.)
Back band says, “No man [or woman] has earned the right to intellectual ambition until he has learned to lay his [her] course by a star which she has never seen — to dig by the divining rod for springs which she may never reach.”

 Some pieces say things that will never be repeated and they have a commanding presence that gets some point across. Some are rarely seen because they're tucked away, in case of a well-curated show. Here are some:
