Click to read the numbers that can locate the source of this sediment glaze on a map. The sediment is from Orcas basin and is fine-grained, transparent (see exterior) and shows details of terrain in the porcelain clay's surface.
Copper and chromium color the matte and glossy green glazes on this bowl. Clear sea glass in the center foamed up when hot and dragged colorant from sediment back down in; that accounts for the dark area in the cooled glass center.

Exterior band says about interior marine sediment glaze, "Gulf of Mexico - salt-tektonics - oil - bluefin tuna habitat - outflow - co-evolving colonies." Writing was done into leather hard clay after applying same marine sediment thinly.
Other glaze is celadon, assembled from refined materials. Central; gull filled with clear sea glass -- this has subtle plays of texture and color I wish I could repeat on demand.

This has Orca Basin sediment thin and thick -- doing all it's good at doing. Writing is into a wash of it on leather-hard clay -- zoom in to see better.

Brown glaze is from 26° 59.12° north, 91° 17.6° West and is more like something I want to wear as lipstick than any sediment I've touched since I began with seafloor mud 15 years ago! My affinity for it was so strong I used it on this bowl with no prior testing (and that's a rare risk).
The porcelain clay was so soft that four pressure points from my fingers dimpled the clay which later (in the kiln) caused the expanded molten colorless seaglass to rise up, merge with some color from the mud, and relax back down in a squarish shape. Rare risk, rare outcome.
