I don't have lots of sizes but can choose what works for your purchase. Put one in the cart and I'll manage the sizing or buy them yourself at Aftosa -- but they have a minimum order.
5" x 2"
Click to read and search to learn. On porcelain clay, interior brown is the Antarctica sediment glaze. Back is glaze assembled from refined materials. Center of sea glass.
4.5" x 1.5"
This one has a band from the Mariana Trench, cruise named "Challenger Deep". Chatter pattern is Mid-Atlantic ridge and exterior, rim and center are submarine volcano's pumice-mud from Havre eruption. Foot glaze assembled from land-based materials.
6" x 2.5"
Dark brown is Penobscot Bay sediment and warm speckled glaze is from Muscongus Bay. Center of seaglass. Rim and foot of glaze assembled from refined materials.
5" x 1.75"
Brown glaze on front and back is a sample taken from where Stonehenge stones once were. Green glazes assembled from refined materials, center of sea-glass that overlaped athe copper glaze.
5.75" x 3"
Seaglass sprinkled in center of bowl over a blue brushstroke colors the otherwise thinly applied pumice/mud from the Kermadec Trench's volcanic eruption of 2012. See more in the Havre Pumice/Mud category.
6" x 2.25"
On porcelain, Earth crust slurry is brown glaze on the back. Interior is a copper red glaze assembled from refined materials. Copper volatilizes during firing and the areas of green and red show the air circulation that carried that copper through the kiln's chamber at high temperature.
5" x 2.5"
On porcelain clay, a good example of how the Costa Rican Accretionary Prism sediment looks when applied thinly and thickly. Center of seaglass. Rim and foot glazes assembled from refined materials.
5" wide x 2" high
I found a little split in the rim -- still sound but definitely a flaw.
6" x 2"
With coordinates. Rock slurry is thin and transparent on the back, applied more thickly on the interior chatter-patterned area. Glazes assembled from refined materials are celadon and copper green (Oribe).
5.75" x 2.25"
From the exit of the Rhone River, where outgassing made geoclutter are words passed to me with the bag of sediment that is very sensitive to application -- it reveals details of the clay underneath like few others do.
3.5" high x 4.5" wide
On porcelain, exterior is Red Sea. Interior is a copper glaze assembled from refined materials. Sea a map of this area and a cell biologistís microscopy image and more.
5" x 2"
Sea-glass center, copper green trim assebled from refined materials. Sea a map of this area and a cell biologistís microscopy image and more.
9" wide x 3" high
On porcelain. Pool in bottom is same sediment--one even application. Coordinates on back. Cruise R/V Knorr-158-4 Multi-Core #60.
8" x 3.5"
Evenly applied North Atlantic sediment. Coordinates on back. Cruise R/V Knorr-158-4 Multi-Core #60.
6" x 1.75"
Back side is the silica-rich pumice-mud from the eruption of submarine volcano at Havre. Earth's magma from Mid-Atlantic rock slurry is the brown basalt-like glaze on the chatter-patterned surface inside the bowl.
Other glazes, copper green and shiny brown were assembled from refined materials. Sea-glass center.
4.75" x 2.5"
On porcelain clay is the sediment glaze from Ashkelon Excavations. Copper green glaze assembled from refined materialks. Sea-glass center.
