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.

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" x 2.25"
Brown speckled glaze is from stony valley of Fyfield Downs. It's glacial sarsen. Green matte glaze assembled from refined materials. Center of sea-glass.
5.5" x 2"
On porcelain, interior of pumice/mud and exterior of M.A.R. basaltic rock slurry over a surface chattered when the bowl was leather-hard. Incised coordinates point to both sources. See more in the Havre Pumice/Mud category.
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.

On porcelain clay is the purest sample labeled "uber fabulous" by the geologist who gave me the ground rock that is melted into white rivulet glaze here. Rim and foot assembled from refined materials. Seaglass center.
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"
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.
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.

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.
5.75" x 2.25" Porcelain
Rarely does the play of color from oxidizing and reducing kiln atmosphere show so clearly as one copper glaze shifts from turquoise to red.
Brown glaze on front and back are both from Red Sea. Exterior from 1966 and interior from 2008, coordinates describe 2008 sample, thanks to a joint cruise of KAUST & WHOI. Sea a map of this area and a cell biologistís microscopy image and more.

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.

Sea-glass center, copper green trim assebled from refined materials. Sea a map of this area and a cell biologistís microscopy image and more.
5" x 1.5"
Sediment is applied thickly inside and is interacting with a piece of clear sea-glass. Exterior is same sediment applied thinly. Coordinates are written for this sediment glaze. Maps and more information in "Collected Mud Stories", thanks to Amy Bower, a WHOI scientist. Sea a map of this area and a cell biologistís microscopy image and more.

Says, "Monterey Bay, a seafloor ecosystem and a marine sanctuary mud -- melted here. Other glaze assembled from refined materials. Center of sea-glass.
5" x 2.25'
Made of porcelain clay, this bowl says, "Brazil Margin & Mouth of Amazon River where fresh water nourishes a salty sea". Interior brown is Amazon River sediment and golden strip on back is Brazil Margin sediment. Other glazes assembled from refined materials. Center of sea glass.

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.

Brown glaze is from four inlets in Glacier bay Alaska. Center of seaglass. Click for larger images and read words on the back.
6" x 2.25"
On porcelain clay. words say: Glacier Bay Alaska inlets named Reid, McBride, John Hopkins. It halso has Muir in the mix but space caused it to drop out. Seaglass in the center interacts with the sediment. Rim and foot glaze assembled from refined materials.
The shape of the bowl that determines what the sediment does is influenced by how I lift the soft clay off the wheel with four fingers (four bumps).
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.
