Click to enlargeThis section includes Mid-Atlantic Ridge rock slurry (diverging plates), Costa Rican accretionary prism (subducting plates)and Snowball Earth. You might find some K-T Band here and in the "Crust and Dust" section. More detail at "Joan Lederman's Blog".

Some scientists think, and National Geographic confirms that 635 million years ago Earth was covered by ice or slush.

The items on this page are partly glazed with Namibian rock powder given to me by Bernhard Peucker-Ehrenbrink who gave me this link to learn about the sampling and the science.

Snowball Earth
Snowball Earth

8.75" x 4"

Says, "Snowball Earth a time and a place when 635 million years ago global glaciation says this melted Namibian rock." The rock slurry was applied thickly inside and thinly outside. The stoneware clay interacted with clay during firing and colored the glaze. Rim and foot of glaze assembled from refined materials.

Push/Pull and Snowball Earth

8.5" x 2"

Center of seag-lass framed by speckled brown area of K-T Band framed by chattered area of Mid-Atlantic Ridge rock slurry. Rim next to words is Namibian rock that, reportedly, proves glaciation at equator 600 to 700 million years ago.

Area under words is the Namibian rock, dripping and branching as it moves over the porcelain clay. Interior is shiny white, top exterior is matte white. Sea-glass dimple in lid.

Reduced price because glaze dripped and I filled an area with epoxy putty.

Galapagos, Red Sea, Snowball Earth, M.A.R. : Hot/Cold

13.5" wide x 2.75" high

Band of speckled warm-white on interior and exterior is Namibian rock that is evidence that Earth was fully glaciated about 700 million years ago. Red Sea is in the brown shiny glaze, lip of Galapagos and the chatter pattern is Mid-Atlantic Ridge rock slurry. Two fish in center, carved as a stamp by Alan Steinbach.

Rocks Flowing, Once Tumbled as Ice Melted, Now from Fire

13" x 3.25"

So many stories! Even the green glass center had been red glass before firing! (must have been the basalt granules causing a local reduction?) Transformation.

Says: Earth covered by ice 635 million years ~ still spinning ~ hard crust around a molten core. HERE: basalt and glass center framed by subducting residue, spreading crust, "ALL" mud and Namibia (arrow points to rock powder on the rim).

The back is "ALL" (dips into buckets from north, south, east, west plus siliceous and carbonate materials) applied thinly.

Glaze on rim that's matte white and green, assembled from refined materials.

Says, "Snowball earth 635 million years ago global glaciation .... says this melted slurry from Namibian rock layers. What sounds then."

Interior patterns is from how this rock slurry melted and flowed during firing. Center of seaglass. Exterior glaze broke away from clay surface reminding us how ice floes collect and separate. Shiny and matte whites are glazes assembled from refined materials.

The back is glazed with the same Lau Basin material whose coordinates are specified on the front.

There is a photo of the piece before firing that shows the center is red glass that turned green in the firing.

Dripping rocks!

Shoulder from the Cretacious Tertiary Boundary, when dinosaur-killing cloud of asteroid dust settles around the globe. It's this iridium that helps validate theories that Earth was covered with ice 600 million years ago. The Namibian rock from that era is slurry applied to the body of the pot here, named "Snowball Earth". Interior and exterior matte white (near base) are glazes assembled from refined materials. The rock slurry that rolled and beaded up during firing fascinates me and evokes curiosity about the sounds of whatever it was back then that lapped against shores (wherever THEY were back then).

EVIDENCE: Ceramics from Earth's Kiln and Mine

Some WOW stuff came from the kiln over twenty years of melting muds and rocks. Some I photographed and have assembled into a set of twelve cards you can see as thumbnails and a slideshow here. Cards are blank inside EXCEPT a thirteenth with a LEGEND inside -- it refers to numbers on each card.

NOTE about shipping: $7.50 is the cost of one in a Flat Rate USPS box but website only calculates UPS. If you need shipping, I'll subtract the difference between $7.50 and the UPS charge so you'll pay the lower cost. If you're buying multiple boxes, I'll probably use UPS; if in doubt, contact me.
