Magma Spewings of Basalt & Pumice
Magma Spewings of Basalt & Pumice

10" x 1.75"

My experience is of gleeful contrasts that we get this window into the forces of earth's molten material being metamorphosed into such contrasting forms. Mid-Atlantic Ridge rock is the basalty form and Havre volcanic pumice-mud is the silica-rich form. The rock slurry from Kane Fracture Zone is on the chattered pattern interior and back. Warm speckled areas are Havre mud.

The biggest submarine volcanic eruption known is Havre volcano. The deepest part of the world's oceans in the western Pacific is known as Mariana Trench -- it's about 1,580 miles long with an average width of 43 miles. It reaches a maximum-known depth of 36,070 feet at a small slot-shaped valley in its floor known as the Challenger Deep. The brown band surrounding the center on this bowl is from the Challenger Deep.

On porcelain from center outward, Havre pumice/mud, Mariana Trench, crushed blue seaglass, written provenance, Mid-Atlantic Ridge rock slurry, and more Havre volcano-mud.

Note that porcelain mugs are $20 more each than stoneware. Stoneware and porcelain cups are priced differently because stoneware is easier to work with and the translucency of porcelain also makes deformations (some are favorable, some are losses).

Crust Breaks Up & Reforms

4" x 3.25"

Interior is Havre volcano and exterior is Mid-Atlantic rock slurry. As it is with Earth's undulating seafloor it can also be on a potter's wheel. Collapsing clay sometimes (rarely) 'works' as dynamic assymetry. Hearing scientists in a submarine watching an eruption say, "Look the crust is breaking up and reforming!" causes me to grab these when they happen and glaze them with materials from geo-active sources
