Like a dog shaking water off it’s fur, I shook off the archiving job I assigned myself and have diligently done for years. The rule had been to never mix samples together. I might place them next to each other and allow them to flow together but I never physically mixed them. I authorized an exception and ladled muds into one bucket named “All”. I used equal amounts from north, south, east, west, and then added some high carbonate (mostly from foraminifera shells) and high silica (from small opals in a north Pacific sediment).
Sediments came from Bower’s Ridge in the Arctic, Indian Ocean, Lau Basin near the Submarine Ring of Fire, Emerald Basin off Nova Scotia and the Mediterranean.
What happened? The mixture often defaults to a branching pattern, as many high carbonate sediments have done. Go to the ALL Mixing section of my on-line store to see some results. As with all glazes, results vary depending on the underlying clay body’s composition, firing temperature, application thickness and shape of the pot.
