Brown glaze is from 26° 59.12° north, 91° 17.6° West and is more like something I want to wear as lipstick than any sediment I've touched since I began with seafloor mud 15 years ago! My affinity for it was so strong I used it on this bowl with no prior testing (and that's a rare risk).
The porcelain clay was so soft that four pressure points from my fingers dimpled the clay which later (in the kiln) caused the expanded molten colorless seaglass to rise up, merge with some color from the mud, and relax back down in a squarish shape. Rare risk, rare outcome.
