Glazed top 1/3 to 1/2 with three coats of seaweed, and bottom half with Jungle Gems Obsidian, overlapping. Fired in a community kiln at cone 6. Had some issues with pinholing. The seaweed ran a lot more than I expected, though I like the effect next time I would try using less of it to see if it sticks better.
