A life time ago I was a ceramicist among other art things. And one thing I love todo was a Seaweed firing. I would say its easier than his method, but i can see his to be more convenient.
All you need for a seaweed firing is a beach with a good amount of seaweed.
You start by building your fire with your ceramics in the center.
Placing some kindling, paper, small sticks, a standard camp fire type of thing.
Then some dry seaweed on top to make a mound.
Once everything has taken light you can add wet seaweed on top, covering the mound.
The idea being, that as the fire goes it drys out the fresh seaweed then combusts it. And you keep that cycle going for as long as needed.
You can add air tunnels if needed. Windy days are much better as you can really get a inferno going in there.
I've managed to get temp's over 1300 degrees.
Firings can last days for very large ones (size of a truck), my longest it about 8 hours or so (size of a office desk).
