firing with seaweed

Hi all,
Last weekend we fired the anagama built by Phil Ahnen at the Rochester
Community and Technical College (Rochester MN) again. I experimented with a
wad of dried seaweed that came with some lobsters from the grocery several
months age. I tied a bundle of the weed to the side of a stoneware pot with
fine copper wire. It was fired facing the firebox, fairly close I think.
The pot got a huge 'growth' of frothly bubbly unsightly stuff on the side
where the weed was. A bit of the rim on that side appears to be melted off.
Is this due to fluxing by high seasalt content up against the pot, or is
there another explanation I am not thinking of. It is one of the pots that
qualifies to be called 'interesting.' There was no other pot that did this,
and the rest of the pots in the kiln looked generally fine (or great, some
wonderful students work in that program.)
Thanks,
Galen Schauer

If you don't want such strong encrustation, try soaking string in sea salt
and apply that to the pot. It might be interesting to wrap the copper wire
around the string as well.
I used to do cone 10 saggar firing using bananas and other organic materials
on platters and you can get that heavy encrustation. The brine soaked string
should give you what I think you're looking for.
