From the SANSAI kiln

Post  Tom Benda on Wed Feb 24, 2010 8:12 pm

My 5th load
It didn´t turn out well. I don´t want to speak about the reasons by now.
I will add in this nr. 5 more pics of pots, when I fire this load one more time...
Here´s a little tasting of pots, which turned out well on the first occasion.
The greatest gift was "LIBUŠE 18.1.2010" which I made in the moment of grandma´s death...
So I signed it like that.
When I examined my "bad 5th load", grandma Libuška sparkled at me...





and some others:





and more in my webalbum

I had other firings last year and still with problems to reach top temperature. 6th load, 7th I tried for two times and this 8th load I had to fire for second try again yesterday. We forgot keeping the flames inside chimney and went for "bitch fox stern" :-).
I was very happy, everything worked like clock and I felt as a ceramist again, looking forward to the unloading.
But such a terrible view inside my kiln I had!!!

View from above



When reaching top temperature, we kept loading wood into fireplace and then we closed it. But a rocketflame went through the chimney! For half an hour, then fox stern the other half without loading wood! I´ve heard "it´s just a step from 1300°C to 1400°C" and now I could see it in my own kiln - which I couldn´t fire enough before!
After all calmed down, no flames out of chimney, I went to bed. I took a last look into the fireplace, saw just plasmatic hell.
In the morning I saw a shelf fallen down to the fireplace. That must have happend after I left my kiln.

There must have been absolute hell!



This pot hit a stand.
The pots didn´t brake by that accident, but they´ve just curved the walls. Ok - with small cracks, but on other pots I can see, that they´ve teared up, not cracked!
On the back batch of shelves I´ve seen some good pots. I´ll unload them tomorrow and take photographs immediatelly.

Hello Tom. What a pity about your last firing. The first pictures show some lovely pots. I would love a wood firing kiln but haven't the space. Keep going Tom and I'm sure we'll be seeing lots more in the future.

It ruined just itself :-), not my day, I was lucky - my kiln is a rude beast ! Very Happy
The problem was with too high temperature (Yes! Back again! :-) ) and one shelf´s bad predestination Rolling Eyes

Here are first photos from my dear wife, she just didn´t taky any front view... study






Dr.Greenthumb´s chamber pot


This one is exceptional for me - I refired my old pot, which I´ve used already...

Those colours are fantastic Tom. Is it mainly wood ash and temperature that creates the colours?

Tom - bummer about the falling shelf. I can relate. I once knocked the kiln sitter out of whack on my electric kiln the the temperature probalby reached cone 10++ as the pots melted and ruined some kiln furniture and shelves.


Here is Tom and my wife, Terry, next to his large wood kiln.





Inside the kiln.


I can't wait until you perfect your firing procedure and start on my large pot. I think the other potters will be surprised at the size of the pots that will be coming from your kiln.
Here are a couple of green pots that I photographed in your shop.



Large shallow pots too - drool.
Don't have to look to China anymore for cool shallow pots. Great for banyan style.

Maybe I could have a wood burning kiln in the garden. Have you got a sketch you could post Tom?

My best firing (- results, not "the quickiest") took just 8 hours, this "overdone" :-) firing 10 hours...

Will, the glazes were influenced by temperature and ash a lot this time. Not just glazes, my whole kiln is covered by lots of glass.
The colours come from metal oxides, carbonates... Just the very last one - the exceptional for me - walls "painted" just by fire!, upper rim glazed a bit.
My kiln for You :-)

"The exceptional" once again

Other pots:










Rob, thanx for photos and give Terry my regards. Next time You visit me I´ll fire my kiln :-)
