Day 12 of the NHIA anagama construction with my kiln class came and went today....... with most of us working from 9 AM until about 8:30 PM (along with torrential rain for cleaning up at the end of the day). Today was the "magic moment" wh...en the three sections of main arch forms came out and we officially had an "inside". Front firebox step arches started, more steelwork done, smoke chamber interior wall started, rear wall started, a bit more chimney added above the roof line before the rain, and horizontal flue connection to chimney worked on. Busy and LONG day.

Mark,

 

Thanks for the kind words.

 

The exact kiln useage is not yet fully determined.  We are working on that stuff.  Priority #1 is the degree programs needs, second is community education.  For the degree folks, there will be a minimum of one firing per semester.  There will eventually be access to the greater community via our Community Education program........ how that will work is not yet determined. Classes, workshops, visiting artist sessions..... not sure. 

 

The one thing that will not happen is any sort of "private kiln rental"; every kiln has a finite number of firing in it before it gets rebuilt (that # is assuming it is taken care of).  Every firing is REALLY expensive in terms of depreciation.

 

best,

Don't pack too tight.... they will have significant thermal lag....... since they are designed to be insulators. Stak in an open pattern to get the faces hot..... and burn off the junk. I'd go toe 1000-1100 F.

Wood firing....... the absolute MOST expensive way to fire. :rolleyes:  :)  B)

Babs,

 

Storage, not moderation. :)

 

Yes, the planning has taken an astronomical amount of time... no question about that.  There have been many revisions of the kiln itself, let alone dealing with the many revised plans for the foundation and building and the detail drawings for stuff like the roof penetration point and the flashing, and such. CAD is handy.... but it is not all as fast as people think.

 

The planned cycle is a four day firing for at least the first firing.  About 1 1 /2 to 2 days to 14, and then hold for about 2 days. So that is 3 eight hour shifts per day, for 4 days, or 12 eight hour shifts....... needing 4 people on each shift "team". 

 

I am the current "kama moto" (Kiln Master) for this kiln....... so I will not only be there for a lot of the total hours of the firing....... but for the periods I am not there trying to get some sleep.... I will be "on call" like a doctor.  I live only a 20 minute drive from the Sharon campus....... so that is easy to be there fast if needed. 

 

I will be in the "kiln master" role for the forseeable future.  I will be keeping track of the use of the kiln, and of course I'll sneak in a few pieces in every firing B) .

 

But you have to remember that I have a large wood kiln myself (slightly longer than this one) sitting in my back yard.  So wood firing is not such a "novelty" option for me.... it is what I always do.  But I think this kiln will be a "doozy" for results.  We'll see.

 

best,
