Guldagergaard week 3 – Soda Time

Sunday, October 3rd, 2010

It’s been a very busy week, but then again, I suppose nearly all of my weeks here have been and will be very busy. With only five week here, time seems to go by so quickly.

Anyway, the first half of this week was consumed by finishing every possible sculpture I could, so they could be soda fired. The plan was to load the big bisque kiln on Monday, giving it plenty of time to cool before we loaded the soda on Thursday.It’s been a bit rough doing my main firing only 3 weeks into my time here, but fellow artist Jody was about to return to Canada, meaning if we wanted to fire together we had to fire this week.  It’s worked out for me though, since I managed to finish 90 flying beasts, which wasn’t far from my goal of 100.

Unloading the bisque

So after about a full week of last minute frantic studio work, Jody and I loaded up the Guldagergaard wood-soda kiln on Thursday. The kiln is a small little beast, with a capacity of 300 liters/ 10.5 cubic feet. It’s also a very different type of kiln for me, since I’ve only really fired an anagama and a train kiln.  This guy is a cross draft kiln, with a firebox located underneath the ware chamber. It’s weird.  It wasn’t like stoking a firebox, it was like stoking a conveyor belt. It wasn’t so much much a rhythm of “stoke, see how the temperature responds, adjust”, as it was a constant process of stoking, gradually pushing the wood further in the the kiln, and constantly adjusting.  It was like switching from a Sousa march to one of the Bach cello suites. Looking around online, it visually looks a bit similar to the “phoenix kiln” in a book by Jack Troy, which was mentioned on Carl Gray’s website. The main differences are the fact that the firebox has a flat, not arched roof, and the chimney is on the side, not the front.

Anyway, due to some last minute kiln maintenance work, we didn’t get the kiln started until about 9pm on Thursday night. The plan was to fire for about 20 hours, waiting to put the soda into the kiln until cone nine on the bottom of the kiln had fallen. Sounds good, as far as plans go.  However, life is seldom that simple. By hour 22 or so we had cone 9 down on the top, but had barely moved cone 8 on the bottom. It took easily another 4 hours of struggle before finally dropped the lower cone nine, by which point we’d also dropped cone 11 on the top of the kiln.  In all, the firing took us 28 hours, which was pretty exhausting for just two people, especially since we were also constantly splitting  more wood.

Richard prepping the soda bombs

Richard, the tech, had to leave for the night before we were ready to put the soda in the kiln, but here’s a shot of him explaining the soda balls to us. We were using a method developed by Gail Nichols, generally referred to as soda balls/bombs/burritos.  In previous soda firings that I’ve done, people have used the more traditional method of spraying in a mixture of water, soda ash, and sodium bicarbonate into the kiln. However, it seems like Nichols’s soda bomb method is taking off, which is understandable if you’ve seen how amazing her work looks. Basically, you mix soda ash, sodium bicarbonate, and whiting together, and add just enough water to form it in to balls. These balls then solidify to rocks, which you then dump into the firebox.  The soda then vaporizes in the firebox, distributing itself around the kiln.  I haven’t done much soda firing, but I would love to play around with it some more if the results from this firing are promising.

Anyway, at this point, we’re stuck waiting for the kiln to cool, and catching up on sleep. I’ll let everyone know what the results look like once we unload it!

Kiln Unloaded and Off to NCECA!

Tuesday, April 7th, 2009

We unloaded the kiln on Saturday, and it looks like a great firing. I’ve spent the last two days trying to clean up all of the work, and sort it as to where it will be going. Most of the beasts came off of their wads cleanly, meaning there wasn’t too much work to do as far as that. What was harder was deciding where each piece should go. I’ve set aside four to submit to jurried shows, another four or five to send to a show in Idaho, about 10 to take with me to Japan, and another 10 to 12 that will be for sale online. They’ll all be showing up online at around noon (PDT) on April 18th – so if you feel like buying a piece, check back near then!

I’m also finally all packed up for NCECA. I’ll be spending four days there, and then camping in the area with my dad, my brother, and my brother’s wife. It should be a lot of fun!

Back from the firing.

Sunday, March 29th, 2009

I’m back from the woodfiring, and have finally had a chance to relax, and get caught up email and so forth.  Overall, I feel like it was a pretty solid firing.  There were no crisis and no drama.  Everything went as planned.  We dropped cone 13 in the front of the kiln, and were probably in the cone 12 range in far back section of the kiln.  That’s fairly standard, and where we like to be.  We kept front of the kiln over 2300f for a day or two, though we would have liked the back to be hotter.  It was generally in the 2100′s for the last couple days, seldom staying in the 2200′s, which would have been nicer.  Regardless, there’s not too much point in speculating until we unload it on the 4th.

It’s going to take a few days for me to sort and clean all of my new work.  I need to decide which pieces will be traveling to Idaho for a show at the Art Spirt Gallery, and which pieces will be coming with me to Design Festa in Tokyo.  However, it’s my goal to to have all the photos go online, and new pieces for sale on the 18th.  I’ll post more information after I’ve unloaded the kiln.

All my firing photos are up on flickr now.  Enjoy!

Firing, end of day 4

Friday, March 27th, 2009

By the end of the firing, everyone ends up so very tired. This is the last night. We’re just working on maintaining temp, especially in the back of the kiln. We’ve dropped cone 13 in the front, and it looks like cone 13 in the far back might be soft. It’s hard to tell, since cone 12 reacts to the ash or something, and doesn’t melt like it should.
Tomorrow morning, we’ll mud up the kiln, and reduce cool it for a few hours. That will probably start in about seven hours.
Here’s a photo of the wood at the start of the firing, and how it is now. We got a whole brand new cord of wood that’s unstacked in the “after” photo.
The other photo is of the night crew. They’re good folks.

Firing day 3

Thursday, March 26th, 2009

Day three went smoothly as well. I’ll give more details tomorrow, it’s been a long day… Here’s the short version

*spent the day fighting to get the back temp up. Fairly standard for day three. Front was in the 2300s, but the back was back to the 2100s.

*Teabowls were pulled from the front of the kiln in a sort of high temperature raku. Lots of folks came to watch.

*used a lot of wood. We got another cord delivered, and have used about half of the sidestoking wood split so far

*Got to see two of those noisy barred owls fly right past me. Awesome.

Firing, Day 2

Tuesday, March 24th, 2009

The firing is going along smoothly. Yesterday evening, we had a bunch of trouble with wet wood. Between noon and 6pm we just hung out between 800 and 900f, fighting to try and get it to rise. However, we found some dry stuff eventually (under the cords of wet wood we’d stacked infront of it on Saturday) and got the temp up to 1300 in a couple hours.
Since then thing have been going smoothly. They did body reduction during the graveyard shift – putting the kiln into heavy reduction to pull iron oxide (and others) to the surface of the pots. They also started side stoking today, so there’s more to do. Luckly we’re well set for side wood for now!

Firing, day 1

Monday, March 23rd, 2009

We lit the kiln at about 9pm last night, with the loading wrapping up smoothly. We keep the temp to a rise of 50 degrees an hour for the first 1500 degrees or so, which can be tricky. The kiln will want to take off at first. At this point the fire is outside the front of the kiln, with the flames being pulled up through the kiln. This also useful to keep warm!! It gets cold up here! However tomorrow night will be the cold one – the fire will be inside the kiln, but the kiln won’t be hot enough to give off radient heat yet. The kiln is a giant physical mass of bricks, and it will take a lot of time and a lot of heat to get those suckers warm.
I have a photo of Anthony lighting the fire, and of Rick feeding it, last night at 300f. The next photo is Beverly, this morning at about 800f.

Loading

Sunday, March 22nd, 2009

We’re well into the second day of loading the kiln. Loading is always the slowest part of the firing, getting every piece just right. We also have a number of difficult pieces to load this time. Eric Nelson is leaving some pieces to be fired with us, and they’re so delicate and complex that they’re pretty tough to get into the kiln. I’m guessing we’ll be starting it around midnight.

Off to the woodfiring

Friday, March 20th, 2009

Tomorrow morning, I will be heading off to my thrice yearly anagama firing. We’ll spend Saturday and Sunday loading the kiln, and start up the fire Sunday night. When will depend on when we get done loading. In the past we’ve started it at times ranging from 6pm Sunday to 3am Monday. Hopefully, it won’t be anything nearly so late as that.
Right now, it looks like I’ll be working the swing shift, 4pm to 12:30am. The schedules are still a bit amorphous, but I hope it works out like that. There’ll be nine of us, working three different shifts. We’ll fire for about 110 hours, shutting it down some time on Friday.
I’ll try too keep things updated on the blog, and I’ll also keep things going on twitter as well! Off I go!

First of the new pieces up!

Monday, November 3rd, 2008

I’ve spent the last 48 hours rushing to get off an application for an “Emerging Artist” grant. Now, the light box is finished, a first round of work is photographed, and the CD with my images is burned and in the mail.

I’ve only had time to photograph a few of my favorite pieces, and looking through the results, I think I’ll be doing a few more tweaks to the lighting set up.  I’m pretty happy with it, but I feel like fussing with it a bit more.  Once I have all the information on the new critters up, I’m hoping to put together a howto on building the lighting softbox.

I’ll have my work cut out for me with documenting all of my beasts, though.  I’ll need to photograph them, record all the useful info for them, and price them.  I’ll also have to decide which to send off to galleries, which to sell myself, and which pieces will be not for sale, reserved to enter into shows.  Hopefully, I’ll have all of that worked out by the end of the week.  In the mean time, I’ve uploaded some of the photos I shot today.
