Unloading the New Kiln, Future Firings

The first firing of this little wood kiln went pretty well. There were a few good pots, a lot of mediocre pieces and some interesting things to look at. Sure, I can say I wasn’t expecting any super-fantastic results, but honestly, unloading this firing was a “learning” experience in many ways. I wasn’t totally sure what to expect, as I’ve never done a Cone 5 firing in a wood kiln (intentionally anyway…). There aren’t a lot of other clay artists doing Cone 5 wood firing, especially in this type of wood kiln, so I really wanted to investigate it.

There were at least 6 different clay bodies in the kiln that I thought would be interesting in a Cone 5 wood firing. I mixed up various batches of the local “Brickyard Red” clay, my backyard clay and some other California clays including mostly Newman Red, Muddox, and Lincoln Fire clay. The front of the kiln got up to cone 5 and the back (chimney) got up to about cone 1 or 2. I’m really happy about performance of the kiln, especially considering it was the first firing and excess moisture from the masonry can really hinder the temperature from rising. The whole firing took about 18 hours.

The majority of pieces fired in the kiln were flower pots, planters and other “peasant-wares” that I was willing to sacrifice for the sake of an experimental firing. I had a few new things I’ve been working on as well, including some bonsai trays and wall pieces. The pots that turned out well are now available to purchase for reasonable prices at Mad River Gardens in Arcata.

I was able to stack quite a few pieces in the chimney of this kiln, as I’ve done with many other kilns. The area inside the chimney is not typically used as a stacking space in most kilns but I’ve been able to refine this technique through years of designing, building and firing kilns. I’m usually pretty happy with the results as I don’t expect a whole lot from it, but it can significantly enlarge the kiln while making the overall firing a lot more efficient.

The next firing will be an old fashioned, rip-roaring, full blast Cone 12+, blanketing the pieces in flashy surfaces and natural wood-ash glazes. My clay work hasn’t focused much on this for a few years, so it’s time to revisit it. Hopefully, the results of the next firing will be good, because I’m planning a public kiln-opening that coincides with the North Coast Open Studios on June 4 and 5th. The kiln will be opened and unloaded at 10 a.m. on June 4th.

Below is an example of what is possible at higher temperatures. The surface of this piece has been painted by the fire and is a result of the natural wood ash glaze that happened during the firing. Hopefully, the next firing will have similar results.

New Kiln Finished & Fired

I finished the little kiln a few weeks ago, loaded it and finally fired it off, on Mother’s Day. So, accordingly, this first firing is dedicated to mothers. Not just my mom, but moms everywhere – including but not limited to “Mother Earth”. So take a minute to honor thy mother, and think – where would we all be without our moms? I can’t even fathom the number of poorly crafted & ghastly creations I’ve made but my mom said she liked them anyways.

Alrighty then, getting back to the point…. The first firing was mid-range; to about cone 5. Although this is a bit cooler than a typical wood firing, the local clay we’ve been using looks really good at this range and is a nice “brick” red & it saves a lot of BTU’s so it’s a win win situation.

Here is the kiln loaded & bricked up, with a propane burner on to pre-heat. The fiber chimney extension is removable to allow work to be loaded in from the top of the chimney in order to increase the stacking space.

For such a little kiln, it really seemed to swallow up a lot of work!

Here’s the kiln being fired off, sometime around midnight.

The kiln really fired like a gem & seemed to be quite efficient, so it should be pretty eco-groovy compared to some other wood kilns I’ve fired. During the “drying out” stage the kiln steamed for several hours, seeming to hold the temperature down a bit (it even continued to steam after the firing was done!). This first firing lasted about 18 hrs. , burning about a ½ cord of wood & a bit of propane. I can’t wait to unload it…..

New Kiln Under Construction

After months of preparation, I have finally broken ground on a new kiln, at our wonderful new home. Since moving in October of 2010, we have undertaken an extensive amount of projects both inside and outside. We have a lot to be thankful for, but I think the most exciting and luxurious aspect of being a new home owner is our new studio space! To start with, we walled-in the existing carport to make large shed that we now refer to as “the barn.” We then upgraded the detached garage with insulation, drywall and a 100 amp subpanel, while also rewiring our new “barn” for an electric kiln and more outlets. Then, we poured a new concrete walkway between the two buildings and added a level kiln pad on an otherwise steep hill. So, to say the least, there was a lot of preparation taking place in the last few months in order to set up the new studio to be as efficient and comfortable as possible, within a modest budget.

Here is a partial “chimney” and foundation of the kiln.

The new kiln will be designed use the chimney as an additional stacking space, in order to maximize the efficiency of the firings.

Here is the arch form in place, waiting for the bricks to be laid. I have been salvaging used firebrick for over a year to help lower the cost of the kiln, as it’s difficult to find a good firebrick for less than $4.50 a piece here in Eureka, where, coincidentally, gas is also at about $4.40 right now. This little kiln requires about 1000 standard firebricks, so by getting them for free, I’m saving quite a bit. I’m really excited about the kiln and the shape of it as its’ been a while since I’ve been able to build a kiln that is dug into a hillside. At this point it looks a little ghetto-ish, but I’m not afraid to say that is kind of my specialty. Anyway, we’ll see how it fires….
