Soda fired in the Kootenays

Wow, Almost a whole year has slipped by since I posted anything. So, not to bore you with the reasons why I have been so remiss in keeping this updated, I will instead show off a few pots that came out of a very special firing that I took part in at the beginning of September. The Alberta Potters Association organized a pottery retreat to fire Robin Dupont's train kiln, but Mother Nature had other ideas. For most of the summer, it appeared as though British Columbia was all on fire and as bad luck would have it, Robin lives smack dab in the middle of the Kootenays where a lot of the fires were located. That didn't stop us though. Plans were changed, and we fired his soda kiln twice instead. I had made a very large quantity of pots in anticipation of the wood firing (over 6 cubic feet of work), but in the end, I probably got 1/3rd of that volume fired. Still, not a bad haul. These are a few of the pots that came out of the first load. To get these very matte blacks and smoky greys, the kiln was reduction cooled to develop more depth of surface etc. I'll have more pictures when I get around to shooting them.

Fun With Sodium Vapor and Other Fiery Tales

I was recently down in Medicine Hat for a 10 day atmospheric firing workshop with Robin Dupont. The goal of the workshop was to fire the salt, the soda and the wood kiln in those 10 days as well as make enough work (on top of what we initially brought with us) to fill them. I left Calgary at about 2:30 pm after picking up one last box of clay. The trip was fairly uneventful, except for the dramatic prairie storm that was on the horizon. I was driving straight towards this huge, towering wall of storm cloud for about an hour and a half before I actually caught up to it, and then the highway veered off to the south and I essentially skirted the storm for most of the way, although I did get a bit wet. This shot is an attempt to capture the electric yellow canola fields against the stormy black backdrop.

The workshop began on Friday and we were decorating and glazing pots right away to fill the salt kiln.

Robin loading the salt kiln

While the salt kiln was firing/cooling, we were all in the studio madly making more pots. That being said, I did take time out to just relax. I was outside the kiln pad when I saw this little guy. Not your regular hare, more a peter cotton tail bunny. It was quite young and there were a whole bunch of them all over the place, hanging out in the tomato patch, under piles of scrap wood, etc.

After some debate as to schedule and when to fire, we began loading the wood kiln. We were pushed off schedule a bit because of a massive thunderstorm that knocked out the Blauww gas kiln that was full of our pots getting bisque fired, but a quick reset the next morning to finish the bisque had us back on track pretty quickly. We ended up having so much work that we ended up loading the salt again too. This shot is of the throat arch chamber that is a "secret" chamber in between the firebox and the main chamber. The pots here will get a ton of heat and ash, so fingers crossed they come out ok.

This is the main chamber and the pots here will get less ash deposited on them.

This isn't the actual storm, but it was a precursor to the one that knocked the gas kiln out.

Once the wood kiln was loaded, we fired it up at around 10 pm on Wednesday night. I was on stoking shift from midnight to 6am Thursday morning. This was a fairly easy shift, just keeping the fire going and spreading the coal bed around, making sure not to chuck wood into the pots that were about 2 feet away from the action.

After that shift I went to bed for about 4 hours and came back to the studio to finish glazing pots for the soda and salt kilns and to start the loading process. Somewhere around 10pm it became apparent that there was a problem. We couldn't get anyone to do the midnight to 6am shift on Thursday night/Friday morning, but even though I had really only had 4 hours of sleep in the last 24 hours, I volunteered. That was actually fun. I was on shift with Michelle, a potter from Ft. McMurray. She chopped and split wood and I stoked. We were firing with cotton wood, not the easiest wood to fire with as it is a horrible wood to chop and it burns so fast you are constantly stuffing the firebox full of logs. I did get a really good feel for how that kiln fires. I was even able to tell by the sound it was making as to when temperature would start to climb, when it needed wood, when to fill the firebox etc. The heat was insane, and I lost about a gallon of sweat. When we were nearing our goal temperature, we began spraying in about 2 lbs of soda into the main chamber.

I missed most of that morning and afternoon as I was sleeping, but I came back around 3 to witness the addition of the salt and soda. We were really concerned that the draw rings were not showing much glaze and so in an attempt to get a better read on what was going on, Robin decided to take a little cup off the bag wall that was able to fit through the port. I think we ended up adding another 3 or 4 lbs to the kiln. After we reached temp and we shut it off, Robin then perfomed a very slow cool down at around 1800F by keeping one burner on low to prevent the kiln from dropping in temperature too fast until it got to about 1400F (I'm working from memory here, so I might be off on my temps)

These are a few results from the kilns: Wood fired porcelain flask

Wood fired stoneware pitcher fired in the secret chamber. It looks really crusty, and it is, but I have cleaned and scrubbed most of the crud off of it. I still need to grind a few chunky rough spots off and smooth the handle, but it should be pretty good.

One of my favs. This cup came out of the soda kiln and is a really good example of what the slow cooling at the end achieved. It matted the surface and promoted crystal growth. In the sunlight, this surface is so amazing. There are rainbows of colour and the surface feels soft and silky. I had a few good pots out of the first salt, but only 2 cups made it into the 2nd salt and I guess I did not take any good pics of those pots, so we'll wait until I clean them up and get them ready to take to market.

My drive back home:

Early Birthday Present To Me

I ordered this a while ago and it arrived at Ceramics Canada yesterday. It is a gas conversion kit that will turn a 10cu.ft electric kiln body into a propane fired kiln with the goal of firing it in either a soda or salt atmosphere. I'm guessing soda will be the end choice as salt pretty much melts soft fire brick, but I might opt to prepare the bricks with a refractory coating like ITC 100 and that should effectively prevent salt eating away the bricks.

Running out of time

It's been a while since my last post, so here is a quick update. As you can see from the picture above, I have some "new to me" modular display shelves. My friend Susan offered this system to me for free, as it was just gathering dust in her garage. I took her up on the offer and loaded my car with a ton of shelves and uprights. I put up this 7' section last week so that I could take pictures for a sale application. There are many more sections to this, and all of various heights, but I think this will work for application purposes. I have since installed some LED lights on the underside of a few of the shelves as well as a few clip on goose neck LED lights to illuminate the pots. I ordered that banner a while ago and I think it will work just fine with this display. Of course it will not be attached to the shelves, but hung in front of the table at the sale (assuming I am accepted that is). My next task is to take good quality pictures of a few pots, but first I needed to find a battery charger for my camera battery. The original charger was lost in the flood and I have since tried a couple of times to find one that will replace it, but apparently it is not so easy to find an actual Nikon charger without buying a whole new camera. I purchased a universal charger a while ago but it failed after a while, as did the replacement I got. Now I have a different one that seems to be doing the job. We'll see how long it lasts. I also had to re fire a glaze load as it was seriously under fired when an element died mid fire. There were a lot of good pots in there, so I am hoping that everything works out and doesn't just get worse. I will need these for the picture taking mentioned above. I borrowed a photo cube from a friend of mine a little while ago and I have finally gotten around to testing it out. I was only using my iphone for these shots and the lighting was less than optimal, but still OK results. 

Looks like my weekend will be filled with working, potting, making a family dinner (that's my fault, I offered), more potting and hopefully getting some more pictures taken. I need to get that application off before the end of the month. I just looked at the calendar and YIKES, May is only 2 weeks away.

Catching up in the studio

On top of what has been going on at my condo, I have been busily beavering away in the studio. Here is a quick rundown of some of what has been going on since my last glazing frenzy

here are some of the pots from that last glaze marathon

 

This is a cup and saucer for a potential project, possibly more to follow on that, we'll see.

 

Because I never make coffee pots, I thought I would change that

 

Must have teapots 

 

More scratching as always

 

White on white scratching, front and back

That's it for now.

Glazed and loaded

This past weekend was a long weekend and I managed to get pretty much everything from the last bisque load into 2 kilns. I spent a bit more time on the glazing than I normally do, and it took me from Friday to Sunday to get it all done. I cleaned pots and waxed feet on Friday night. Saturday was spent glazing the interiors of mugs and bowls and then waxing those interiors so I could glaze the outsides without making a huge mess of the whole pot. I then finished spraying and dipping the outsides of everything and began loading. As I knew it was going to take more than 1 kiln, I tried to get an even distribution of small vs large pots in both kilns. It worked. The first kiln fired off without a hitch and was cooling all day yesterday. The 2nd kiln began firing around 2:00 on Monday and will hopefully be cool enough to have a peek at tonight. These pictures represent the "controlled chaos" of my glazing methods. The swearing was minimal, but I did take a few ibuprofen's when it was all done. My hip cant take that much standing on concrete.

In even more exciting to me and probably boring to you news, apparently the engineered hardwood was being installed on the weekend in my condo. Next come the kitchen cabinets I guess and then I might be able to move in. Waiting for an updated timeline on that. so it was a good weekend. We'll see how Shrodinger's cat (aka the pots in the kilns) did when I get to the studio tonight.

Loaded to the gills

Busy doesn't even begin to describe the studio last night. I got there at 5:20 pm and immediately began unloading my shelves of all of the green ware that I have been stockpiling over the last couple of months in order to begin loading up a bisque kiln. The first picture shows everything that I had, but there were a few pieces that did not make it in. Not to worry, there will be another bisque in about a month. The rest of the images show the bottom, middle and top layers. As you can see, it is loaded really tight. This kiln will fire off tonight and will be ready for me to begin the glaze prep on Friday. If I can get my hands on a couple of large buckets, I will also mix up the new Plainsman clear base that is so nice on the Polar Ice. I will also mix up some smaller buckets of the same clear base but will tint each with violet, pansy purple, tangerine and yellow Mason stains. Fingers are crossed that nothing cracks.

When in doubt, make mugs

Since you can never have too many mugs, I tend to always fall back on them when I just can't decide what to do next.

I got these handles attached on Friday night and now I am just waiting for them to dry out completely before I slather them in terra sigillata for another round of carpel tunnel inducing sgrafitto. I really need to get a bisque load fired, but my plans were thwarted when all the student work beat me to it and now I will have to wait until this Friday to fire. Perhaps that was for the best. It is a long weekend coming, so I can spend more time with glazing instead of rushing it, like I usually do.

A weekends worth of work and other stuff

I was at the studio on Friday night for 4 hours or so. I trimmed and attached handles to a bunch of serving/baking dishes as well as carved this somewhat creepy looking "man in the moon" platter.

I took the day off on Saturday, but was back in the studio on Sunday for 8 hours where I threw 15 mugs and then spent the day carving bowls and plates
 

Here is a plate and a bowl before, during and after carving

Production progress and plastic chasing

Setting goals does seem to work. I spent the weekend in the studio ( I managed a solid 12 hours) and was able to trim and throw way more than I normally would. I have a list of items that I will need to have for next fall which has helped me immensely. I know what I need to make now. In the past, I would walk into the studio and would not get down to business right away as I did not know what I wanted to make, or should make. This solves that problem. Now I just need to decide which items to make that are on the list. I managed to bang out some shallow baking/serving dishes. At first I was going to make them a bit square, but thought they looked contrived, so I stuck with the round ones and altered the rims a bit. I am continuing to try to make a new butter dish form. The way I make them is to throw the lid as a closed form and measure the outer diameter, then the base is thrown and I use the measurement from the lid to determine where to place the seat that will accept the lid. The only difference with these dishes is that the area where you would put your butter is actually a 2.5" - 3" tall cylinder that the dome lid fits over. The idea is that when people use a traditional butter dome and scrape their knife off, butter gets into the lid seat and then the lid gets all buttery and it can't be placed on the counter/table without getting butter all over the place. I am hoping that this will allow people to still clean off their knife without gumming up the lid. The trick is getting the lid to fit properly. I have added a little ledge right at the base of the butter reservoir that acts as a stop for the lid. I want to glaze all but the base of the lid and it's seat and didn't want it to accidentally move when being loaded into the kiln and becoming permanently welded to the base. This little ledge will hopefully help keep the lid seated properly during the glaze firing. So far I have made 6 of these new dishes and the proof will be in the glazing.The rest of the time I was throwing bakers, salt and pepper shakers, trimming, attaching handles and generally just chasing plastic around as things were drying.
