The Learning Kiln, Round 1

I haven’t added anything to this blog since the beginning of the term but, it is now time to once again praise a great crew of people.  The students from the first Wood Fire Class at the School of Art:  Jaiwei Dai, Julia Beasley, Kendra Wile, Kewen Qiang, Monique Chartier-Kroeker, Sara Berg, Yijia Zhang, Zach Dueck, Anastasia Waly, Alexandra Ross, and Hyoungjung Lee – in no particular order.  I would also like to thank a former student and Ceramics Club co-president (with Selena Panchoo), Donna Garafolo, and a current student in another class who came to help and really did, Keith Barber.  Of the eleven students in the class, only two had ever fired a wood kiln. The learning kiln did everything that ‘it’ was supposed to do.  If a university is about learning and problem-solving and if woodfire is about building community, teamwork and collegiality then this firing was one of the most successful I have ever been a part of.  I would be proud to fire with any of these respectful, hardworking, and tenacious individuals and I am looking forward to another firing before the end of the term with this teamIMG_0365IMG_0374IMG_0380IMG_0385IMG_0391IMG_0394IMG_0399IMG_0407IMG_0409IMG_0413 if we can procure dry logs of the right length and diameter.

While I would like to be showing you amazing pictures of lovely glazed work this morning, I can’t.  We ran out of wood at cone 3 after using up every available piece of wood and borrowing a table saw from Keith and a chainsaw from Donna.  The Oxyprobe worked brilliantly.  Students learned how to translate numbers into reducing or oxidising and even neutral atmospheres inside the kiln.  They were, however, disappointed at not having bellowing black smoke go everywhere – the kiln is, after all, a smokeless one.  They learned about building a proper ember bed and not blocking the flue, about ‘stoking on the hobs’ – even the word was like one from a totally foreign language – hobs, what are hobs?  Oh, those are the hobs!  It is interesting, as a teacher, to find that actually doing something is more of a learning tool than reading and talking about it (a bit like reading how to put a diaper on a baby and then being presented with a real child)- especially when most of the students do not know the language of wood firing.  The majority did not know what an ember was nevermind an ember bed.  They do now!

These students did everything right according to Steve Harrison’s Laid Back Wood Firing and Markus Boehm’s instructions in the summer.  They pre-heated the kiln with gas (thanks Sara from coming out in the middle of the night) and then started using sticks and branches to start the ember bed before going full fire on the floor.  They built one of the most beautiful ember beds I have seen in a long time.  They went to the hobs following the schedule in Steve Harrison’s Laidback Wood Firing – a book that I will now require for this class in the future.  But it was there with them at every moment.  And the temperature rose slowly not to warp or dunt the pieces inside.  One of the surprises to them was one that caused a moment of problem-solving.  The flames which had been ‘going down’ in the Bourry Box began to look like a ‘campfire’ – they were coming up.  When we ran out of dry suitable wood, they attempted to use some cut off slabs (remember I said they didn’t want to give up) and one of these blocked the flue into the main chamber for a bit.  Back on track they built up their ember bed, went back to the hobs, and then got to full-blown fire resulting in reduction.

Harrison lists the possibilities for a stall and we carefully examined page 14 and his list.  We ruled out not enough ember pile to preheat combustion (see feature photo with logs on hobs), going to the hobs too quickly (we followed the medium length firing schedule in the book), top of the firebox was hot enough, and we had good dry pieces when we went on the hobs (again see above).  The firebox design was made for one-metre poplar logs and worked well at the first firing.  And the students did not forget to clam up the bottom stokehole door.  This left us with two choices and they were the two culprits that defeated us at cone 3:  too big a cross-section of timber because of the large mass it took too long to reach the flashing point and that wood was wet.   We sealed up everything and cleaned up.  The area looked fantastic due to their efforts.  And, in the midst of all of this, we also did a raku firing.

So I want to repeat something because I do not want anyone to consider this firing a failure; it is not the student’s fault that the wood we had available to us at a crucial juncture was too big and too wet.  This is a learning kiln and if University is about learning and problem-solving, then this firing was 100% successful!  I do not want the students, or anyone, to think that a kiln full of beautiful glazed ceramics is ever the only goal.  If this firing had gone perfect, I actually suspect that the learning aspect would have been minimal.  We, me and the students, are humbled along with all other wood firing potters, even Steve Harrison, who have had issues firing their kilns.  I suspect that that is what, over the years, inspired Harrison to write his book so that we could learn from his experience.  Next time we are going to measure the diameter of the logs and their length.  I would give anything for the tool to measure the wetness of wood.  We will have our own chainsaw (and gas – thanks again, Donna and Keith).  We will, once again, check what to do in the ‘Harrison Bible’ and the firing will result in lovely glazed cone 12 ceramics.

Summer Students Finish Up (almost)

Five students at the University of Manitoba worked on various aspects of ceramics over the summer months.  They are winding up their studies and it is time for you to see some of the work that they completed.  They were Iris Smith, Jade Shynkaruk, Rebecca Sutherland, Sara Berg, and Selena Dyck.

These five students discovered in the spring that they required anywhere from 3-9 credit hours at the 3000 level in order to enter their Honours or 4th year of study.  Of the five, three work almost full time.  One student, Jade, had more experience with clay and is the President of the Ceramics Club for 2018-19.  One student, Rebecca, had no experience with clay.  The other three:  Iris, Sara, and Selena, had taken the three credit hour beginning wheel throwing class in the fall of 2017 and another course in wheel throwing in the winter.  At the School of Art, students take five three-credit hour classes per term.  In other words, these students did not have the luxury of working full time in the ceramics space until this summer.  Each was working on a different project.

Sara Berg is very interested in Classical Chinese cobalt painting on porcelain.  She wanted to master, as best she could, this technique before moving on to her own subject matter that would still be expressed in this ancient technique.  She also worked on classical forms and took part in the wood kiln workshop where she not only learned to properly mortar bricks and the laying of bricks but also was able to use her welding skills to create the frame for the kiln.  We were really grateful for these hidden talents!  Little did we know that she was also a diesel mechanic and had a license to drive an 18 wheeler.  Sara moved to painting her own story on the largest of the porcelain stools she constructed – a young warrior woman and she is truly a warrior!  She has not had the time to study the history of ceramics and the inspiring women of the 20th century but she came up with one bowl that is so reminiscent of Lucie Rie that I am including it.  Can’t wait to see what she does this fall.  DSC02959

Selena Dyck wanted to study cone 6 glazes.  She loves blue and green.  Selena’s work exhibits a dedication to detail, mastery of form, and consistent testing and questioning.  Her first project was to make a 12 piece place setting of dishes.  Her second was to create 40 test pots and learn how to take a transparent glaze, make it opaque, and then colour both the transparent and the opaque base.  She discovered that she prefers the cone 6 Campana clear with copper carbonate added.  Selena challenged herself to create a set of 5 perfect nesting bowls – which she certainly accomplished!  Her dedication to keeping her glaze journal, the details about each of the glazes and their reaction and where they were in the kiln will be a good tool for her in the future.  Selena was the first one to discover that Reitz Water Blue pinholes.  We now think that the overfilling of our kilns is the cause.  Didn’t impact the smaller bowls but was readily apparent on the larger ones.  Selena asked all of the right questions – has an enquiring and observational mind.  She would make a great ceramist.  The handles on the cups at the front fooled our MFA student.  Mary thought they were press-moulded.  Nope.  Selena got very good at pulling handles!  Sadly, the ceramics area is losing her to print media in year 4.

Jade Shynkaruk came to Winnipeg from Brandon where she had studied ceramics.  She has a keen eye for a colour palette, understands the importance of colours and how they relate to interiors, and was one of the first students to know what the company Pantone does!  Jade works full time as a consultant at one of the Benjamin-Moore stores in Winnipeg and she translates that work into her ceramics which sell off the tables whenever there is a Club sale.  I am super impressed with the weight of her work, the size of the coffee cups, and the care that she takes figuring out the glazing and how the colours relate to one another.  Jade is not ready to set out and become a full time production potter but she worked on all the things that a professional potter had to master:  form, repetition of form, the right weight for the vessel, and the glazing.  She will do very well.  She also has an Etsy site:  Etsy.com/shop/jadecoraldesignDSC02923

 

Rebecca Sutherland came and wanted to try and see if she could take her love for Japanese ceramics and translate that into a short course in clay.  Rebecca had never worked with clay at the beginning of June.  And I have to admit that there was a part of me that worried an awful lot about her.  So, never touched clay before June and works full time at a Canadian bank.  This is an independent study class.  We met over the summer but, until today, I had never seen any of her work glazed.  Rebecca was marked on her progress during the course.  From nothing to a beautiful bento box out of clay with a pressed bamboo motif.  It displayed an attention to detail and the colour that she choose worked well, pooling darker in the blades of the Asian grass.  I am hoping that she keeps working.

Iris likes colour (and marbles melted onto her plates).  When I first met her, I said something about orange, possibly that it was not so popular a colour in ceramics, unlike blue which I was told once, ‘everybody loves’.  Iris chirped up and said, ‘I like orange’.  She also likes green, pink, and takes a lot of risks in terms of putting colour together.  Iris took other academic courses while working almost full time and also finding time to train new staff at Starbuck’s.  I want to add here that she gave me a new respect for the coffee chain because they provide benefits for their part time staff.  Tomorrow she goes back to being full time before classes resume in September.  Iris approaches her work as something she wants to use.  Because she has arthritis in her fingers, she presses in the sides of her tumblers so that she can grasp them easily and on her rice bowls she faceted the sides.  Look at the combination of the Reitz water blue on the interior of the pink tumblers.  Quite unique.

It was my privilege to work with these five young women over the summer.  To see what a concentrated time on a single project can benefit their learning.  I wish each of the five of them the very best.  Please keep your eyes out for their work…they are the young rising ceramic stars.  This includes Selena who I hope we can lure back into clay!

Apologies for the photos.  The lack of any quality is all mine and I should add that because of the light this morning, some of the work really is much more beautiful in person.

Great firing, even greater crew!

The work coming out of the first firing of the new Bourry box kiln was fantastic.  It was just a wonderful group of people who will stay in touch.  Mike Astill has his own wood kiln in Ile des Chenes but joined us (he is a fabulous former student from the School) and entertained many of the crew while they were here from out of town.  Thanks, Mike and Maria!

The firing survived the old soda shelves that oozed soda and are so brittle they could cut someone’s arm off if broken.  We love Markus’s wadding recipe because it flakes off easily.  His glazes were amazing as were some of the ones the crew brought. There is good biidoro at the lower level which reached well beyond cone 13.  And the kiln fires like a rocket.  Might have said, we had to slow it down by soaking the poplar logs.  We will modify the bagwall, use a smaller shelf on the top and not load the pots so near the roof to even out the temperature.  Everyone was happy!  What a way to end 9 days together – not wanting to leave.

Day 7. Kiln Built and Fired in one week. Cone 12. 13 hours firing. Used ONLY half a cord of wood. What an incredible group and give it up for Markus Boehm-it truly is a smokeless kiln!!!!!!!!!!!

Believe it or not, with all the heat, the sweat, the need for a shower – when the kiln reached temperature, it was almost disbelief by those standing doing the last shifts. Amazing group of people who then dug in and cleaned up the kiln pad and who can’t wait to hear a talk by Markus tomorrow and see the results late Saturday.

Stay tuned!

Need a chimney built? Rebecca Wong from Vancouver can really swing a mallet. Helping out is Zach Quin, Smiling Cow Studio, Maple Creek Saskatchewan

It is Day 4.  The arch of the main chamber is up and cast.  Tomorrow there will be lots of welding and the chimney will go up while the lid to the firebox is cast…everything looks like it is a go for a firing on Thursday.  Fingers crossed!

If you are looking for a great kiln builder that knows the importance of using good materials so your kiln will last, the need to save the environment (less wood) and someone who can truly build a smokeless kiln, then look no further than Markus Boehm.
