Ups and downs of firing

Just catching up here. Didn’t I just finish talking about things that can go wrong just as one’s getting ready for a show…? Perhaps I jinxed myself.

From 2 weeks ago:

Woke up this morning ..well I didn’t actually wake up, I was still up.. I wasn’t feeling too good about how the day ahead was shaping up to be. Thanks to the mega storm system blowing in from the west yesterday (tornadoes actually touched down not 15 miles north of us), the kiln didn’t get lit until mid afternoon, much later than I had planned or anticipated.

Propane tank freezing upThis firing cycle, the multimeter I’ve been using as a pyrometer for the last 9 years finally decided to bite the dust just as the kiln temp hit around 1200 degrees Celcius and it started to stall. Great. Felt like I was firing blind. Not only that but I was running out of propane..just 7% left in the tank and it was starting to freeze up. (You can see the 1/4 to 1/2 inch thick layer of ice toward the bottom of the tank in this picture). Its at times like this I get envious of people who fire electric…

Bleary eyed, I dragged the hose around and started a water trickle on the tank to hopefully gain back some of the gas pressure I was starting to lose. Took a breather, made coffee, headed for the phone, sat down and waited for the Amerigas office to open.

Amerigas manThank goodness.. By some miracle, the gas company informed me that they could come out and bring me more propane that morning. Not too happy that the same amount of propane was going to cost $70 more than it was last year, but under the circumstances, now was not the time to quibble. I was just happy to know I’d be able to finish this firing.

Went back out to check on the kiln and cone 8 was starting to bend on both top and bottom. Phew! An hour later, I hear a familiar beeping sound of the propane truck coming down the drive. Total relief.

Porcelain Curio case with dogwood relief design in celadonYou just never know for sure what you are going to get until you unbrick that kiln door. Despite my misgivings and struggle to keep the kiln lit, the firing turned out better than I had anticipated and I actually did get some decent reduction. Here is one of the porcelain pieces you saw in my last post, now glazed in celadon and fired. I love the way this kind of glaze feels and pools, giving a carved design more depth.

Ah yes.. my pyrometer. As an aside, picked up this new multimeter at Lowe’s for $21. It measures both in both Celcius and Fahrenheit and is a good alternative to more expensive pyrometers, like Fluke, out on the market. Thermocouples are available at most pottery suppliers, but I managed to find a group lot on eBay at a really good price a few years ago. I like this one better than my last, actually, as the screen is bigger and easier to read. pyrometer2.

In the studio today

Well the conference is over, the weather is fine, and I’m finally back in the studio. Yay!

Bas Relief on porcelain

Continuing to work on carving some bas relief designs on porcelain pieces I had thrown before the weekend. Its a bit of a leap of faith.. you commit all that time carving a design and hope for the best that they come out fine in the firing and all the glazes do what they’re supposed to be doing. ..on to the bisque firing they go!

Dogwood relief

Well on Saturday, despite the greatest of intentions, I didn’t end up taking very many pictures at all, but here are just a few more shots from the conference for you, this time of the three presenters: Chris Gustin, Misty Gamble, and Christa Assad.

It takes a few days to fully digest what one has seen at any workshop or conference. Sometimes you come away just brimming with excitement, inspiration and ideas, and are just rearing to go! Other times, well,.. it just takes a bit longer.

I have a question for you now.. If you were to attend a clay conference, what would you expect/like/want to see? What would you like to take away from the experience? Any dislikes…? Please comment
