Four magical letters… possibly the best four letters of any firing process!
CPLT = COMPLETE.

Always a big sigh of relief to see that something crazy didn’t happen along the way. We’re one step closer…

The flock has flown into the kiln… ready for a bisque firing.
And let me just say, I’ll feel a LOT better when these have all successfully “survived” the bisque firing. So much safer when they are “solid” and not so fragile as when they’re just dried clay!

Always a good sign to see…
four little letters that make me VERY happy!!

Just like something out of “The Wizard Of Oz”…
a bucket of water takes down the Wicked Witch of the West!!!
Well, it didn’t take a bucket… and there wasn’t a witch…
but there was a lot of MELTING!!!

So when I was loading my bisque kiln, I was loading boards full of pieces into the kiln. Many of the boards had been stored in the kiln room for a couple weeks… to dry out… as well as to get them out of my small studio space! Some of them have been there for a couple days… some for a couple weeks.

To my surprise… when I took down a board of twelve mugs from the top shelf… and found that “something” had happened to a few of them. They looked weird, and it took some time for me to process what had occured.

Apparently, there was some sort of water dripping down onto them over time. That’s the best solution I’ve come up with. There’s a electrical pipe running along the ceiling about an inch from the corner. Which I think would lineup with the drip marks on the mugs. Yes… if you look closely… I believe this is “erosion” from repeated water drips falling on them!

It had to be happening for awhile… as you can also see drips on the wall! And the amount of “melting” is kinda crazy… I think this must have been going on for quite some time! And since it was on the top shelf and out of eye-sight… who knew?!

You can actually see where there’s an actual hole all the way RIGHT THRU the bottom of the mug!!!… drip… drip… drip… kinda like Chinese Water Torture during the War!!!

Luckily, the mugs can just be broken up and reclaimed again… IT’S JUST CLAY, right?! And I’ve learned a valuable lesson… no more greenware storage on the top shelf… at least not pushed all the way back… until we find out why water might be dripping from an electrical pipe?! Now THAT doesn’t sound good either, right?!

I’m so used to cranking out as much pottery as I can usually this time of year. You know, getting ready for all of the summer art fairs. Racing to meet deadlines. Scheduling and working towards kiln dates… work, work, work. But this whole Coronavirus thing is really screwing up my mojo! With all of the summer art fairs being cancelled one after another, it’s weird to NOT have that kind of pressure & incentive to keep busy in the studio. Plus, the fact that there is NO ONE around in the studio… there’s no excitement or “energy” there either! It’s just WEIRD.

But, I have been working in the studio… trying to keep busy… trying to maintain some sort of “normalcy” in my life. Trying to find it anywhere I can! So I finally made enough work to fill a bisque kiln. So here it is… layer-by=layer. Not my tightest packed kiln… but it did feel good loading & closing the lid!

Bisque Layer #1 – mugs, oval vases, bowls & ornaments

Bisque Layer #2 – more oval vases, bowls, square vases, berry bowls and more ornaments!

Bisque Layer #3 – sgraffito platters, platters, spoon rests, tiny bowls and a square vase!

Bisque Layer #4 – more berry bowls, mugs, bowls and couple square vases

Bisque Layer #5 – small plates for berry bowls stacked to fit.

i didn’t think I even had quite enough work to fill the kiln. Turns out that I did… as there were still a few pieces that didn’t quite fit into this load. Luckily, the top shelf worked out pretty well… loading pretty much right to the top. Not a lot of extra space there!

As I was leaving the studio today, I left this festive “bowl-full-of-fun” in the kiln room just In case someone has room in their bisque kiln. I’m guessing these might there for quite awhile… luckily, dust will burn right off!!!

When asked if I have any greenware to help fill a bisque kiln… the answer is almost always YES!!! This impromptu loading happened thanks to Mary who only had a few pieces from a workshop she taught that needed to be fired… and I’m ALWAYS willing to help!

This past weekend was my 3-Night Soda-Firing Workshop. A quick introduction to the many wonders of soda-firing. We glazed, wadded, loaded, fired, cooled, unloaded, cleaned, admired and potluck’d all in three days! A lot of work… but it all starts with an empty kiln. Perfect for TEXTURE TUESDAY!!!

I started firing the soda kiln early in the morning…
trying hard to “schedule it” so that my students would be returning in the evening at the “right time” to help add the soda mixture into the kiln. The firing was pretty smooth… everything going as planned. Cones were melting & dropping as planned. I was checking the kiln every half hour to make sure everything was good.

Unfortunately, when I went down to check on the kiln at 6:00pm…
it was OFF!!! Yes, the entire kiln was OFF!!! Shut down!!!

Of course… panic ensued. Students were arriving… asking how it was going… I was freaking out. Luckily, Fred & Levi were in the building… both skilled soda kiln firers… and they helped diagnose the problem. After at least 20 minutes of the kiln being off… plus the time it took us to diagnose & fix… Levi finally got the kiln turned back on!!! Whoo-hoo!!!

HUGE THANKS to Fred & Levy who finally got the kiln up & running again.

However, it took awhile for us to get back up to temperature… and then to get it to move even further. We were right around cone six going down when the kiln shut down. All of the workshop students were there waiting… watching… asking questions… but we all know… A WATCHED KILN NEVER FIRES! At some point, you just need to open up the air & gas and let the kiln do its own thing. FIRE!!!

So we waited… we chatted… we hung-out… we waited some more… Those who were Lillstreet students had projects they could work on while we were waiting. But Charles & Cassie were stuck doing nothing… until Jacob offered up two bowls that needed to be decorated. So he decided a little “collaboration” would be great… giving them each a bowl he made for the LILLSTREET THROWDOWN class and some black underglaze!

Finally we were up & running… temperature rising, cones going down. My students weighed-out and mixed-up the soda mixture of soda ash, soda bicarbonate, whiting & wood chips. As the kiln got up to the top temperatures, we started adding the mixture into the kiln using a long angle iron inserted through the peeps on the sides right above the side fire boxes. Safety fire gloves & respirators were added to keep everyone safe!!!

When we had finally inserted all of the soda mixture into the kiln, I let it fire for about a half hour longer so that the soda mixture could float around a bit longer to “soak” inside the kiln! They loved the flames shooting out of the kiln. A lot of reduction going on. A lot of soda flying about.

After that, I shut it down… on purpose this time! It was a VERY long day of firing with a bit of panic in the middle. My workshop participants were very understanding & helpful. All with fingers crossed that this kiln “issue” in the middle wouldn’t affect their pots in a negative way. I guess we’ll find out on Monday when we unload the kiln as a group.
