Silver Lining Made of Mucus

I woke up on Tuesday of this week with a painful sore throat, but decided to just power though - no sick time for classes, and I sure as shit can't afford to not get paid. So, give me some throat lozenges and I'm off! That actually went okay most of the day - you know how sometimes you feel better once you get moving - but around 8:30 pm I hit a wall, and ended up bagging out a few minutes early. My students cleaned my wheel, bless their hearts.

I spent the day in bed Wednesday, though I could ill afford that, either, with holiday events coming up, but sometimes your body just says, "Tough shit. You're down, and you're staying down. Get used to it." Thursday was better and I again scraped myself together enough to get to class. There was that little matter of the delay caused by a plane landing on the interstate, but wevs, it was fine.

I swear there's a point to this recitation. Oh, and here it is!

On Friday, still sick but a little better, and unwilling to give up another working day, I spent the day in bed compiling the Glaze Notebook! You remember: the popular reward for Kickstarter backers, that was due in September? Yeah.

Like so many things, it seemed daunting before I started. Most of the testing and revising work is done, so really it was just assembling the best recipes and typing up notes on firing. And like so many things, it's fun once you get started. I want to thank my backers for their patience, and I hope it's worth the wait. I expect to have PDFs out by the end of the month [edit: turned out to be by the end of the day! :)], and hard copies going out shortly after that. Once those are all completed, the Fine Mess Glaze Notebook will be available for general purchase.

Thanks again.

Thursday Inspiration: Marion Peters Angelica

Last spring I renewed my intermittent subscription to Pottery Making Illustrated. I like the magazine, as well as its older cousin Ceramics Monthly, but magazine subscriptions are not always in the budget. I chose PMI over CM because I am often looking for ideas for class demos; some of my students have taken my classes many times over, and I like to be able to show them something new once in a while.

November's issue features a how-to for slab-built champagnes flutes which are clever and elegant, but easy enough for beginners to do. I demonstrated these for my classes last week, and saw some delightful pieces come out of those sessions.

The author of the article, Marion Peters Angelica, makes tons of amazing slab-built things, in addition to the champagne flutes that were the focus of the article. Lookie here:

This One's For You...

...Liz Proffetty, of Liz Proffetty Ceramics! I am sending out this, the last of the Kickstarter mugs today, as well as two last teabowls, to some very patient backers. This mug is going to my potter buddy Liz because I think she will love the delicate colors.

The glaze recipe book is almost done as well, needing only a good ^6 version of Shino Sauce. It's still on my list to write a post about the last firing, in particular the test glazes. It ain't happening today but I might get to it tomorrow!

Psssst!

Anybody wanna buy pots?

The light was perfect for my living room to become my ad hoc photography studio, so I shot some pics and posted new items on my website this afternoon. It was a brilliant sunny day, very warm for mid-Ocotber, and I can think of ways I would rather have spent it than all the fiddly tapping and clicking that is website work, but I keep remi
nding myself that if I had a straight job, I'd go to work rain or shine, no matter how shiny. Discipline!

Here are the new items. Click the photos to see more:

Pop quiz: can you tell which of these items are ^6, and which ^10? Oh, speaking of: several of the ^6 glaze tests came very nice out of the recent firing, including Tenmoku, Amber Celadon, and Magic White. Soda Cobalt was a little puny, and my ^6 version of Shino Sauce was...well, it was different, as they say in Minnesota. I've lost my light, so photos will have to wait until tomorrow. (Aside: is it weird that Blogger does not recognize the word celadon? Tenmuko I can understand; oribe, shino, sure. But celadon? That's just the name of a color. You'll find it in, like, the J. Crew catalog. Huh.)

Basket Jag

Do you ever go on jags, during which you are interested in making one particular form, and not much else? That was me and these narrow vase-baskets a couple of weeks ago. There are bunches of them in this kiln.

Sometimes it's colanders or berry bowls; once in  blue moon it's teapots; often, of course, it's mugs. I know I can sell all of those things, but these baskets? I feel like I will need to individually explain to shoppers how you would use them. (As a vase, I guess. I was more interested in the form than the function, truth be told.)
Also in this load: salad plates, ice cream bowls, several lidded casseroles, a big serving bowl, a teapot, and a world of mugs. And, ^6 glaze tests! Here's another I am trying out.

The original, ^10 recipe came from Keith Phillips blog, Mudstuffing Sketchbook.

Last Outdoor Glazing

Finishing up the last glazing today for a ^6 reduction soda. This will probably be the last firing for which I can glaze outside, which is a bummer: glazing is such a messy business, and my studio inside is pretty small. In the winter I have to do a minor re-arrange every time it's time to glaze. It's a bit chilly out there today, but I don't mind: I've got my hot flashes to keep me warm.

This firing will include 8 test glazes and two flashing slip variations; basically to bring a flashing slip from^10 to ^6 you can usually just add 5-8% Neph Sy to the existing recipe. Write that down! That's my pearl of wisdom for today. That, and, if you are in a hurry, a kind of boilerplate approach to dropping a glaze from ^10 to ^6 is to replace to feldspar 1-for-1 with Neph Sy, and add about 10% gerstley borate. This isn't always the best way to preserve the color or the hand of the glaze but it will get you in the neighborhood. (Always keeping in mind the proportions flux of alumina and silica, which is what I have Glazemaster to help me out with. Yes, it's working again!) Alternatively, you can add 10-15% Ferro Frit 3134, which is now my favorite frit, as it is well-balanced enough itself not to require a lot of adjustment when used in this way.

Among others, I am trying again with the Amber Celadon. Here's the recipe I am testing at ^6:

Amber Celadon test

Alberta Slip          32.2
Wollastonite         12.7
Kaolin                     7.2
Gerstley Borate      9.0
Whiting                   6.8
Silica                    12.7
Neph Sy               19.5

Add:
Yellow Ochre         7.6
Bentonite               2.0

Five Glazes and A Freeze

Gah! I finally get a couple hours to work on my glaze conversions, and  - boom! - five formulas in, the Glazemaster software just ceases to work. So aggravating! It just keeps giving me the Hourglass of Despair. I've sent an email to the folks who sold it to me; I think I may have to de-install and re-install, with a new installation code, which I have to get from them.

Anyway! Here's what I was able to do before the derp dropped:

Inspiration is Where You Find It

When I drive down to Portland to teach my classes, I always bring a bin of tools and materials for my demos. At a minimum I bring my throwing tools, and my box of stamps. Students are free to borrow the stamps; I'm not one to worry that their pots will look like mine - I'd like to think it would take more than a stamp mark to duplicate me. Students who find they like the technique often make their own corral of stamps.

On Thursday, when I left class, I forgot my box of stamps.

This is sort of a big deal, as Portland is an hour away, and Friday, Saturday, Sunday are usually my most productive studio days. This happens to be a wetwork week - if I were glazing or firing, obviously less need for stamps in those cases. (And by "less" I mean "no".) I was thinking of driving down - maybe throw a bunch of ware, and make the drive while it's drying to a leatherhard, stampable state - and then my eye fell upon my new swimdress. (And by new I mean bought-used-on-Ebay-four-months-ago. What? That's why God made washing machines!) I'm not gonna go long about the swimsuit, but I am gonna say, if you're resisting buying a swimdress because it's what old ladies wear, give in and get one already! Much better for climbing in and out of canoes.

But I digress.

It occurred to me that the pattern on the swimdress would look very nice slip trailed. In the past I have just trailed simple lines or dots, but hey: no stamps? A great opportunity to expand my slip trailing skills. Here's what I came up with:

After that I started looking around the house for other fabric inspirations. And lo! the curtains right beside my desk had potential. Here's how that pattern played out:

Obviously I didn't try for a literal copying of either pattern, just let the fabric suggest botanical shapes to make. One thing I learned: I need some smaller needles if I want to do more detailed images.

Both still need handles. They are of B-Mix 5, and will be in the next ^6 firing, which should be soon, but my working time is so unpredictable lately that I am loathe to pick a date. In it will be the remaining ^6 conversion tests, which will allow me to publish the Glaze Notebook!

Bigger Wads Make Better Bottoms

That sounds vaguely obscene, doesn't it? But no:

I've always been inclined to use small wads, because to conserve wadding, because mixing it up is sort of tedious. I see now that I have been cheating myself! When the wads are too tiny, the flame, with its load of soda vapor, can't get under the pot; so the bottoms are pale and pasty and dull. Okay, that's harsh; but using bigger wads does allow vapor glaze to be deposited on the bottom, resulting in this soft, peachy, flame pattern. It's the subtle things that make a piece sing, and a beautiful bottom is definitely a plus.

Trimming Bat

My student and friend Ginette came to class one day with a great tool: a foam-rubber trimming bat. The "grippiness" of the foam saves time wadding, and allows you to trim without risking deformed rims. I made myself one:

First I cut a piece of foam rubber into a circle the size of one of my bats. I got the foam rubber at Jo-ann Fabrics; it's the sort of thing you'd use to fill out a sofa cushion.I used Gorilla Glue but I think almost any kind would work.

The bat is the sort that has pinholes.

Using a Sharpie marker, I drew concentric circles onto the foam, to help me get pieces

centered.

And Bob's your uncle! It really was much faster than my usual method of centering and trimming.

To Do Today

Today is the last day of August, and the start of Labor Day weekend - the cultural if not the astronomical end of summer. It's been a busy summer, not always in the ways I would have chosen, but I am trying to get my time back until control. With that in mind, I'm utilizing that old favorite tool of mine: the to-do list.

I unloaded a kiln on Wednesday, which never stops being fun and exciting. Thursday was sorting, pricing, packing, and delivering pots to Monkitree, Portland Pottery, and Kennebec River Artisans.

This was a ^10 firing; I've been alternating between ^6 and ^10 all summer, as it turns out that no, I can not go the whole summer without making new inventory in order to focus on the glaze conversion project. My bad! Nevertheless I am pretty much on schedule - still owe a few pottery Rewards, as well as the glaze books (of course!) but the upcoming ^6 firing will hopefully be the last of the 'test" firings, and contain more than half "real" work.

So! to the boats:

To do today:

• Scrape and grind kiln shelves. Six of my shelves are Advancers, which are crazy-expensive but necessary, as lifting the heavy regular shelves above my shoulders at arms length just had to stop. The Advancers need minimal grinding - an obvious perk - but not none. 
• It's a throwing day: cake stands are on tap (watch for a video!) and as well as pitchers and butterdishes.
• I still have pots that need homes from the last firing, so I will be preparing pots for delivery to The Artisan's Barn, Summer Island Studios, and the Bay View Company.

Soda Firing Workshop!

In conjunction with Portland Pottery and the Watershed Center for Ceramic Arts, I will be offering a Soda Firing Workshop this fall! It's happening Saturday & Sunday, September 14th & 15th at the Watershed Center. I will bring glazes,flashing slips, brushes, and trailing bottles; you bring two clay boxes of bisqued, ^10 stoneware. (I can't guarantee it will all get in the kiln but I will do my best!) We'll spend Saturday morning glazing, then break for lunch, and load the kiln in the afternoon. Portland Pottery will provide lunch on Saturday.
On Sunday we will fire the kiln. Students will learn about glaze application, loading, firing, and and have an opportunity to spray the soda mix into the kiln! I'll also provide wadding, kiln wash, and glaze recipes to interested students.
The firing will be unloaded the following Wednesday. Students are welcome but not required to attend the unloading. If you can't be there, please make arrangements to pick up your work at Portland pottery. The cost for this two-day workshop is $125.Call Portland Pottery to register, or for more details.
