Life Intervenes

I have not been blogging as much as I would like lately. I am still working on my ^6 conversion - the next test is to happen in about a week - and making pots to fill my summer orders. We've had a little life change, however, which has taken some of my time and attention.

My teenage nephew has come to live with us. He is battling a heroin addiction and needed to be out of the environment in his hometown where it was easy for him to get his drug, because the temptation was too great. Heroin is an evil thing which clouds and torments the mind even long after the physical withdrawal is done. The battle is far from over, but he is a valiant warrior. We can't fight the battle for him - we can't even help much. The best we can do is give him a safe place to fight it, and try to put obstacles between him and the drug when his considerable will flags. 

Though its unlikely that anyone he knows reads this blog, it feels like an invasion of his privacy - already necessarily limited - to say much more than that. I still have lots to say about ceramics- I have a favorite frit now, that I can't wait to tell you about, for example - and will blog as time allows. In the meantime, send good thoughts our way, prayers if you've got 'em, and maybe things be alright.

Look for Thursday...

...on Friday this week. I have a few ideas for Thursday Inspiration but just won't have time to put the post together today. Gah. I need a catch-up week.

Like A Good Neighbor

I saw this and thought immediately of my neighbor, the one who called the fire department on my firing; who now thinks I am cool and comes over to drunkenly blather at me whenever she sees me working out in the kiln yard. That's better than her hating me I guess. I learned that calling 911 seems to be a hobby of hers; she recently called to report cats fighting in the parking lot of her building, and again about another neighbor walking his dog too close to her windows and upsetting her cat.

I am trying to be compassionate, as she clearly has a problem with alcohol. It would be easier, however, if she'd stay over there.

Blue Flame

A week or so ago, I had the service guy from Suburban Propane come and clean my burners. I feel like this is something I should be able to do myself, but I'm still sort of intimidated by burners, and I wanted to watch somebody else do it first - and anyway he had to come out and check for a leak I thought I smelled while trying to fire a bisque.

I am astonished at the difference in the flame! I guess I thought it would be subtle: it's not. The flame is now almost totally blue, much quieter - I never thought of that aspect at all - and giving off far less heat outside the kiln. I never knew how much heat I was losing until I wasn't anymore. Seriously I feel like the whole Global Warming thing might be my fault! But all that energy that was going to make a bunch of noise and radiate heat into the air is now going to heat the kiln, so I am in hopes my firings will be faster and more efficient.

Here's the load before I bricked up the door. These pots are headed for Monkitree in Gardiner, the Portland Pottery Cafe, the Center for Maine Craft, and On the Main, and maybe a couple of new listings on my website.

Vivika's Strawberry

Vivika’s Strawberry (^10)
15.93 Gerstley Borate
9.63 Dolomite
2.77 Whiting
44.06 Custer Feldspar
1.84 EPK/Kaolin
27.7 Flint
3.07 Tin Oxide
1.02 Copper Carbonate

I've been looking for this glaze for a long while - years. I used to use it, then I lost it, then I found it again, then I lost it, and no amount of Google-fu would bring it back to me. Well, my student and friend Joanna Skolfield of Blarney Stone Pottery located it for me; her google-fu may be better than mine, but in my defense, it was posted only three months ago - long aftr I gave up looking. She found it at the Glazebook Tumblr, which you should check out.  

It may not be well-suited for soda but it is that rarity: a true pink in ^10 reduction - but only on white claybodies, and not all of them. I will add it to the growing list of glaze conversions to ^6, but here it is in its original form for all of you, and so that I will never lose it again.

The Stranger

I've moved my glazing operations outside for the season. A little late this year; we've had a cold, rainy spring. It's nice to be outside whenever possible, and glazing is so messy that indoor clean-up can take a bunch of time I'd rather spend doing something else.

I've had company this week while I glaze for the 6/19 firing. This little cat took up residence on our deck on Monday, and has shown no inclinations to leave since then. He was skinny but shiny and apparently healthy. (He's not so skinny now, since we've been feeding him for almost a week.) He's a little luv, a lap cat - it seems like he must have been somebody's pet.

Actually, I've caught glimpses of him around the neighborhood before, just passing through the yard, for a couple of months; which raises the question: if he has a home to go to, why doesn't he go home? My fear is that somebody just moved away and didn't take him with them. Though he has hardly left our deck, I thought I should give him a chance to go home, if indeed he has a home. So I put a collar on him, thinking that if he goes home and his people see the collar, they'll either keep him in for a while - and I won't see him - or he'll come back without the collar. That was Wednesday. He's still wearing the collar.

I've called the police and humane society, but no one has reported a missing black cat in the area. He's intact, so just feeding him and letting him roam free is not an option; we can't have him making kittens that will themselves become starving strays. Adopting him ourselves is out, also, as we already have five cats, one of whom is very old and deserves some peace. So, on Monday he'll have to go to the shelter. It's the best thing for him; they will neuter him and bring him up-to-date on shots, and test him for catly disease like feline leukemia. They will also keep him for a while in case somebody out there is missing their furbaby!

Wait, Earthenware?

Well, yes. Kind of.

Just what I needed, another claybody to keep track of. I made myself a special stamp for the ^6 test pieces, because BMix 5 looks alot like Bmix 10 - unless you fire it to ^10, and then they look substantially different! But that's another post. This post is about these earthenware jars.

Remember I said I was going to have to say goodbye to some of my accounts? I thought one of those would be an account I've had for years with a veterinarian making urns for the ashes of cats. I was sad to do it - it seemed right to me that the urns should be made by a committed cat lover like me - but as I discovered at the end of last year, my old pricing was actually costing me money; and I didn't think they would be able to support the new price points.

Time for some creative thinking. But first, a story:

A couple of years ago, my husband and I lost a pet turtle to pneumonia, but ultimately to old age. His name was Big, to differentiate him from his smaller co-turtle, Red, who has a red stripe on his face. (They don't come when you call, anyway, so the names might as well be practical!) Big was an aquatic turtle, and I couldn't bear to put him in the ground, although I know his spirit had already moved on. What I had was just a shell, so to speak. But still.  So I made a container for his remains out of clay, surrounded him with blueberries and raspberries - his favorite foods, and Doug and I brought the unfired "casket" to the river. We placed it on a passing ice floe. The current carried it away. When the warming day melted the ice, Big's remains were consigned to the river. The greenware casket would of course just dissolve.

It occurred to me that folks who have lost cats might want to do something similar. A container which would hold the cremains until the owner was ready to let go, and then just dissolve in the ground once buried, might be something people would want. It would work for me with only a tiny price increase, because I wouldn't incur firing expenses. I made this suggestion to my contact at the cat doc, who agreed.

These will be stamped and adorned with slipwork; some will be burnished with terra sigilata.

By the way, I was wrong (imagine that!) about one thing: in addition to carrying the unfired urns, they also agreed to also continue to carry the fired urns, at the steep hike I found necessary. Important learning moment: so far no one has said no to the higher prices.
