How'd that happen?

 A few weeks ago I was making a glaze test on a large earthenware tile.  I grabbed 5 colors of low fire glazes and quickly painted the following test:


I thought the style and colors of the test seemed somewhat framilar but didn't think much about it.  A couple of weeks later I was using a small, shallow bowl that I mix small amounts of glaze in.  I have never really looked closely at the design in the bottom of this dish, as I'm only interested in it's utility, but when I looked at it I was amazed to see that I'd copied it when I was using it  to create the above test.  Yea, probably just a coincidence.  Is this what all of our creatings in art come down to?: simply imitating the nearest image at hand??

What do you think? 


AND, what is the style of this plastic bowl surface?? No idea where it came from, it is just one of a dozen bowls in ceramics we use to mix glazes and such in? 

Whud'up, Ceramics posting #9



ASSESSING THE QUARTER, Post # 9




Fall/ 2011 has been an interesting Quarter.  I worked with a new Porcelain (Kleiber) and a new white earthenware (JG).  Generally I constructed similar forms in both clays and worked to improve those forms.  This has been a great way to compare two clay bodies and glazes and I’m’ glad I tried both new clays at one time. 

Kleiber Porcelain:  I made around 25 pieces, including two t-pots and concentrated on glaze combinations.  I am spending more time on individual pieces and on applying glazes. 

JG Earthenware.  JG is an interesting low fire clay.  I have tried some other low fdire whites (Dusky White) but they were a little to powdery.  JG builds a lot olke a porcelain and it slakes easily, absorbs water easily, and joining edges is easy as the clay, when sliped softens wel and accepts attachments.  I like the way it fires to a very white color.  The one thing that need to be watched is making sure attachments aren’t drier than the pot.  In that case, cracking will result.



It has been interesting drinking coffee out of my earthenware cups.  It appears the handles are hotter coming out of the microwave, but cool down quickly.  Earthenware is a bit clunkier and I am not sure yet how strong it is in use.  Earthenware glazes are not as resilient but being a bit softer, may actually suffer banging around a bit better than the harder porcelain.  It is exciting to start to use bright colors that are possible with the lower firing temperatures.  Guess I’ll find out more about this interesting clay with time. 

Dakot Red: I continued to make my Jars out of Dakota red (the Shop clay).  It works well to  use the shop clay for these large pieces and it avoids waste and allows the clay to be dumped back in the shop stocks.

 

NUMBERS:  I made about the same or slightly less pieces than in previous quarters and plan to continue to reduce my total quarter putput down to around 30 pieces.  I would still like to make fewer, but better pieces.  I’m am guessing that about 60% of my pieces are marketable, about 30% are suitable for the ceramic sale and the remaining 10% are complete failures, broken, or unsuccessful. 

METHODS:  This quarter I changed my production method.  I made “runs” of from 8 to 12 pieces, focusing on them until they were leather hard, then starting another set.  This allowed me to  focus better on the finished pieces and keep track of what I am making better.  I plan to stay with this method and would like to get it down to 8 to 10 pieces per fun. 



I want to continue to explore the response of JG and Kleiber to glazes and firing techniques.  I would like to eventually be able to produce marketable pieces in JG. I want to improve my forms, complete more sculpture , and improve my T-pots for utility and understand the range of low fire stains, slips, and glazes.

National Register of Big Trees

Nominating a tree to the National Big Tree Register

This is a picture of possibly the biggest Ponderosa Pine (DBH) in Yakima County.  It is located on Meeks Table and is well known to hikers in the area.  This isn't the tree that the following article is about, I just post this picture because it gives the idea of what it's like to search for local big trees. I'm measuring this beast with my walking stick.


I want to take a break from ceramics and share a story that happened several years ago.  Around 1985 I was hiking in the William O. Douglas Wilderness, packing out the remnants of an old Elk Camp that had been abandoned.  One evening a friend wandered off into the wood to water a tree and returned with some startling information.  He told me that I should check out a tree to the north of our camp, at the edge of a nameless meadow.  He said it was “god awful big” and I might be interested, knowing that a few years earlier I had helped a friend nominate a large Mt Alder tree to the National Register of Big Trees. 

What I discovered was truly large (in circumfrance) hemlock.  I wrapped a parachute chord around the tree, tied a knot at the measurement and didn’t think much more about it as I was sure that the Nation’s largest Mt. Hemlock would truly be a specimen of unique proportions.

That winter, while cleaning out my back pack I noticed a strange knot tied in my rain fly chord and remembered the large  hemlock of the previous summer.  I stretched the chord, up to the knot, on a tape measure and noted the length (around 26 feet).  Later, I crossed path with a copy of the current Big tree register book (this is before the internet, the web, email, cell phones, microbreweries, Katy Perry, and an awareness of deadly metorites ).  Strangely, this register seemed to indicate that MY “Hindoo Mt Hemlock” truly might be a contender for the Nation’s largest specimen.  I resolved to get back in to the tree with a tape measure and satisfy my curiosity.

Here is a Jo Miles photo of a Buckskin Larch snag (read, "dead tree with the bark worn off and aged by the sun).  Dead trees aren't eligible for the National Register but this picture is so unique I just had to post it here. 



Around 1988 I returned to the tree, but had forgotten my tape measure and realiscope (for determining height) but had remembered to pack an old fashioned film-type camera.  I re-measured the tree with the same parachute chord, took a couple of pictures and again resolved to return. 

When I returned home I got a copy of the nomination form and realized that only a formal measurement and application would qualify the Hindoo tree to the register. Over the years I tried to talk friends into joining me for a return to the tree but it wasn’t until 2009 that I finally found someone willing to embark on such an ardous adventure, after-all, the hike is 9 hours one way, over a ridge into a forlorn basin, up an abandoned trail to the top of a mountain, around the mountain to a lost meadow, and then, again, locate that tree. 

In 2008 my son, Matt graduated from law school and returned home for a few months to recoup, strategize, rest, and drink my beer.  One day he stated he wanted to take a really challenging hike, not some weeney hike of no consequences, but a REAL unique, one with consequence.  I mentioned the “big tree hike’, leaving out the length of the trip while focusing on the glory of possibly becoming the nominator of the largest tree of a species in the nation, and possibly the world.  He was game.

We arrived at the trailhead early one day in late August and proceeded to hike down the MJB Trail, ford Rattlesnake Creek, climb Timberwolf Mt, skirt around the fringes of the mountain into a trail-less area, find a nameless meadow and then locate, again, that huge tree.  We had remembered the tape measure and camera but figured we could simply estimate the tree height.  What we discovered when we walked up to the tree is that a large forest fire had come within 50 yards of the tree but had burned itself out and saved the tree.

These are some of the measuring tools we used to determine diameter of the trunk and tree height. 



Measurements were followed by a night in the Wilderness, then a return to Yakima where I submitted my information to the National Register of Big trees.  In cases where we were not sure of our measurements we estimated on the low side to be fair.  Matt guessed the tree was 120 feet tall, I thought more like 100 feet, so we averaged the two guesses and submitted 80 feet in our application.  Also, not being foresters, it was questionable that the tree was a Mountain Hemlock, as the western hemlock (an inferior tree of little consequences) is somewhat similar to it and also found in the same area.  A branch and needles I carried out seemed to satisfy a friendly forester, but what do foresters know?


The Hindoo tree is hard to photograph but here is an angle.  The tree can fork but the fork must be above 4.5 feet (this fork is about 9.5 feet above the ground). I wish I could nominate a tree with a clean, straight trunk, perhaps the big Ponderosa I have yet to find will make a better picture.  Here is a close up of the tape on this beast. 




January 1 of 2009 dawned fresh to our awakening realization that our nomination was not really up to the standards that the big tree folks expect for the 2009 edition.  We needed expert help in establishing our credentials, so it was up to me to find a willing expert.  Barry Donahue, U. S. Forest Service Wilderness Ranger agreed to accompany me to the tree and vouch for my measurements if I would help him monitor some camp sites  in the area.   He was also interested in a possibly shorter route to the tree.  We departed in the late summer of 2010 on a three day hike.  The tree was re-measured with better instruments, some campsites were monitored, and we determined that the shorter route was actually a day longer.  Later in the summer I was assisted by U. S. Forest Service certified Silviculturist  Matt Dahlgreen for further certification.  Matt required knee surgery the following winter and I want to thank him at this time for sacrificying his knee, for all the pain he endured, the cost of the surgery, the time required for recovery and for remaining somewhat cheerful throughout the ordeal, as it was all for a good cause.

In June of 2011 the 2010 big tree register update was published on the American Forestry magazine web site (of that name) and Matt (Hiler) and I were listed as the nominators of a National champion.  The moment was relatively anticlimactic but none the less, from time to time, someone will now say, “you are the co-nominator of a big tree, WOW” and all the hardship and pain that all of my friends and son and I went through has come to successful fruiation.  Can I say it was truly worth all of the effort?  Probably not. 

When we were measuring the tree an old sheep herder type derelict  (bum) wandered up and pointed to the top of the tree.  We weren't sure what he was pointing at, perhaps he saw a flying saucer?  Anyway, here is the photo taken by Mike Cochran.  



End of story.

Footnote.  While there are some who might think that the National Champion of a tree species means it is also the largest in the world, and thus the universe (and beyond), it must be remembered that Mt Hemlock ranger north into Canada.  Also, to claim world champion status would require a lot of traveling in far flung countries to validate that claim, though it seems reasonable.  Frances Hare, now deceased, was a Yakima native who was interested in all things “Yakima” and most things “tree” was a champion of this nomination and without her encouragement, it might never have come to bear.  Once, when we were discussing the tree I mentioned casually that I was sure this tree was the biggest Mt. Hemlock in the country, and therefore probably the world and/or universe.  Frances heard me out and then replied in a calm voice, “well Mike, I don’t think you can really say that”… and so I have chosen to not.  


Assignment # 8, Finishing the quarter


FINISHING UP Fall 2011 Quarter: 


Shown above is my ideal cup: resulting from fired stone, in a natural setting, and with no artifice.  This cup is in the Hindoo drainage.  Photo curtsey of Matt Dahlgreen.  It would be exceedingly difficult to drink from unless you have a straw or were a "bird".  Oh yea, this cup weights several tons

Right now (in Independent Clay Study, 299) I am finishing up the quarter.  I wont’ be forming any new porcelain pieces (Kleiber) and the 10 pieces that go in the next glaze firing (November 17th) will finish off that group.

Although I may make one more JG/earthenware piece before November 18, I don’t plan to start any more of these pieces this quarter.  I will concentrate on finishing the pieces I’ve started and completing “Imari” glaze experiments on the JG.  I want to test the compatibility of black and red Iron oxide, Cobalt Oxide, and Cobalt Carbonate as stains in conjunction with the shop cone 0-6 clear over-glaze.  All 21 pieces of JB will result in some sort of a glaze experiment.  I also plan to use Rachel’s new shop stains.

As an alternative to the "Hindoo cup" here is a cup i made a few quarters ago. Doesn't match up does it.  



Glaze themes include washed stains over hand constructed forms (to enhance the textured clay).  I plan to applying clear 06 glaze over the washed stains.  I’ll how compatible 06 clear glazes are on air washed and dried stains and stains refired to 06 to stabilize them.    I want to reduce smearing of stains onto the over-glazes.   Depending on how the glaze experiments go, I may use stain combinations to get the optimum effect. I also plan to use the Duncan matt glazes I purchased last summer from Tacoma Clay art on the cup or bowl lips.  I won’t have any pictures of how this is going until I get some firing done. 

I also applied the 06 shiny over-glaze to two pieces for Raku firing.  I didn’t use any stains as the unglazed surface will be black, and the glazed surface will retain the white earthenware color. 

This cup gets a bit closer to the "Hindoo Cup", it is certainly lighter by several tons.  And that handle, what was I thinking!!!



I am also preparing for the smoke firing, November 20.  I will fire two jars in the large metal barrel and one 16” jar in a smaller metal dust bin.  I will use shredded paper for fuel.  Two of these jars have cone 06 brown inner glaze which was fired on at the bisque firing which worked well.  I should have pictures of these pieces after November 21.

Here is a "snail pitcher".  It holds about 1/2 cup of liquid.  Although it is functional, I doubt there is any context where I would find a buyer for this piece.  



DRUMS:  I had a short drum critique with David Blink this week on my latest round bottom drum.  We agreed that this is clearly the best drum I’ve constructed to date.  His ideas for this drum is to cut  another hole in the drum body.  I also want to continue to pursue the snare feature but have not found the materials I need to accomplish this needed sub-sound.  The smokers at the middle of campus smoking table inspected the drum (as usual) and “Brandon” played a while on it.  I was impressed with his drumming abilities, he must have some experience.  He didn’t offer me any money for the drum, so it seems like I have more work to do on this design.  I still haven’t gotten my “bounce drum” to David, perhaps I can get it assessed before school is out. 

Here is the drum mentioned above, for your information.  If you want more info, scroll down to the "drum" post, below. 


Well, that's post assignment #8.  I sure hope I get extra credit for it/mh.
