Just a few Images of fountains, and an associated video clip.

The fountain in the picture above is about 18 inches in height. There's a pump nested in the base pedestal- flow rate is adjustable.

The top vessel fascinates me. Exactly the same glaze on both sides... but differing levels of reduction. Raku is so unpredictable!
This is an alternate design (basal bowl rather than a pedestal). I have several alternate upper pieces for this model- see images below. The design above is a brook trout. The pieces below feature a Giant Pacific Octopus and the (highly endangered) Pacific Cod.
Picture
For both fountain designs, I've integrated a planter into the rim of the base vessel. The idea is to plant some trailing foliage in the planter. If water levels are maintained, the planter will then be self watering.

I haven't installed plants in these specific pieces, but here's a fountain that we currently have in the front room of our house. The foliage is wooly thyme- an herb that seems to be pretty resilient in the face of variable water levels. Looks nice too... and you can even dust a bit on your pumpkin gnocchi  if you feel the urge.

Finally- here's some video. I recorded this on my ipod, so the sound quality's not ideal... but you get the idea.
 
 
Picture
This glaze is absolutely driving me nuts!

Part of the pleasure of firing pots using the raku process lies with the unpredictability. A raku potter can control a number of things- these include:
  • chemistry of glaze
  • thickness and application texture of glaze
  • temperature, duration and intensity of the firing process
  • level of oxygen in the firing atmosphere
  • length, timing and intensity of post-fire reduction
However, there does seem to be some fey, gremlin-like entity at play. Two pots with the apparent same conditions can come out looking like changelings from some Kafka-esque nightmare.

So- having acknowledged the vagaries of raku- I still have say that this &**@# Egyptian blue glaze is in its own league in terms of willful lack of constraint.

At its best- it yields a mixture of vibrant reds and oranges, with copper bits... and then areas of sky blue where the glaze is abraded. The two views of the vase (below) are good examples, as is the shot of the 'bowling ball with breaking wave' piece (left).

Picture
Unfortunately, it's very easy to over-reduce this glaze (as in this example). Not that I'm prejudiced against brick reds... but the ceramics world is crammed full of sweeping palettes infused with mud, rust, and other less discrete shades.

(I had a kid look at one of my pots once and yell 'that pot looks like pooooooooooo!')



Picture
It's worth noting that when this glaze 'works' (as in the two top examples) the texture is very matte, almost sandstone-like. In contrast, the example on the left was fired at a comparatively high temperature for raku (maxing out at 1900 degree). The surface evokes the rough hide of a mutated scarab beetle, and looks like algal scum on a cow pond.

OK- that's a bit harsh... but it's definitely not the effect I'd like to see with this glaze. I do like the way that the example on the right 'flashed' on the rim of the carved mountain design (very sunset-like).

I've never been systematic enough with this glaze... but I have a few theories...
  1. I think that the 'weathered sandstone' texture stems from a lower firing temperature...
  2. I think that the complex color scheme stems from a fast, oxidized firing followed by a strong post-fire reduction
  3. I also theorized that the 'layered' appearance was linked to a thicker application of the glaze
The voucher pieces at the top of the page were both fired on a glorious summer day. High pressure system parked over Moscow, Idaho, and not a twitch from the west wind. The kiln raced to 1800 degrees. The pieces were reduced intensely (all the paper was consumed in the trash can) but not for very long.

Picture
With this in mind, I tried to mimic these conditions at my last firing. Unfortunately, I tried to pull too early, and the glaze on the interior hadn't fully matured. I had to close the kiln, bring it back up to temperature. As a consequence, the glaze probably was subjected to a lot more heat work than I intended.

The first piece out was a classic 'algae delux' model... but not too unattractive. It also has more of the glassy texture than I wanted. Still- not unattractive.

The second, which was pulled sooner and reduced more intensely, had the same surface texture, but more of the blue highlights that I'm looking for (but without the reds and oranges). See below.



Anyhow, no definitive answers- rather, plenty to work on. Story of my life!

Here's the recipe, if you're interested in telling me what I'm doing wrong.

I'm placing some wares with a Seattle-area gallery. Thus, the past couple of weeks have been a bit of a crank session.

Our house isn't exactly swarming with free storage space. At the moment, I've got a whole pile of pots under the kitchen table. Our Slovenian visiting scientist friend Maja almost juggled a couple of these around midnight the other night. With her feet. I can be pathetically blase about the things that I make.



Picture
The gallery is interested in displaying a range of my fountains... which is gratifying, as I've poured a healthy dollop of creative energy into the things. I already posted about the design on the right- (one image of a prototype on display in our house, the other an example from my raku run yesterday.

For a multi-angle view of the upper vessel, see below.

Picture
Here's a newer design. The base vessel is chalice-shaped, and holds the pump. The doughnut-shaped component is intended to function as a planter- while the upper vessel rests on a sculptural element with integrated wave shapes.

Definitely a few notches in complexity above your average bowl or mug... but that's a big part of the fun.

I haven't shot any video yet- but this one functions beautifully. See the page header for a full view.

Picture
Here's a similar design, but with the base vessel modeled on a basin rather than a chalice. Again- lovely functionality. You could conceivably stuff a couple of goldfish or betas into the vessel. I believe that they're both nimble enough to avoid getting sucked into the intake- wouldn't want them to suffer the fate of the dude on the far right.

(That's an obscure Firefly reference for the geeks among us).

Picture
I've also been grinding out a run of planters.

I've decided to stop making overflow trays for my planters using raky techniques. Not only does raku tend to be porous, but it all too frequently cracks in the fire. We've already suffered a couple counter-top blowouts.

The more I think about it, the more I believe that a neutral basal piece really suits a raku planter best- sort of a tabla rasa against which the planter itself can pop out.

But... let the viewer decide!


 
 
All hail the ceramic snowmonkey!! This is not what I had in mind when I started work on a new fountain the other day.
Picture
There’s no creative endeavor that truly succeeds without a certain reckless abandon. I’ve probably experienced this type of insomniescent, manic energy more with pottery than with any other act of genesis… this includes song-writing, dabbling in fiction, essaying… and even science.

There are an almost limitless array of plans for fountains in my head at the moment. Fountains that support fish. Fountains with trailing wildflowers. Raku fountains. Massive, honking garden-sized fountains.

The problem is that reckless abandon is a chancy guide when you’re crafting a compound object that weighs in the neighborhood of 100 pounds.


Picture
I’ve had a vision for a slightly asymmetrical, cascading design kicking about in my head for some time. Several early models failed because of mechanical flaws… or because the design was too fragile, and collapsed when I tried to move it into the kiln.

I think I’ve worked out most of the mechanical issues. Having a large basal catchment is key… I’ve also started using slabs as supporting trusses within the structure.

So- thinking that I was now primed to receive libations as the fountain god, I spent a morning bashing out the following components on the wheel…

-       Basal pedestal
-       Catch basin
-       Slab (for structural, supporting elements)
-       Two globes as water basins
-       Two smaller globes, nested inside the larger, for water-loving, trailing plants

Picture
Bit of a ramified process (which is part of the fun)

However, I was less Entish than I should have been (treebeard fans will follow the reference). 

Thus, the final assemblage came out A) more symmetrical than I wanted, and B) a bit top-heavy.


Picture
I really want a certain organic integrity in these fountains. Slate-carven riverbeds and urchin-etched tidepools are what I’m after. Frosty the snow-fountain misses the mark, I fear.

On the plus side, I think that this model should function beautifully. I’m hoping to plant watercress in the planters- maybe a few wayward plants will soften the aspect. A coating of glaze will probably help too.

Or… I could just plant a dwarf spruce or two and embrace my inner Burl Ives.

Anyhow, my resolution for future fountains is to never build without a detailed sketch. In many cases, in fact, I think I’m going to build maquettes (scale models… see the special features on the Lord of Rings DVDs for more information than you’ll ever be able to process).

Spontaneity is all well… but I think I’ll leave my extemporaneous work to objects of ten pound and under from now on.

Bit of an epic Raku session yesterday! Hard to beat the volcanic throb of a hot kiln under Idaho skies in spring.

As I've lightly alluded to in the past, I'm working on a project based off Douglas Adams' 'Last Chance to See'  a series of musical instruments with endangered species motifs. The first iteration involves a replication of a Maori gourd instrument called a Hue Puruhau. I shared some early designs and images of wheel work in a couple of earlier entries.

Picture
Here's the first version. This piece was fired a couple of weeks ago. As you can see, I modified the early bottle shape, shortening the neck, and altering the surface (with a blunt piece of wood) to make it look more 'gourd-like'.

I'm not 100% thrilled with this effort. I think that the design is out of proportion to the piece. Also- it's supposed to be a musical instrument, played like a bottle or flute, and I can't get a tone out that out-sweetens the moan of a prion-riddled cow. I can't claim to be an expert on flute making, but I know something about embouchure from my dabblings in Irish music, and this thing doesn't have it.

Here's design number two, hot out of the kiln as of 8:45 last night...

Picture
I like this one a lot more.

Apart from the tasty crackle pattern (good crackle makes Raku artists salivate) I think that the piece is more proportionally balanced. It also plays. A Hue Puruhau is supposed to yield a low, almost conch-like note- a sound that could sooth the angry seas.

I might have to test this one on the local Arboretum pond first, but at least it's functional.

Anyhow, I'm curious as to what people think- just visually- about the two pieces

(And... I defy any of you- at the very least if you're not Maori- to take a self-portrait blowing on a Hue Puruhau without looking like a complete ding-dong).

In addition to kakapo gourds, I also fired a couple drum bases and planters. Here are some images...
Picture
I've learned a couple important lessons about Raku over the past year.

For one- the clays sold as 'Raku clays' (all of which feature added grit 'for strength') are  very frustrating to carve. My carving tool tends to grab as it moves over the clay, catching on the grog. You get jerky, irregular lines... and representational forms are particularly hard to transcribe.

This is all a roundabout way to say that the nymph on this planter looked a LOT better in my sketchbook.

I should not that I don't blithely put random naked gals on my stuff- there's a whole mythology-based story behind this design. Yup. Sure.

Picture
I mentioned in an earlier post that I've been riffing off a beautiful illustrated book called '365 fish' (imaginative title, that).

This fellow is known- in polite company- as a 'Bombay Duck'. Harpadon nehereus- # 139 on this list. Glows in the dark, and is consumed with great relish on the streets of Maharashtra, India.

Picture
I culled a few ideas from the same book in designing these drums. Eventually (after I get back from Ecuador in June) I'll slap a drum head on these guys and post a few pictures.

On the right, we have the noble Zeus faber, also known as a 'John Dory'. These are spurned by fishermen because of the massive head and gratuitous spines, but Catholics honor them as 'Saint Peter's Fish'. There's a golden, coin-like marking on the flank of the fish... apparently, Peter, pulled this coin from the fish's mouth.

One the left, we have the equally amazing Regalecus glense- literally translates out as 'King of Herrings'. Number 178. Specimens have been captured that exceeded 11 meters in length (they're registered with Guinness as the 'world's longest fish').

It's hypothesized that legends of sea serpents may have originated with sightings of R. glenseWhile I defy such unimaginative thinking (I want my Kracken, dang it) I have to admit that that's a pretty snaky-looking fish...


Picture
Finally, one of the lovely things about Raku is the social aspect. There's something very joyful about sharing a bout of pyromaniac bliss with a group of friends. I always feel like I've been cast back to the dawn of Stonehenge.

Celeste (pictured at left) was a student in my fall Conservation Biology class, and a fine sculptor. She's got a particular affinity for wild ungulates- note the pronghorn in the photo, pre-fire.

Anyhow, Celeste came over with her friend Carrie, and ran three animal busts through my kiln.

I was a bit worried- these were fairly delicate little creations, and sculpture often lacks the resistance to thermal shock that you can get with wheel-thrown pottery. Also, Celeste wasn't familiar with my glazes, and had to slap some stuff on at the eleventh hour.

Picture
This was the first piece we fired. Celeste says that it was a gemsbok. I have to believe her, since she's WAY more representational in her work than I am. (Plus, she's a full-fledged biology graduate as of this week).

The piece was formed from a high-iron red clay. I've never used that type of clay in Raku, and had NO idea as to which of my glazes would work. In the end, she went with a turquoise crackle that I bogarted from Jeff Guin and his groovy 'Clean Mud' blog.

I've got to say- the glaze came out looking stunning- both the texture and appearance of a mid-life bronze patina. I may have to Raku fire high-iron clay more often.

Picture
The pronghorn also turned out- not only interesting- but also beautiful.

Anyhow, I'm taking eight students to Ecuador on Monday- starting in on several months of research in the High Andes, so I'm about to go through force wheel withdrawal. Oh well. If there's anything on the same level of fun as Raku, it's chasing mountain tapirs in the Páramo.

Hasta luego!
