Impressions of the ASU Art Museum Ceramics Research Center and Its Sponsored Studio Tour Feb. 2017

In February I heard about a major ceramic studio tour in Phoenix AZ, and decided to make an overnight trip to visit the studios and to take in the ASU Ceramic Research Center Museum, with what is widely recognized as the best collection of ceramic art, from the 1950s through the present, in the United States. I was amazed by the variety and quality…

A journey...

A journey of a thousand blogs..., uh..., begins with a blog, though I suppose this is really more of a test drive ;).

I'm finally getting around to experimenting with glazes a bit..., moving beyond the recipes provided by my instructor.

I've been looking forward to this a long time..., anticipating it.  So naturally...

When came the time to combine the dry with the wet..., what do I do?

I invert the proportion of glaze materials to water..., so end up with 4 times…

Clay Tips for Studio Potters

Why aged clay is smoother?

 

Stoneware in particular changes characteristics over time, but all clays do to some degree. The common thought is because of bacterial growth (fungus/mold, etc. Bacterial growth is a reflection of how much organics is in the clay itself (ball clay primarily). If you are getting a lot of bacterial growth on your clay: it indicates high levels of organics: which means you need to bisq slightly higher, or with a hold to burn them off…

Sardines and Tubes

Flat fish, swimming free on a dinner table, their goggly eyes staring, their mouths half smiling, their tails flicking and their bodies tattooed became the obsession of the end of summer.  Alongside a forest of unassuming tubular forms, each slightly beckoning or retreating, pensive or impatiently looking skywards.  The colours of the sea and the sky.  The porcelain shattered in inexplicable ways.  The glazes blistered or ran or jumped over obstacles and bridged ravines at will.  The winter…

Stoneware Clay Study

After finishing my porcelain clay study, I have moved on to stoneware bodies. At this point, all I am doing is studying PSD (particle size distribution). Typically commercial stoneware bodies run between 10-20% large particle size ( mesh 30-70). I will not bore you with a photo gallery, but just the difference between 20% hawthorne 35m and 50% hawthorne bond 35m is very revealing. I have seen numerous clay recipes with 40-50% large clay particles in their recipe.…

Porcelain Clay/COE Issues

I have been testing porcelain bodies for nearly two years. Recently I purchased a 1600X lab scope to help me see what I had long suspected.

This first image was taken of the clay/glaze interface: the dark area is glaze (cobalt.) The body has a strong glassy matrix and is fully vitrified: so I had to…

How I Make Glaze Test Tiles

I must admit, I've never been terribly disciplined about my test tiles through the years.  I'm pretty good about taking careful notes; too many times I've been burned by shoddy notes.  However, I do tend to slap those careful tests on whatever's laying around.  The result is a box full of…

Adjustable Slump molds

I got a chance to try one last winter at MIY Ceramics and Glass in Hollywood, Florida, and knew I wanted one of my own. 

This is set up to make a platter or shallow bowl with a mouth 12" long by 8" wide. The depth is 1 3/8". The mold sections slide in pairs allowing you to set any…

How I Mix Bentonite / Store a Glaze That Settles

If you ever used bentonite, you know it's a bear to mix into a glaze.  It tends to clump together in solution.  It doesn't want to play well with others.  I've tried a number of things over the years to get around this.  I thought I'd share this latest method that works for me:

I first look for the dry clay in my recipe, usually EPK.  Even if it's a small percentage of my recipe, I measure this out first, and place it in a resealable plastic bucket (I bought mine in the paint…

The secret of Magnetic organization from our friend Lawrence Weathers

What I need now is a device which prevents studio members from dropping tools and valuable extruder parts in our washing tub which collects clay and heavy metals from glaze for disposal.

Going through the muck prior to disposal is always a treasure hunt.

Never Misplace a Tool Again!

Glaze Ladling Techniques

This is an interesting tutorial, of sorts, illustrating the finer points of using a glaze ladle. If nothing else, it demonstrates that something so humble can be finessed into an art form. I dig that.

thermo readings

Well this is pretty annoying... Just for laughs I compared a brand new K  thermocouple with the one in my kiln. The one in the kiln still has lots of metal fused at the junction so i figured that they would be pretty much the same.



SURPRISE! one read 34.6 mv and the other 36.4mv. So I thought i would try a third as a tie breaker... 33.9 mv.  The third one was just a wire probe rather than the beefy kiln probes. but it was a K. type

we're talking about a 300 deg F+ spread at…

'phew, glad that's done.....

So my buddy & I just finished the last of these urns.  They are for a certain building over in Fort Collins, Colorado. They ordered 10 of them total.  We ended up making 19 total when all was said and done & delivered. We had breakage issues and a few glaze issues that we had to work through. In the beginning I was helping throw sections, but in the end I just helped get the clay wedged and took the torch to the sections and then I fired them & glazed them.  Just glad it's all…

Pricing of pots

Am wondering how potters decide on the worth of their work. I only do 1 show a year and also sell on ETSY. When I look at others work their prices seem to be all over the map. Do you price high and hope to sell items or low in an effort to sell more pieces. I find beautiful vases prices in the $40 to $60 range and next to it is a tea bowl priced at $55. Finding it hard to rationalize the size of the items with their respective prices. Any thoughts?

Simon Leach

So Simon was in town last night, well, actually for a few nights but he gave a demo at our local supplier, Capital Ceramics.  It was quite interesting & it was fun to meet him.  Learned a few tricks even though I don't do much small stuff.  A good time was had by all!!!  jhp

My First Attempt at Spraying Glaze

I have been a hobby potter for about 18 years.  For 10 of those years I have been visually impaired.  Making things didn’t suffer much when I lost my good sight, but glazing became a recurring nightmare.  I tried brushing glaze and couldn’t tell how thick I was applying glaze or see brush marks in the glaze.  Dipping pots is OK, but everything looks commercial if a pot is dunked in a single glaze and I cannot tell when I’ve missed a place when I glaze.  Also, I like making big pots and it…
