Hello George!

I was having some difficulty reactivating my former membership profile, so I created a new one.  I also thought it would be better to use a masked email in case the site was ever hacked...all too common these days, unfortunately.  In the coming week, I'll go through my photos and re-post some images of my work.  All of it is at least several years old, but I look forward to being able to add new work at some point.

I've truly missed being away from clay, and I tried to minimize the feelings of loss by staying away--letting subscriptions and memberships slide.  But it's time to reconnect.  I won't be able to work extensively with clay for several more years, but I might be able to dabble at some point this year.  And I may well need to change the way I work to fit any lingering limitations.  But that's what we creative people are really good at--working with what we have!  Necessity is truly the mother of invention, and it can lead to some really interesting and awesome creations.  :)

I hope you and your loved ones have a safe and wonderful holiday!

Hi George:

thought perhaps you might have some thoughts and opinions. Trying to figure out somewhere to put all my clay research and articles. I thought a website might do the trick, but not sure they are big enough. Ceramics Monthly has published three of my clay chemistry articles this year: one or two more yet to come. Looks like I am a regular all of the sudden: although Dave Finklenberg has been too busy these days. Any ideas?

I have several step by step abums in my facebook page

I also have a video, showing how I used the technique to decorate tiles

If you don't have a facebook account, you can see the video in youtube

Hello George,  I used your Turquoise Matte recipe on a totem of looks fantastic.  Thank you so much.  Would like to leave a pic but don't know how to.  Thank you, Colleen O'Reilly.

Hi George ,thank you for like I m very  glad to be in this group now .Greetings from Turkey .

Profile Information

What is your experience with ceramics in general. (Long answer encouraged)
Now that I've retired from my day job, I'm hoping my work in clay will provide a little secondary income, or at a minimum, pay for itself. I studied ceramics at San Francisco State University in the early 70s, and then tried to scratch out a living as a potter for several years, and finally went on to other pursuits where I could actually earn a living. For the next 30 years I never touched any plastic clay.
In 2004 I took a 10 week class at the Greater Lansing Potters Guild in Michigan, and discovered that I still really enjoy working with clay. I have taken several more classes and slowly put together a basement studio with an electric kiln, a small slab roller, and a used electric wheel.
My early experience was in the cone 10 reduction, gas-fired arena.
I founded the cone6pots network in the Spring of 2008 to provide a rich, highly interactive, online meeting place for mid-fire potters. The first couple of years saw very slow growth of membership, but now we're adding members at about fifty a month.
What is your current involvement with electric fired ceramics? (long answer encouraged)
The switch to cone 6 oxidation has led me in a whole new direction of glaze development, and it took me the best part of a year to start getting some results that I felt were acceptable. I have tested several hundred glaze recipes off the Internet, and from the books of Michael Baily, and John Hesselberth.
Using an aftermarket programmable kiln controller has allowed me much more control of my firing cycles and improved my results immensely. My introduction to single firing in 2009 has been a great boost my creative energy by compressing the creative process and making glazing more integral with the forming process instead being divorced from the raw clay processes. Attending a Steven Hill workshop in the fall of 2009 helped refocus my work on glazes that interact in complex ways and hover on the edge between chaos and control.
All our content is viewable by the public. Why do you want to be a member, when you can already see everything as a non-member?
Great interactions with other members. An online community of friends that will spill over into the real world.
Where do you work on your ceramics projects?

How did you find this network?

Also, if there are obvious issues just by looking at a glaze recipe (like high barium, insufficient clay to suspend or harden, too much feldspar (which causes crazing), too much clay (causing crawling, peeling), hard-to-get materials,…See More

George Lewter replied to Christine Stangel's discussion Is C Harris Temoku a stable Iron Red Recipe for Cone 6
"I found a great Derek Au article on an extensive testing of the common ingredients used in saturated iron glazes. It is important to remember that he is working cone 10, where iron undergoes more state changes than maxing out at cone 6."

Penny Berglund replied to George Lewter's discussion John Britt's Snowflake Crackle - The cone 6 oxidation glazes
"I will try this next test go round. It would make sense with the large bubbles I got at times. But it still doesn't explain the pinholes prevalent on the undersides of pieces that had an even glaze surface and no bubbled lava effects."

Norm Stuart replied to George Lewter's discussion John Britt's Snowflake Crackle - The cone 6 oxidation glazes

Alaska Claycation 2017 Wrapped Up

I had intended to post frequently during the retreat, but we stayed so busy with our activities that I kept putting it off. Then suddenly, it was over. The Gallery Lodge in Kasilof, Alaska was a magnificent location for our event, and the accommodations were first class.

Arrived in Anchorage yesterday and the drive down to Kasilof was spectacular. Dot's Gallery Lodge is far better than I was expecting. We'll use the garage as our studio, but she has a new studio under construction that will be a strong community gathering point for many years. I'm so glad I met her in Fort Lauderdale two years ago. Watch this space for more as we have our Alaska clay experience. The retreat starts tomorrow.…
