Tea Time II

Here are few more tea pots that just came out of kiln yesterday.
After switching from Cone 10 reduction to cone 6 oxidation firing, I came to realize that cone 6 oxidation firing is a whole new realm in the ceramic world to explore. I feel it's foolish to reproduce cone 10 glaze quality in cone 6 glazes. 

Currently I just modify found cone 6 glaze recipes; mostly added more flux or overlap two glazes to make them slightly “runny”. A clean 45 degree cut on the foot rim can prevent the glaze from running to kiln shelf.

  1. They are all lovely, but I love that creamy rust over orange street. You are right about overlapping. When I first switched to cone 6 I was afraid I'd be disappointed, but with experimentation one can achieve a lot of variety at that temperature.

  5. I was taught to put 4 to 5 test tiles in every glaze firing, and I have learned well from that!!

  6. Meredith, I fired in electric kiln with cone 6 slow glaze firng program and hold 20 minutes in the end. I didn't pay attention to what temperature it reached.
    Accoeding to Orton cones, It was cone 6 down and cone 7 slightly bend.
    If you fire in your new electric kiln, you better do a cone off set in your controller. Please see my post on Dec. 6, 2009 about the cone offset info.
    Currently, I off set my controller 35 degree lower than the actual TC reading.

    1. Hi Alex, unfortunately, I don't have the recipes. I just use what were available from a community class where I teach.

  13. What is "Mystery Blue Green"?

    It looks like a Barium or Strontium Blue, especially on the pot where it is the top glaze.

    We use an" Shuji Ikeda Blue Rust" published in "Ceramic Art: Innovative Techniques"

    http://books.google.com/books?id=VrUns81O8JYC&pg=PA31&lpg=PA31&dq=shuji+ikeda+blue+rust&source=bl&ots=WViRJZ7afl&sig=UzaKjmufZjqMhvCrYqqSbnSt6Cg&hl=en&sa=X&ei=PotWUbahJsnRiAKU14DADA&ved=0CEQQ6AEwAw#v=onepage&q=shuji%20ikeda%20blue%20rust&f=false

    In our kiln, firing Ikeda Blue Rust to ^6 with a slow-cool of 50F/hour between 1,800F and 1,500F results in either green or blue matte, depending on how thick the coat of glaze is.
