September 21 – 23
9:00 AM – 5:00 PM (10:00 AM – 3:00 PM on the 23rd)

This is a 3-day hands-on cone 6 electric and cone 6 reduction glaze testing workshop designed to show students how to test a base recipe and get various colors. On Friday we will be preparing test tiles with a base glaze and ten colorant variations. We will fire on Saturday in the cone 6 electric and cone 6 reduction kiln and then on Sunday, we will discuss the results when they are unloaded from the kiln.

The workshop will also be a general overview of ceramic glazes, focusing on cone 6 glazes, reduction, and oxidation. We will discuss cones, kilns, firing dynamics and principles as well as applying those principles to various firing cycles. This will lead us into some basic classifications of glazes, like ash, celadon, temmoku, etc. It will be conducted in a casual question and answer format which will drive the content of the weekend. Glazes will be discussed in a practical and easy to understand dialogue designed to help potters gain an understanding of glazes, firing, and glazing.

We will discuss how and why each type of glaze works and how you can achieve them, how to adjust your glazes and how to find new ones. We will discuss glazes from John’s new book: “The Complete Guide to Mid-Range Glazes: Glazing and Firing at cone 4 – 7” as well as his High Fire Book, but will go into more detail than the book allowed.

Materials Needed:

  1. P100 or N95 OSHA approved respirator or dust mask and a quart size zip lock bag (with your name on it) to keep it in.
  2. Journal and pen, sharpie markers,
  3. One pair of latex gloves,
  4. Braun (or some other brand) kitchen hand blender (a.k.a. immersion blender)
  5. A small scoop for measuring out materials,
  6. 10 –Solo plastic cups (16 oz. clear or blue or red party cups), and a couple of glaze brushes. Make sure the hand blender fits into the Solo cup! (there are different sizes)
  7. Triple beam scale or digital scale- ask if we have enough. We need one scale per two students and the center may have some. Call ahead and ask so you don’t buy one unnecessarily.

NOTE: TEST YOUR SCALE TO MAKE SURE IT IS ACCURATE TO 0.1 GRAMS! Many digital scales won’t measure that small of an amount. Many like to stop at 2 grams – but you will need to weigh 0.2 grams or 0.5 grams for this workshop. It is also recommended that you test your scale against another triple beam or digital scale to see if it is accurate.
