Glaze Tests – Early Summer 2012

Finally…

I finally have some glaze test results from early summer. I decided if I was going to share them I may as well go all out and make them useful for anyone else that might be testing ^6 glazes in oxidation. If you click one of the six images below you should see the full-size, more readable images.

All base glazes are from the fabulous book: Mastering Cone 6 Glazes (affiliate link).

High Calcium Semimatte Base 2

I’m interested in developing some semi-matte glazes to add a little surface variety to my work. Here are two groups of test tiles with the High Calcium Semimatte 2 from Mastering Cone 6 Glazes (pg. 89).

I was really impressed with these two groups of glazes. I plan to use at least a few of these in the future after some more testing. I have already tested this base glaze with some more colorant combinations. It should be noted that the first tile in the bottom image is the “Bone” glaze from the book and the third tile is “Raw Sienna” both mentioned on page 90.

Licorice Variations (Glossy Base 2)

A few variations on the Licorice glaze presented on page 97.

The book says that Licorice is about as trouble free as a glaze gets so I plan to use it in the future. There wasn’t much variation in this test group except for translucent to opaque.

Glossy Base Glaze 1

Varying amounts of Red Iron Oxide and Rutile with the base glaze on page 92.

Not a lot here that I’m really impressed with. Some of the browns in the top group are okay

Waterfall Brown

This is the one you came to see. A few variations on this specialty glaze on page 107.

These are the test tiles that I could spend all day looking at. There is such a great range of color in every tile and an unexpected difference from tile to tile. A couple of the tiles have a few pinholes or blisters but I’ll have to do more testing to see if it’s just poor application or a problem with the ingredients or what.

Thanks for looking! I have another round of tiles already fired but I still have to photograph them.
