Commercial Glazes Cone 6 Tests Georgies Part 4

Welcome to the Third Friday Commercial Cone 6 glaze test post.
This is part 4 of testing some Georgies Glazes.
Part 1 is here. Part 2 is here. Part 3 is here.
This 4th part is testing the base glazes on beads instead of pendants.
This time in both a chocolate clay body and porcelain - fired Slow Glaze, Cone 5 in my L&L computerized and vented kiln.
This is where I start to put glaze colors into my production line because I'm familiar enough with them to know if they are too thick, thin, need to be fired to Cone 6 or are better in the larger or smaller kiln.
It is a good place to be...
Marsha Neal Studio glaze testing underway.
Making sure to keep beads with their labeled test tiles.
Beads added to wires, put in a specific order (to make my life easier after the firing).
Labeled test tiles are put in the order of the beads in the tray.
Organization is helpful with this many tests.
Wires are laid out onto kiln posts in order.
View of kiln after the glaze firing.
Beads are removed in order and placed with their test tiles.
This was simple at this stage because I kept them all in order.
No second guessing glazes that are very similar.
Getting test tiles ready for photographing for this post.
And here are the results of the base glazes on a small chocolate clay bead and a larger porcelain bead:

Next month will be Part 5 showing the results of the combination of layered glazes.
Want those combinations? Check out my notebook from the bottom of the first post.

As always, work smart when handling glazes.
Wear gloves, particulate dust mask & safety glasses when necessary.

So what kind of glaze tests are you working on?


  1. Interesting beads and pendants set-up for my kid's ceramics classes. Thanks for the photos.

  2. Marsha, This is a wonderful post that can be used as reference for all who are interested in a foolproof method of testing glazes. I love your organizational skills and how they play out in the testing process. Thanks so much for doing all of this thinking and pic taking for all of us.

  3. Thanks - I find that once I get all this testing out of my system - it allows my creative side to become active and then have something in mind for how to finish my new creations...

    I'm happy to share my findings with you guys in the hopes that it does help you push your limits and try new things and see what kind of results you get (and it allows the scientific side of my brain to get a fix ;)
