Hi!
Opened my first glaze firing from my Skutt Automatic 1018. Used the Cone 6 program. 2232^ Medium speed, no hold^ vented. At completion, kiln read, 2237^. However when I removed my pieces, the reds were dull? As were some of the other colors( aquamarine, celedon) except not as bad. Used Standard #1194- bright red gloss, dipped one time. Hints to problem? I have attached some pictures of the reds. Can I refire them? If so, what is the best procedure?
Kiln?
Glaze not mixed well?
Too thin?
I used highwater's Little Loafer's clay( white stoneware) and Standard 112 ( brown with specks). Both are Mid range clays.

Personally, I think they look good, but then again, I am not familiar with those glazes.

You can refire glazeware, after adding another coat. However, it takes a bit of patience, as the liquid glaze, doesn't like to stick to fired glaze nearly as much as it likes to stick to bisqueware.

In regards to why they turned out as they did, it could be that the glaze was too thin, though it could also be, that not enough was applied. Did you make test tiles in advance?

Thank you, Benzine, for your quick response and acknowledgment of my pieces!
The red is supposed to be a very deep bright red, at least it is when fired in my teacher's kiln, same clay bodies, glaze, temps, one dip, etc.
I replicated those steps in my glazing however I am also thinking the glaze was too thin or I did not allow enough time in glaze dip.

I am avoiding your question on glaze tiles;(! The answer is no, I was too excited to do my first glaze fire! ๐Ÿ˜ฑPoint taken, lesson learned:)! ๐Ÿ˜„๐Ÿ˜„
I will refire them along with test tiles of my other glazes๐Ÿ˜„๐Ÿ˜„!
Thanks again!!

I know the glaze is not what you wanted, but I like the color. If you are going to refire, I recommend picking the piece you are willing to lose and refire only that one until you see what it does.

Thank you, Diane! I will take your advice! My expectations on the color being more red and glossy have clouded my ability to see the pieces for what they are:)!! I will refire one piece and see what happens!
Thank you for the response!!

I also like the color. There may not really be any reason for the color being off to you. Different kilns different environments.

Gee, they look great to me. Any time you get a red to turn out well, bravo. You may check your kiln for different spots where these glazes are better, sometimes that happens. Try some test tiles, set them in different kiln spots on different levels see if that tells you anything. At the same time do the test tiles with different thicknesses of glaze. Overall though I think these look fine.

I like the pots too. If you want to apply more glaze to an already fired piece, put it in the microwave (or oven) and heat it up. The liquid glaze sticks much better to a warmed pot. I actually get them pretty hot, as that seems to work best.

Have fun with that kiln!

The glaze on the 112 pieces looks thin to me. Plus the color of that clay is going to affect the brightness of the color, so don't expect it to be as bright as on the white clay. The white clay pieces look good to me. I wouldn't expect a red to be much brighter than that in a cone 6 glaze.

Thank you, Bob. Maybe my kiln is firing differently from my teacher's.

Thank you, Pres. I will do different level test tiles to check my kiln as well as multiple thicknesses of glaze! Of course, test tiles are the way to go!!

Thank you all for the excellent advice and compliments of my pieces. I will refire a couple of pieces using the microwave heating and definitely will do test tiles in the future!! Thank ou all again for everything! And yes, I am going to enjoy my kiln and my adventures in clay:)!

I too think the glaze on the 112 was too thin. It was as if the glaze wouldn't absorb as well on those pieces. Thank you for responding! I appreciate the expertise of everyone!
