Creating Your Own Cone 6 "Colorburst" Glaze with Sintered Crushed Glaze!

Sintering is a process of heating glazes to the point that they coalesce and lose their chemical water so they are not able to dissolve in water. I sintered glaze chips and applied within a glaze and fired to cone 6 for a fun effect. Below are some of the recommendations I have for best results.
In this video, I started with dry chips of two different glazes- Coyote Really Red and Cobalt
I crushed the chips into smaller pieces and placed them on a bisque plate
I then fired the chips to cone 020 to sinter them
I mixed the sintered chips into a contrast base glaze
Whereas my glazes are fairly stable, I highly recommend trying sintered chips of various glazes- maybe celadons or other glazes that might have some interesting effects.
I didn’t apply the chips to the outside of the plate, to be on the safe side should something want to fall off onto the kiln shelf.

In this video, I am using Standard 225, a nice midrange firing tan stoneware.
I am a public high school ceramics teacher at William Mason High School in Mason, Ohio. (Mason is currently the largest high school in Ohio!) As a potter, I have been working in clay for over 30 years, and I have been teaching for over 32 years, the past 22 have been specifically teaching high school ceramics. I love what I do! I have my own studio in my home basement, where I work on my personal pottery for my Etsy site; www.etsy.com/shop/KaransPotsA...
I started my TH-cam channel a few years ago, to make videos to help my students if they are absent and miss a demo, or if they would like to explore more advanced techniques independently, especially with my semester ending “Pick A Passion” projects- see link here: • Pick A Passion Project
I have been amazed to reach such a wider audience than my own students!

lovely! I wanted to try that for a long time! Now I will add that to the top of my list!

I do something similar with dried glaze chips sprinkled into wet glaze. I don’t have the option of doing cone 020 firings, as I work in a community studio and don’t control the kilns, so I can’t sinter. But the dried chips work just as well and sprinkling them allows me to control where they go and make designs with them. I’ve gotten some really fun results!

[@KaransPotsAndGlass]

Yes! I’ve shown my kids that too- the advantage of this method is that you can put it on vertical surfaces more easily!!

I put them in a bisque fire but I make sure they are not low fire glazes.

Hey there! I am looking into this little Skutt Firebox for my wife. She makes a lot of coffee mugs and I was looking at getting one of these for her to use at home instead of going to our local kiln studio. I see it fires to cone 6. But without asking her, trying to surprise her, will this kiln bisc fire the mugs and then get hot enough to fully glaze fire it? If so how long does it take for a full cone 6 firing

[@KaransPotsAndGlass]

Yes- it can bisque and also glaze to cone 6 without issue. I don’t have my log book in front of me as it’s at school- but if I remember correctly, it’s somewhere in the neighborhood of 9 hours for a slow cone 6 firing. (I prefer slow firing when doing glazes!)

Thank you so much!!!

Do you think with would work with cone 015? I don’t have cone 020 pyrometric bars 😅

[@KaransPotsAndGlass]

I would think it would!
