Mistakes Happen: Reglazing and Refiring a Sunflower Bowl to Fix a Thin Glaze!

This video shows how to fix an issue that many potters have at some point in their pot-making. That is having a pot come out of the kiln with less than desired results, and reglazing and refiring it until it is successful. I have a bowl where I didn’t apply enough glaze, and had to refire it. I used Mayco Stroke and Coat, (which has a huge range from lowfire to cone 6, and even some go to cone 10.) The clay body is Standard 225 Brown Stoneware, with a 2% absorption at cone 6 and 12% shrinkage.
The imagery of the sunflowers was inspired by the situation happening now in Ukraine, in support of the Ukrainans living under attack, as the world rallies around them.

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 30 years, the past 20+ 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 KZfaq channel several 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. I have been amazed to reach such a wider audience than my own students!

Full disclosure: Mayco did send me some glazes to try for my videos!

Thanks, Karan! I’m using Mayco Stroke and Coat with my students. I am trying a single firing technique for my first year because the kiln is at my house. This way I don’t have to transport as many times. It’s working well-So far❤️🎨

Awesome!!! Just be sure to give it a nice preheat when single firing!! :)

I would like to see more stroke and coat use and hear your opinion. Have been using it almost exclusively but since I am a relative newbie of 2 years, not sure what to think! Sometimes happy with results sometimes not

As a greenhorn potter I am so thrilled to find your wonderful videos Karan. Haven’t tried Coyote glazes but am very interested in trying them. This video is especially interesting Re: your glaze problem with the iron based color painted over the yellow. I have seen that before as a porcelain artist (read overglaze paints). One of the first things I learned was that yellow pigments are notorious for “eating” iron based colors (reds) and to be very careful to keep them separated in porcelain painting. I wonder if some of the pigments in pottery glazes are the same as the pigments we use in porcelain painting? Maybe try a test tile to see if that could be the problem? Thanks for the wonderful videos!

Great observations, Linda- thanks!! I will definitely be testing more to see what gives! That bowl was a very impromptu idea with no prework testing any combos! I’ve only recently started playing with iron oxide accents like that- so this was a great learning experience!

I’ve been watching all of your vids as I’ve taken a greater interest in pottery and clay. I have a question though, where or how do you make your slab sticks? I don’t like the press as it may have some inconsistencies

@KaransPotsAndGlass 2 жыл бұрын

You can actually buy hardwood slab stick sets from ceramic suppliers! Or, have someone with a table saw cut you some sticks of specific thicknesses. I also found the jumbo paint stir sticks are perfect 1/4" sticks!!!

Was wondering if you have used the coyote underglaze - if you have, what is your opinion of it. I have used most all the other brands except theirs. Thank you - a beautiful bowl.

@KaransPotsAndGlass 2 жыл бұрын

Love the Coyote underglazes! I’d say a bit more than the Amaco velvets. I find the colors go to cone 6 more dependably! I am slowly switching over my school inventory to Coyote over Amaco!

@321ReadysSetG0 2 жыл бұрын

Thank you so much for your input - I would like to switch from Amaco but wasn't completely happy with others I tried. I will definitely give coyote a try -

I just used the Coyote Underglazes for the first time, and I am in love. The Mazerine Blue is SO intense.

Thanks so much! The kiln schedule is real eye-opener! 👀. Appreciate you posting! And the really quick response too!

I had a pottery instructor tell me to paint the glazed pot with white glue so that my reglazing would stick better. Have you ever tried this? Would you recommend it?

@KaransPotsAndGlass 2 жыл бұрын

Hi Susan- I’ve heard people mention this in the past. I’ve never personally done it because I’ve never found it necessary. I’m a little hesitant to add ingredients that could potentially burn and leave a slight residue within the glaze as a potential contamination. It may work perfectly well, but I’ve just found heating to do the trick for me! 🙂
