"I have tried almost every glaze mentioned and only Bates clear and G1214 was crystal clear and behaved well with underglaze and iron. Bates crazed and G1214 did not. It is time to go back to testing but the studio has shut down so I now must go at…"

"For clear I use the one they designated as a clear liner glaze on page 97. They mention that it is more transparent than base glaze 1. It uses G-200 Feldspar which I still have but I've made note of the changes for using G-200 HP. "

"We too used the Mastering Cone 6 Glaze Glossy Clear Base #1 for years.  Their #2 base with more silica can run if over-applied."

"When I want a clear that doesn't go milky I use John's and Ron's Glossy Clear Liner Glaze from Mastering Cone 6 Glazes. I've not had any issues with it and I use a slow cool program. "

"George  - Looking at the comparison with G1214W, the glaze you use: Has far less calcium, so no calcium semi-matte look with a very slow-cool; Although it has 40% more boron than G1214W, it has a lower 8.0 SiB:Al ratio - so too much…"

"I recommend this glaze. I have never seen it cloudy, yellow, or blue, (though it will sometimes trap tiny air bubbles). I use it exclusively on my slip decorated pieces, As you can see on this link, I've used it for 8 years Recipe Name:…"

"Donna - In general, glazes become yellow from Iron and blue from Boron. There's two ways for G1214W to cloud up, especially with slower cooling. It has a generous amount of Boron and Silica which can produce "Boron Clouding" which is…"

Finding the perfect clear

Has anyone worked with Tony Hansen's G1214W Clear? I had thought I had found the perfect clear for our studio when I found this glaze. It did not craze on Standard clays. It was crystal clear and it behaved well with all the underglazes used with it. Then it started turning milky. I weigh the glazes so it was not an issue of thickness or application. I worried about contamination but after several new batches for testing I convinced myself that no, it was the glaze. Some people suggested that…See More

Profile Information

What is your experience with ceramics in general. (Long answer encouraged)
Though I have worked with ceramics since early 70s it has always been the smaller part of my life which I fit in as I was able. I have mixed up glazes for studios for quite a few years. Making glazes for a studio setting is quite different than what one does for ones self. Glazes which work well for a wide range of both personal taste and ability is probably one of the more challenging aspects of the work I have done. Now that I am back to only working for myself and having the time to devote to the craft, I am looking forward to potting to my hearts content.
What is your current involvement with electric fired ceramics? (long answer encouraged)
Slowly getting back into gear. I have just now gotten to the point where I realize how little I know.
