"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 alumina.to…"

"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.
