Issue With Rio In Black Gloss ^6 Glaze

15 May 2014 - 08:44 AM

Hello. Hopefully someone here can help me because I am scratching my head. I use a black gloss cone 6 glaze and recently had an issue with it - it came out a strange sort of light brownish/bluish color (not unpleasing but odd and not at all the gloss black I have used and require). I recently relocated and purchased the iron oxide from a different place than usual and it was the Red variety. I normally use Spanish RIO for this recipe but didn't have any on hand so used the more expensive RIO. Even though I have never substituted it before I didn't think it would make a difference. Am I missing something here? Could that have been my issue or should I be looking at some other error?

 

Here is what I used:

 

Silica: 26

FF 3134: 26

Custer Felspar: 22

EPK: 17

Talc: 5

Whiting: 4

 

RIO: 9

Cobalt Carb: 1

 

 


Slipping and Scoring

26 June 2013 - 08:10 AM

While at a workshop a few weeks ago, the subject of slipping and scoring came up. Apparently there is a whole school of thought that says this is an unnecessary waste of time. This was complete news to me. I just tested some mugs this week that I did not slip and score. I was able to pull the handles from the pot and they did seem to have a nice bond. I haven't fired the pieces yet because they are still drying. So far, all looks good. I am still a bit skeptical but very hopeful at the same time.

Love to hear your thoughts on this.

Preventing Pattern Cracking

25 June 2013 - 11:01 AM

I just made a bunch juicers and I am trying to figure out why they all got pattern cracking on them. It is like a multiple s shape at the cone of the form. I did dry them in the sun (which I have only recently begun doing with some things). Not sure if that is the culprit. I am wondering if this is an issue with how I am making the form. Any ideas?
