In Topic: Repairing Cracked Bisque

01 July 2013 - 03:56 PM

You know, that is totally what I heard over and over from my Ceramic's Professor, don't fool with things, just do another. That being because he knew how easy it was to throw a hundred cups and he knew I was capable. I totally agree with his advise, yet, in my home studio I use paper clay or mix sodium silicate with a small amount of ball clay. (I use sodium silicate to re-attach bisque parts) In this case, it fills the gap, I glaze fire it and found that it has been successful. I stilt it for safety if it does melt through, never has. But my feeling is, it's all an experiment each time the kiln fires up. Learning by mistake only comes by trying. Good luck, try, that's the advise I prefer. It's been successful for me.

In Topic: Repairing Cracked Bisque

I just did my first bisque firing. Everything but one item came out great. one cup came out with a hairline crack in the bottom corner, from under and up the side , about a quarter inch on both edges and is all the way through to the inside. Is there a way I repair the hairline crack in bisque or it the cup a total loss?

It's probably not worth the time and effort, it would take, to attempt to repair it. It would also probably not be functional, even if you did manage to repair it. Also, the crack could worsen during the further stress of the glaze firing.
Make another to replace it, and use the current one, to experiment with a new glaze combination.
