Tips and Tricks for Stubborn Naked Raku

Recommended Posts

cstovin    2

Hi all,

Normally, my Naked Raku for the most part comes right off with a little work. Sometimes I do have to soak it a little, and there are spots that are a little more work than others, which is to be expected. I just fired a red clay laguna B-Mix wavy bowl with NAked Raku. It accidentally got fired at a little higher temp than recommended, it went to 1600 degrees. The bowl came out fine, but I can't seem to get the Naked Raku off for the life of me. It is coming off in spots just fine, and in others....can't get it to budge. Anyone have any tips or tricks for getting this stuff to come off? I have tried gently (and a little more force) scraping it with a credit card so I don't scratch my clay surface. My bowl has been soaking now in water for the last 24 hours thinking that might help loosen some of it. That has helped a little, but not much. Any ideas would be appreciated. I know I have probably contributed to this by over heating, but there has got to be a way to get this off.

Charlene,

 

The slip used for naked raku only works as long as is it is fired low enough to act more like kilnwash than regular slip. Taking it too high in temperature didn't just contribute to the problem you are having, it's the whole problem. You seem to have gone just high enough to begin to fuse the slip together -- or rather, just high enough for the glaze to fuse too far into the slip or to work its way between cracks in the slip (I'm assuming you have a glaze layer over the slip since that's the only naked raku process I know). In the future you could adjust the slip to make it more refractory (probably by upping the kaolin a bit, although it might not be that simple). You may have gotten to the point where it is better to give up on scraping that piece. Often with clay you have to know when to just learn from something like this and move on.
