another question about mason stains

I have been following the posts regarding mason staiins. One method of using them as an overglaze has intrigued me. So, I am accumulating the info and will get into using the stains soon but I have a question regarding their use. Is there information as to which stains leave a residue of some sort or have fumes that will affect other glazes in the kiln during a firing? Just wondering.

Phyllis,

This is not a direct answer but.... In our initial process we used many mason stains and I found that a few were subject to something that appears like a whitish "scum" on the surface. We found that a general and simple cure was to spray a thin "wetting" layer of clear glaze over the final piece largely eliminated this issue. Of course, this is extra work but seems to assure a more
uniform final surface, and is also a chance to modify the glaze for your target of glossy to matt.


Hope this helps,
