In my never ending quest to find lots of colors for painting, I've been looking at products offered for china painting and ceramics.  I recently purchased some 'ceramic stains' by Mason Color but haven't yet had a chance to use/experiment with them.  I'm assuming these can be used similarly to the ceramic pigments sold by Thompson?  I've had good luck with those pigments, mixing with painting flux and a medium.  So if anyone has used these and can offer some tips, I'd appreciate it.  Thanks.
