Ebony Black - 043 - Pottery Pigment Stain Colors Made in Germany Earthenware Stoneware Porcelain (40 g. (1,41 oz.))

I searched for "mason stains" for a lesson that I wanted to teach to my pottery class and these are most definitely not that. As the class progressed that students added more and more and more and nothing and the black LOOKED like it was changing a whole bunch BUT when I fired up the low fire (cone 05) sample tiles at 30% stain the clay was mostly white with BARELY a few flecks a look of grey to it (it burned away even at a lower temperature)I think that these may be concrete stains instead.
