I am sorry to say, one of my favorite glazes has been discontinued by the manufacturer. I still have close to a gallon of "Pistachio" glaze in the studio, but from now on I cannot get any more. For obvious reasons, we are taking it off the website as a standard glaze option. If you want a small order in Pistachio, I can probably accommodate you. A big order, not so much. The good news is, we are replacing Pistachio with a lovely new "Gray" glaze, which I have big plans for!
It is pictured above on my new, 4"x4" Diagonal Tree of Life tile. And here it is on some 2"x2" Owl tiles (alongside some spirals in Celadon glaze):
