I have used this glaze, I got a very bright dark red color with dark blue in textured areas. I applied two thick coats by dipping--it ran alot. Be careful not to get too hot or thick. I had to remove it from kiln shelves. I fired it to cone 6 using the firing schedule from Mastering cone 6 glazes. I will try again, but in a cooler spot of my kiln. I was a bit disappointed, I just haven't found that magical way of firing it yet.
