Test fired on Primo PW-20 to 1210 with a 10min soak (but not with the recommended Amaco firing schedule). Test tile brushed 2 and 3 coats and Test tile dipped both straight out of container. This turned out a dark brown colour, quite different to that pictured. Rating it is difficult given I didn't follow the Amaco firing schedule however some of their other glazes achieved the pictured results following my firing schedule so I need to play with it some more.
