This is a test tile for a glaze I mixed last month as I was testing different colorants on a High Calcium Semimatte glaze from the Hesselberth & Roy book Mastering Cone 6 Glazes. The authors call this glaze "field mouse brown," but clearly it doesn't look brown at all and nothing like the example in the book. I was not going to go any further with this glaze, but something about it made me give it another try so I mixed a 1000 gram batch and here are the results. All I can say is Wow! I love…
