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 this! I can't decide what color it is: it's black --or maybe it's very dark purple. It's got gray shadings --or maybe it's a very light brown. What keeps coming to mind is "Smoke."
And, clearly, it's not Field Mouse Brown! I think that I put a lot more cobalt carb than called for in the recipe... whatever it was I did, I hope that I can keep doing it.
Next step is to mix a 5000 gram batch and go for it!
