Blue Glazes
All of the following Blue glaze recipes and more can now be found on my new open-source ceramics recipes website, Glazy: https://glazy.org/search?base_type=460&type=750&cone=high
The following tests were fired in two Jingdezhen public kilns at approximately cone 12 and in my own kiln at cone 10. I just wanted to get a general idea of the blue glazes listed in High Fire Glazes.

Dark Water Blue
This recipe calls for 2% additional Iron Chromate, which I don’t have. I tried this glaze without the Iron Chromate, as well as substituting Iron Chromate for a combination of Red Iron Oxide and Chrome Oxide. I don’t know what this glaze is supposed to look like..
