Does anyone have a reliable recipe of a Matt yellow (strong yellow)cone 6 glaze? I'm starting to make my own glazes and my attempts with a barium base turn out to be a beige glaze. Thank you in advance. Greetings from Brazil.

    Hi Billie, gerstley borate is 2% that will make it add up to 100%. You should use a white stoneware or porcelain. I mix my own but I also like the Laguna 550 Grolleg Porcelain. I fire to cone 6 but I prefer using cone 10 clay.

    You can also substitute zinc oxide for the barium carbonate, 15%. I think the pot in the photo used the zinc oxide.
