This time, it was successful to give an antique look to the leaf plates with glazes. I bisque-fired them to cone 5 (for durability), brushed Duncan Courtyard glazes on them, and glaze-fired them to cone 06. Yes, the bisque and glaze firing temperatures are purposely flipped. The particular glazes used here do not require thick coats. If you fire them higher than cone 06, the nice matte look will be destroyed. This alternative method seems to work.
