"Night Sky" is actually a combination of glazes. To achieve this effect, I first brush the tile with a coat of black glaze. Then, with a damp sponge, I carefully wipe the black glaze off of the high points of the tile to allow the white clay to show through. Then I carefully cover the tile with a coat of clear glaze, being careful not to smear the black glaze. Because this process is more labor intensive than my normal method of glazing, there is an up-charge for tiles ordered in Night Sky glaze.
Below are some of the steps of the process of glazing tiles in "Night Sky."
