Deep Black with Bright-Blue Surface Effects
Polar Night BOTZ Earthenware Glaze develops a deep covering black with bright-blue effects and a glossy finish. The blue markings appear in scattered patches across the dark surface, giving simple bowls, faceted vessels and broad forms a strong contrast that lets the irregular glaze effect remain visible rather than disappearing into one uniform black.
Choose Polar Night when you want a black-dominant surface with visible blue variation rather than a plain, even black finish. It can also be used on coloured clay, so makers can explore how the deep black and blue effects sit over different clay colours while keeping the surface character of this glaze at the centre of the decoration.
