Glossy Turquoise Colour with a Developing Crackle Network
Turquoise Crackle BOTZ Earthenware Glaze creates a transparent to semi-transparent turquoise surface with a glossy crackle effect. Its network of fine lines adds visible structure while allowing the underlying surface to remain part of the finished appearance, with the attached examples showing both pale turquoise crackling and deeper blue-turquoise areas.
Choose this glaze when the crackle pattern itself is intended to become part of the decoration. Most cracks develop after cooling and can continue to strengthen for up to a week. On some clays, a slightly thicker coat on horizontal areas such as plate or bowl interiors can form darker turquoise scale crackles.
